Background and Objectives Blumea lacera (Burm.f.) DC. (Family—Asteraceae) is widely used for treating hemorrhoids by several ethnomedicinal practitioners and tribes in India. Thus, the main objective of the present investigation was to evaluate the potential of B. lacera leaf extract in the treatment of hemorrhoids using a croton oil-induced hemorrhoid rat model. Materials and Methods Ethanol extract of B. lacera (EBL) leaves was prepared using Soxhlet extraction, optimized using Box–Behnken design (BBD), and quantified using high-pressure liquid chromatography (HPLC). Furthermore, the vasoactive ions were estimated using ion-exchange chromatography. Hemorrhoids were induced in the recto-anal portion of experimental rats, followed by treatment with EBL (100, 200, and 400 mg/kg; par oral (p.o.)) and Pilex granules as a standard anti-hemorrhoid drug for 7 days. The anti-hemorrhoid potential was evaluated on the eighth day by assessing the severity of hemorrhoids, biochemical parameters, and histology of recto-anal tissue. Results Upon treatment with EBL and Pilex, there was a significant (p < 0.05) reduction in the inflammatory severity index, concentration of Evans blue dye, recto-anal coefficient (RAC), elevated cytokines level, and restoration of altered antioxidant status. Furthermore, the histopathological results revealed a marked reduction in the inflammatory zones along with minimally dilated blood vessels. Conclusion The present study confirmed the traditional claims of the plant B. lacera in the treatment of hemorrhoids, which may be attributed to its anti-inflammatory and antioxidant potential in EBL, where quercetin could be considered the main contributor.

Background Schisandrin A (SchA) has multiple pharmacological features, and inflammatory bowel disease (IBD) represents a common digestive system disease mainly characterized by inflammation. Objectives To assess the anti-inflammatory effects and the mechanism of SchA in mice with enteritis and in MODE-K cells representing in vivo and in vitro models of inflammation. Materials and Methods DSS-induced IBD mouse models and MODE-K cells (an in vitro model of the intestine) were used to assess the effects of SchA on IBD inflammation and to determine the related signaling pathways. Results Our data showed that SchA exerted anti-inflammatory effects by reducing the general clinical symptoms and the pathological damage to the colonic mucosa in mice with IBD and by promoting the migration of H2O2-induced MODE-K cells, inhibiting apoptotic death, and reducing the release of inflammatory factors. Moreover, SchA downregulated Wnt/β-catenin in both enteritis mice and H2O2-induced cells. Conclusion SchA inhibits inflammation in DSS-induced IBD mice and H2O2-induced MODE-K cells by repressing Wnt/β-catenin signaling.

Background Spirulina (Arthrospira platensis), a cyanobacterium, is being consumed worldwide owing to its high nutritional value and therapeutic potential. Objectives This study aims to determine the phytochemical content, antioxidant capacity, and antiglycation property of A. platensis PCC 7345 aqueous extract against glucose, fructose, and ribose-mediated glycation of hemoglobin. Materials and Methods The antioxidant property of the extract was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and a nitric oxide scavenging assay. Protein glycation and its subsequent prevention were interpreted by observing a reduction in browning, fructosamine, glycated hemoglobin (HbA1c) level, protein carbonyl content, advanced glycation end products (AGEs) formation, and protein aggregation using spectrophotometry and spectrofluorometry. The prevention of strand nicking/breaks in the pBR322 plasmid was analyzed using electrophoresis, and the change in integrated density was calculated using ImageJ software. Results The extract showed very good antioxidant potential, which is evident and could be estimated from the inhibition concentration (IC50) values that were 45.97, 31.09, and 52.29 µg/mL in the DPPH, ABTS, and nitric oxide scavenging assays, respectively. A. platensis aqueous extract was found to be the most effective in preventing glucose-mediated glycation and protein aggregation, wherein 100 µg/mL of the extract could effectively cause ~50% inhibition in the formation of early and AGEs and prevented the formation of protein aggregates. The highest antiglycating potential of the extract was observed in glucose-mediated glycation, followed by fructose and ribose. The formation of four fluorescent AGEs, such as argpyrimidine, vesper lysine A, pentosidine, and crossline, was reduced. The extract could prevent 97% of DNA nicking in pBR322. Conclusion The aqueous extract of A. platensis has a potent ability to prevent glycation and its secondary complications.

Background Kaempferia galanga, commonly known as aromatic ginger, is a potential herb with high medicinal value and is used to treat many diseases like diabetes and asthma. Cancer is a group of diseases characterized by abnormal cells that divide uncontrollably and spread throughout the body. Nowadays, medicinal plants are used for their essential oil activities, including anti-cancerous effects. Objectives The aim of this study is to establish a method for screening in vitro oil cytotoxic effects. Materials and Methods Murashige and Skoog (MS) medium with growth regulators like benzyladenine, kinetin, indole-3-acetic acid, adenine sulfate, and naphthalene acetic acid was used for plantlet production. The in vitro regenerated plants were studied for rhizome oil extraction using Clevenger’s apparatus and gas chromatography-mass spectrometry (GC-MS) analysis, followed by their cytotoxicity study against human cervical cancer cells (HeLa) and human breast cancer cells (MCF-7) by (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) tetrazolium reduction (MTT) assay. Results Upon analysis, it has been found that this medicinal plant contains ethyl-p-methoxycinnamate (EPMC) (56.41 ± 0.34%) as a vital compound in its rhizome oil. The validation of cytotoxicity in both cell lines was done by treatment with rhizome oil concentrations ranging from 6.25 to 100 µL, respectively. The IC 50 value was found to be 44.18 ± 0.65 µL/mL in HeLa and 72.94 ± 0.26 µL/mL in MCF-7 cells after 24 h of incubation. Conclusion The results of this study would be helpful for this important medicinal plant to be used by pharmaceuticals in the treatment of cancer.

Background Safflor yellow (SY) is a water-capacitive component of dried flowers, mainly from safflor in the safflower family, which contains a large amount of bruthin A, or Safflor yellow A (SYA) for short. Studies have reported the protective effects of SYA against oxidative stress injury in nerve cells. Materials and Methods In this study, H 2 O 2 -treated PC12 cells were used as experimental materials to explore how SYA plays a protective role against nerve cells after oxidative stress and to analyze the molecular mechanism of SYA. PC12 cells were treated with H 2 O 2 and SYA solution. Cell proliferation is then detected with Cell Counting Kit-8 (CCK-8). The detection method is 5-(and 6)-chloromethyl-2′,7′-dichloro-dihydrofluorescein diacetate (CM-H2DCF-DA) staining reactive oxygen species (ROS). Levels of apoptosis-related proteins, including Bcl2-associated X protein (Bax), B-cell lymphoma (Bcl-2), caspase-3, and cleaved caspase-3, and oxidative stress regulators, namely, nuclear factor erythroid-2-related actor 2 (Nrf2) and heme oxygenase 1 (HO-1), were detected by western blotting. Results The CCK-8 assay results showed that the survival rate of H 2 O 2 -induced PC12 cells was significantly increased after SYA treatment. Fluorescence microscopy (CM-H2DCF-DA staining) indicated that SYA decreased H 2 O 2 -induced apoptosis in PC12 cells by reducing intracellular ROS. Western blotting analysis showed that SYA upregulated the expression of Nrf2, HO-1, and Bcl-2 and downregulated the expression of Bax, caspase 3, and cleaved caspase-3 in H 2 O 2 -induced PC12 cells. Conclusion SYA does protect the nerve cells from oxidative stress damage. Its mechanism of action is mainly related to whether the Nrf2/HO-1 pathway is activated.

Background In Mexico, there is an ancestral custom about the knowledge of the medicinal use of plants. Bixa orellana L. is a plant species that represents one of the main crops used in traditional medicine in southeastern Mexico. Background studies on its biological properties have been conducted on accessions harvested in Conkal, Yucatan, Mexico. Objectives In this work, the idea was to perform a phytochemical analysis of methanolic extracts of B. orellana. Materials and Methods Phytochemical screening was performed on methanolic extracts of leaves and seeds from two accessions of B. orellana, as well as on their antioxidant and antiproliferative activities. Results The phytochemical screening of the methanolic extracts of the leaves revealed the presence of tannins, terpenes, and saponins. A higher total content of phenols and flavonoids in leaves was also found compared to seeds, which coincides with a higher antioxidant activity in leaves compared to seeds. Regarding antiproliferative activity, the seeds and leaves of accession 3 showed the best results. Conclusion Accession 3 has better bioactive properties and can be a candidate in the search for antiproliferative and antioxidant compounds; this is the first study that associates this plant with this activity and demonstrates the chemical differences that exist between the accessions of B. orellana.

Background Throughout the world, diabetic nephropathy has been treated by managing hyperglycemia and hypertension with antidiabetic and antihypertensive drugs, but the potency of reversing the diabetic nephropathy-induced complications is still questionable. Materials and Methods This study was focused on elucidating the nephroprotective effect of purpurin, a natural anthraquinone, against diabetic nephropathy induced in an in vivo model. Diabetic nephropathy was induced in rats by injecting streptozotocin (STZ) and then treating them with purpurin. The rats were analyzed for food intake, body weight gain, fasting blood glucose (FBG), glycated hemoglobin (HbA1c), serum insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) to analyze the anti-glycemic effect of purpurin on diabetic nephropathy-induced rats. The lipid profile, blood urea nitrogen (BUN), serum creatinine, and lactate dehydrogenase (LDH), and kidney injury molecule-1 (KIM-1) levels were assessed. Proinflammatory cytokines, such as tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and interleukin 6 (IL-6), were quantified to determine the anti-inflammatory effect of purpurin on diabetic nephropathy-induced rats. Finally, histopathological analysis of kidney tissue was performed. Results Purpurin effectively decreased the body weight, FBG, HbA1c, HOMA-IR values, and increased insulin levels. It significantly decreased lipid profiles while increasing high-density lipoprotein (HDL) in diabetic nephropathy-induced rats. It also decreased the BUN, creatinine, LDH, and KIM-1 levels. The reduction in proinflammatory cytokine levels was observed in the purpurin-treated diabetic nephropathy rats. Finally, the histopathological analysis confirms the nephroprotective effect of purpurin. Conclusion Taken together, our results conclude that purpurin possesses therapeutic potency to ameliorate diabetic-induced nephropathy, and it can be a promising drug for diabetic nephropathy in the future.

Background Scutellaria baicalensis is an important medicinal plant used in China. Several compounds have been extracted from S. baicalensis using modern techniques. Baicalin, an active ingredient of S. baicalensis, is widely used clinically. However, its clinical use is limited owing to poor oral bioavailability and intestinal absorption. Objectives To evaluate the anti-tumor effect of baicalin magnesium salt (BA-MG, a novel magnesium salt form of baicalin with superior water solubility) on the human hepatocellular carcinoma cell line, HepG2. Materials and Methods Seven groups were established, including three dosages of BA-MG (200, 250, and 300 µg/mL), baicalin, dimethyl sulfoxide (DMSO) (negative control), magnesium sulfate (negative control), and control groups. Cell proliferation was determined using the cell counting kit-8 (CCK-8) assay. Cell cycle and apoptosis were detected by flow cytometry. Cell migration was determined using a cell scratch assay. Protein expression was determined using western blotting. Results In vitro, BA-MG inhibited proliferation, reduced cell cloning and migration abilities, induced cell cycle arrest, and promoted apoptosis of HepG2 cells (all p < 0.05). The effects of baicalin and BA-MG on proliferation and migration, cell cycle, and apoptosis may be attributed to decreasing the expression of Bcl-2, ROCK-1, proliferating cell nuclear antigen (PCNA), and cyclin E, as well as increasing the expression of Bax and caspase-9. The efficacy of BA-MG is superior to that of baicalin at the same dose. Conclusion BA-MG showed superior effects on inhibiting cell proliferation and inducing apoptosis in liver cancer cells.

Background Leaves, flowers and young shoots of yellow Camellia species are often used as a substitute for green tea in Vietnam. Yellow Camellia species contain high levels of polyphenol compounds, and have shown activities such as antioxidant, anticancer, and cytotoxic. Objectives We qualitatively screened phytochemicals, quantified total polyphenols of 70% ethanol (EtOH) extracts of leaves, young shoots, and flowers of Camellia vuquangensis and Camellia hatinhensis in Ha Tinh Province, Vietnam. Furthermore, these extracts have been evaluated for lipid peroxidation inhibitory activities at the in vivo level in the BALB/c mouse model, and in vitro cytotoxic activities. Materials and Methods Chemical methods and thin-layer chromatographic (TLC) analysis were used for the qualitative screening of phytochemicals. High-performance liquid chromatography (HPLC) was used to determine total polyphenols. Cell survival was determined through optical density (OD) measured when the protein composition of the cells was stained with sulforhodamine B (SRB). Inhibition of lipid peroxidation was evaluated by determining the content of malondialdehyde (MDA), which is a product of membrane lipid peroxidation. Results The total polyphenol contents of all parts of the two species were comparable to that of green tea with values between 319.3 and 342.6 mg gallic acid equivalents (GAE/g) dry weight. Extracts of leaves, flowers of C. vuquangensis and C. hatinhensis showed strong lipid peroxidation inhibitory activities (IC50: 7.92–17.45 µg/mL) and moderate cytotoxic activities against cell lines HepG2, A549, MCF7, SK-Mel-2, HT-29, and AGS (IC50: 34.73–80.58 µg/mL). Conclusion These two tea species may be considered as herbal teas with various health benefits.

Background: Plants belonging to the genus Viola and family Violaceae are well known in Ayurvedic and Unani medicine for their pharmaceutical importance. Viola, commonly known as Banafsha, has been traditionally used as an anti-malarial. The goal of this study was to determine the anti-Plasmodial activity of the cyclotide-rich crude methanol/water extract of leaves from Viola canescens Wall and to analyze its constituents by mass spectrometry (MS). Materials and Methods: Liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) involving quadrupole time-of-flight (Q-ToF) and matrix-assisted laser desorption/ionization (MALDI)-time-of-flight-mass spectrometry (ToF-MS) were applied to investigate the cyclotides rich in methanol/water extract. The intact molecular masses were observed in the range of 2,800–3,400 Daltons, suggesting the presence of peptides. Since various head-to-tail cyclized and intramolecularly disulfide-bonded peptides known as cyclotides have been identified in the Violaceae family, we wanted to verify whether cyclotides are present in our extract. So, the intact masses inferred from the observed spectra were interrogated with Cybase (www.cybase.org.au), which is a database on plant cyclotides. Results: We observed promising anti-Plasmodial activity (IC50 44 µg/ml) in the cyclotide-rich methanol/water extract prepared from the leaves of the Himalayan V. canescens Wall. The output obtained from Cybase confirmed the presence of about 20 different cyclotides in our extracts. However, no sequence information could be obtained from Cybase for 14 intact molecular masses, which were inferred from the observed LC-ESI-MS data. Hence, these could correspond to novel peptide/cyclotide sequences, which might be characteristic of Himalayan V. canescens. Conclusion: This is the first report on the anti-Plasmodial activity of the cyclotide-enriched methanol/water crude extract of the leaves of V. canescens.
