Parkia biglobosa offers food, medicine and income to rural populations. A study, was undertaken in three agro-climatic zones in southern Mali, to characterise P. biglobosa populations. Plots of 0.25 ha each were established in fields and fallows and adult trees in the plots were monitored. Natural regeneration was monitored in five subplots of 12.5 m x 12.5 m = 156.25 m2 each within each plot and data were collected from 2019 to 2021. Natural regeneration of P. biglobosa was found to be very weak in all sites. The mean density of seedlings varied from 11 to 24 seedlings ha-1 with a decreasing trend from 2019 to 2021. In Zanzoni, where the weakest regeneration was observed, the density varied from 0 to 8 seedlings ha-1. The highest density of seedlings was observed in Somasso in 2019 (42 seedlings ha-1) and 2020 (30 seedlings ha-1). In 2021, the highest density was observed in Diou (25 seedlings ha-1). The weakness of natural regeneration is very alarming for this tree species facing several other threats (ageing and decreasing adult tree populations, sanitary constraints, several pressures, etc.). It is therefore very important and imperative to investigate ways for regenerating the species for its sustainability and for maintaining the parklands biodiversity. Artificial regeneration (planting), could be the one and ultimate way to ensure the sustainability of P. biglobosa.
biglobosa为农村人口提供食物、药品和收入。在马里南部的三个农业气候带进行了一项研究，以确定大叶蛙种群的特征。在田间和休耕地各建立0.25 ha的样地，监测样地内成树的生长情况。在每个地块内的五个12.5 m x 12.5 m = 156.25 m2的子地块中监测自然更新，并于2019年至2021年收集数据。各样地的自然再生能力都很弱。幼苗平均密度为11 ~ 24株ha-1, 2019 ~ 2021年呈下降趋势。在再生最弱的桑佐尼，密度为0 ~ 8株/ h。幼苗密度最高的年份是2019年(42株ha-1)和2020年(30株ha-1)。2021年，Diou的密度最高(25株ha-1)。自然再生的弱点是非常惊人的，这一树种面临着其他几个威胁(老化和减少的成年树种群，卫生限制，一些压力等)。因此，研究该物种的再生方法，以保持其可持续性和公园地的生物多样性是非常重要和迫切的。人工更新(种植)可能是保证白桦可持续性的唯一和最终途径。

Ethnoveterinary practices are still prevalent in rural livestock healthcare. This research contributes significantly to the understanding of biological resources employed in ethnoveterinary practices in the Haridwar district of Uttarakhand. This current study focuses on ethnoveterinary knowledge among ethnic populations in Haridwar and quantitatively documented the traditional knowledge about the usage of different medicinal herbs. The field survey was carried out at four sampling sites, i.e., Chilla range, Mohand range, Vindhyavasini hills, and Shyampur range. The ethnoveterinary information was documented and collected in the study areas through interviews, questionnaires, and group discussions with ethnic communities and traditional healers, primarily elderly shepherds and farmers. The collected data were quantitatively analysed utilizing the informant consensus factor (ICF), fidelity level (FL), and use value (UV). In this study, 102 medicinal plant species were identified in which herbs (58.8%) were the maximum used life forms. Leaves (27.1%) were found to be the most commonly used plant part. The oral mode of medication was used most often in the ethnoveterinary practices (79.4%) used. Quantitative analysis revealed that the most important species having high UV values for curing livestock was Zingiber officinale (L) (UV = 2.67). FL% values ranged between 27.8 to 100% and ICF values ranged from 0.97 to 0.99. This study reveals that a large variety of medicinal plant species are of great ethnoveterinary relevance and are used by informants in Haridwar to treat cattle ailments. Further phytochemical and pharmacological studies would be needed to determine the usefulness and safety of the identified plants, allowing communities to use them in a more cost-effective, and safe manner.

The present investigation aimed to study the genomic characterization and free radical scavenging potential of a traditional plant Volkameria inermis. A chloroplast genome rbcL was used in molecular characterization and it revealed the phylogeny and evolutionary affinities of V. inermis with the outgroups of the family through BLAST search based on Neighbor-Joining (NJ) analysis. The free radical scavenging potential of various extracts of V. inermis was observed at different concentrations (20, 40, 60, 80 and 100 μg/mL) in DPPH and ABTS in vitro models. Ascorbic acid (DPPH) and Trolox (ABTS) were used as standard. In DPPH assay, among the different extracts (hexane, chloroform, acetone, ethanol, methanol and water) tested, methanol showed maximum scavenging activity with the IC50 value of 28.33μg/mL followed by acetone with the IC50 value of 31.937μg/mL. The other extracts, ethanol and water extracts showed moderate activity with the IC 50 value of 82.558 μg/mL and 81.758μg/mL; chloroform and hexane showed very lower antioxidant activity and the IC50 values are 518.776μg/mL, 1066.16μg/mL accordingly. In ABTS assay, methanol was observed as a highly active extracts with the IC50 value of 70.196μg/mL followed by ethanol extract (103.078μg/mL). The results showed that the methanol extract exhibits strong antioxidant activity in DPPH and ABTS assays. The scavenging efficiency showed dose dependent increase in concentration absorption compared to Ascorbic acid and Trolox. Our findings provide the molecular identification and evidence for the potential of Volkameria inermis as a source of natural antioxidants.

Cancer is the most important health care problem worldwide. An estimated 10 million new cases worldwide are recorded annually, of which 46% are in developed countries. Breast cancer is one of the second most common malignant tumors in the world. All forms of cancer treatment, including surgical treatment, chemotherapy and/or radiotherapy are often poor and often toxic to the normal cell. Therefore, there is still an urgent need for new cancer treatment options. More research is now being done to determine which compounds occur naturally. The current study aims to extract Cardiospermum halicacabum L. for the prevention and treatment of cancer. A few methods may account for the perceived therapeutic effects, most importantly direct cytotoxicity. These herbal medicines when combined with regular antioxidant and anticancer drugs may be helpful in combining the antioxidant and anticancer effects and reducing the side effects associated with common drugs.

Suaeda maritima (L.) Dumort of the family Chenopodiaceae is an annual succulent mangrove herb. This annual salt marsh is quite regularly used by the local people for food and pharmaceutical. This species has been cursorily noted to have variation in some morphological characters. Earlier reports indicated the presence of triterpenoid e.g. alpha amyrin in some species of Suaeda. However, no report on the variation in the quantity of it in this species was presented. The present study has furnished an account of subtle variation in morphology of this herb growing on different sites in the area under study. It also shows a difference in the amount of alpha amyrin in the plant individuals of different places, revealed through the HPTLC study. Morphological variations have been noted mostly in respect of the characteristics of the stem and leaf of the species.

Ruta graveolens L. is an endemic plant of the Mediterranean region. It has been used for centuries as a medical preparation and has a variety of roles because of its varied chemical composition. In vitro culture is a useful tool for both multiplication and study of important secondary metabolites. The present study was aimed to develop an effective and reproducible protocol for callus induction and indirect plant regeneration of Ruta graveolens (L.) by using leaf explants and to analyze chemical components present in different extracts of Ruta graveolens. The leaf explants were cultured on MS medium augmented with different combinations and concentrations of auxins and cytokinins for callus induction, shoot multiplication and rooting. The optimum plant growth regulator concentration for callus induction, shoot multiplication and root formation was recorded in MSM+2,4-D(1.5mg/L)+NAA(1.5 mg/L), MSM+ BAP (1.5mg/L) +IBA (1.0 mg/L) and half strength MSM+IBA(0.50 mg/L) respectively. The rooted Plantlets were successfully acclimatized and established in earthen pots. The leaves, stem, roots and callus of Ruta graveolens were extracted by using Acetone and Ethyl acetate solvents followed by volatile compound analysis using GC-MS. The phytochemical assay showed that extracts of Ruta graveolens contain various phytoconstituents having potential bioactivity. The major compounds found were 1, 3-Dioxolane-4-propanol, 2, 2-Dimetheyl-, kokusaginine, Bergaptene, 2 Undecanone, 3-Hexene-2-one, Alpha, - 1- Arabinopyranose, 1, 2:3,4-bis-o, and 1- (1,3-Benzodioxol-5-ylmethyl)-3-Nitro-1 which might be primarily contributing in the biological activity of the plant. The results of this study will make a way for the production of herbal medicines for various ailments by using callus cultures of Ruta graveolens L.

The extant ethnomedicines of the Eastern Ghats of south India were inventoried. The ethnobotanical survey conducted during the months of June to August 2018 in the six different hills of Eastern Ghats divulged a total of 54 (76%) medicinal plants belonging to 34 families being currently used by the herbal practitioners. The comprehensive details on the vernacular name, binomial, family, and plant part(s) used, and type of drug preparation of the ethnomedicines used for the various disease(s) are tabulated. The plant family Fabaceae (with five ethnomedicines) followed by Euphorbiaceae and Solanaceae (four each) were the dominant contributor in the Eastern Ghats. Interestingly, the same families were found contributing in similar pattern (nine and four each) in the literature pertaining to the Eastern Ghats, indicating their heritage and significance. Further, the ethnobotanical survey revealed that the leaves (25%) and paste form (46%) are the predominant plant part and drug type used respectively in the hills. The analysis also revealed the prevalent use of single drug (70%) and their overall depletion (24%) underlining the urgency to conserve them.

Adaptogens are natural (herbs) or synthetic compounds (levamisole) used to maintain stability in human body. The plant based adaptogens were mainly used to enhance the physical endurance and metal health of patients. However, adaptogens are widely studied for their ability to protect and cope up the body against physical, chemical and biological stress and related diseases. Panax ginseng and Withania somnifera are natural adaptogens, used to attenuate stress & related disorders without increasing oxygen consumption. This review deals with a detailed description of adaptogenic potential of Panax ginseng and Withania somnifera in improving human health. It also focuses on the similarity and mechanism of action of Panax ginseng and Withania somnifera as adaptogens on human stress induced disorders.

Light Microscopy (LM) and Scanning Electron Microscopy (SEM) revealed the presence of chalk glands on both lower as well as upper surface of leaf and stem of both species. Chalk glands are abundant on lower surface and sparse on upper surface of leaf. Chalk glands are approximately hemispherical glands with oval or almost circular outline. It is composed of 8 cells arranged in two circles – central circle of 4 secretory cells and outer circle of 4 adjoining cells. Each secretory cell has depression which corresponds to pore. Each gland is surrounded by 4 subsidiary cells. No significant difference in the structure of chalk glands in both species was noticed. Chalk glands occupy three different positions with regard to epidermal cells –at the same level of the epidermis, slightly sunken in the epidermis and slightly raised above the epidermis. Common elements found in EDAX analysis of all chalk glands are carbon, oxygen, magnesium, sulphur, potassium and calcium. Differences in the presence of elements silicon, chlorine, aluminium, sodium, phosphorus were observed. The presence of significant amount of calcium in chalk glands and their dried deposits and absence of sodium and chlorine from dried deposits and even in some chalk glands appealed to use the term ‘Chalk gland’ instead of ‘Salt gland’ in Plumbago.
白杨属两种植物的茎和叶。P. zeylanica lin .andP.;蓝花林。对白垩腺体的结构和化学成分进行了研究。光镜和扫描电镜显示，两种植物的叶和茎的下表面和上表面都有白垩腺体。白垩腺体在叶的下表面丰富，在叶的上表面稀疏。白垩腺为近半球形腺体，轮廓为椭圆形或近圆形。它由8个细胞组成，排列成两个圆圈-中心圆圈由4个分泌细胞组成，外圆圈由4个相邻细胞组成。每个分泌细胞都有与毛孔相对应的凹陷。每个腺体被4个子细胞包围。两种白垩腺的结构无显著差异。白垩腺在表皮细胞中占据三个不同的位置——在表皮的同一水平上，在表皮中略微凹陷，在表皮之上略微凸起。在所有白垩腺体的EDAX分析中发现的常见元素是碳、氧、镁、硫、钾和钙。观察了硅、氯、铝、钠、磷等元素存在的差异。在白垩腺体及其干燥沉积物中存在大量钙，而在干燥沉积物中甚至在一些白垩腺体中缺乏钠和氯，因此在Plumbago中使用“白垩腺”而不是“盐腺”一词。

The primary result of our experiment revealed that the germination percentage of N. oleander mature seeds is only 30%. From this observation, the concept of protocol standardization for zygotic embryo culture of this plant was originated. Zygotic embryo culture was proved an efficient in vitro multiplication system of N. oleander. The maximum germination percentage (96%) of zygotic embryos was observed on ¼ MS medium with 15 gm/L sucrose, whereas the best growth medium was optimized as ½ B5 with same sucrose concentration. The second part of this study was aimed to find out the cardiac glycoside accumulation pattern in both in vitro and acclimatized plants. For this purpose, one-month-old in vitro plantlets and acclimatized plants were subjected to LC-MS analysis and 09 cardiac glycosides were detected and quantified in both the systems. Most of the cardiac glycosides including odoroside A (32.71 mg/gm DW), odoroside H (4.69 mg/gm DW) and oleandrin (0.52 mg/gm DW) were found to be accumulated at maximum level within in vitro plantlets. CG 840b (1.89 mg/gm DW) is the only cardiac glycoside, which was maximally accumulated in acclimatized plants. From this study, it can be concluded that, zygotic embryo culture is a better choice for in vitro multiplication of N. oleander when compared to matured seeds and in vitro grown plantlets of this species favor cardiac glycosides biosynthesis in comparison to acclimatized plants. Therefore, all future research on the enrichment of cardiac glycosides from this plant may be conducted on zygotic embryos derived in vitro grown plantlets or cultures.
