Andrographis lineata Nees is an erect herb and has been used as a traditional medicine against many diseases. The present study was to investigate the phytochemical analysis and antibacterial activity of A. lineata plant extracts. The methanolic extracts of A. lineata showed a variety of phytochemicals such as alkaloids, flavonoids, phenols, tannins, terpenoids etc. The quantitative estimation of major phytochemical constituents revealed maximum amount of phenolic content in the roots and alkaloids in both the stem and leaf. Correspondingly, the highest amount of tannins and terpenoids were recorded in the leaf and flavonoids in the root samples. Furthermore, the plant extracts of A. lineata showed antibacterial activity against both Gram-positive and Gram-negative bacterial strains. Comparatively, stem extract was effective against Streptococcus mutans (18.19±0.04 mm), leaf extract against Enterobacter faecalis (24.13±0.14 mm) and root extract against Bacillus subtilis (24.09±0.14 mm) at 30 μg/μL concentration. However, the leaf extract was more effective against Escherichia coli (25.13±0.16 mm), Pseudomonas aeruginosa (20.20±0.13 mm) and Klebsiella pneumoniae (18.18±0.17 mm) at 30 μg/μL concentration. The studies infer that the phytochemical constituents of A. lineata have antibacterial properties and these herbs may be considered as the medicinal plant for treating bacterial diseases.

Candidiasis, especially by Candida albicans is the most prevalent disease over the years. To control the infection, several synthetic drugs and their formulations have been applied. Although antifungals are quite effective in treating candidiasis, long term use has been reported to have side effects. Nevertheless, it has other drawbacks such as efficiency as well as cost, recurrence of the infection, emergences of resistant strains etc. Thus, plant based natural compounds are being investigated for their antifungal activity. In the present study, five different plant extracts assessed exhibited retardation of growth and protease production (molar concentration) in C. albicans. The mycelia form of the organism showed growth resistance to tested plant extracts than the yeast extract form which conferred the higher pathogenicity of the mycelia form. The minimum inhibitory concentration (MIC) of each plant extract was experimentally evidenced with the oil obtained from the seeds of Pongamia glabrata showed the MIC values at the lowest concentration (20-30 μL/mL), followed by seed oil of Azadirachta indica and Ricinus communis. The order of candidostatic efficacy of the various oils was observed to be: Pongamia > Azadirachta > Ricinus > Eucalyptus > Curcuma. These findings have paved the way for further investigation of plant based antifungal agents and their clinical appropriateness for the treatment of Candidiasis.

Higher plants have long been used as traditional medicines to treat human ailments. Approximately 80% of people worldwide utilize plants as safe sources of medicines to heal human diseases via a totally new medicinal system. Holigarna ferruginea is an indigenous medicinal tree plant in the Anacardiaceae family. The plant has a wide range of physiologically active chemicals. GC-MS was used to screen phytochemical substances, while FTIR was used to identify functional groups. GC-MS study revealed 10 major bioactive phytochemical substances that belong to functional groups such as secondary amines, alcohols, ethers, esters, carboxylic acids, and anhydrides. These diverse active phytochemicals have been discovered to have a wide range of actions that may aid in the prevention of illnesses. Higher quantities of phytochemical substances were found in ethyl acetate extracts of leaves. As a result, the extract possesses anticancer and antioxidant activities against Humans Breast cell lines (MCF-7). The viability was reduced when the concentrations of the ethyl acetate extract of H. ferruginea leaves were increased and it may help in the discovery of an ideal therapeutic agent in novel drugs as well as nutritional supplements.

Ethno-veterinary medicinal plants are important as they are used extensively in many rural areas of the world where people heavily rely on traditional herbal treatments to treat their domestic animals. Indigenous herbal remedies utilized for centuries to keep animals healthy and verbally passed down through the generations. Charkhi Dadri is a district of Haryana situated in the Trans-Gangetic Plains area of India. A total of 45 distinct medicinal plants were studied from 31 families to explore their ethno-veterinary uses of which herbs comprised the majority of the plants followed by trees, shrubs, and climbers. The seeds, leaves and whole plants are the most popular plant parts used. The people can use the documentation of this native knowledge to promote the adoption of traditional methods for treating livestock problems since time immemorial. The findings of this study demonstrate the viability of traditional medicine, which primarily relies on the usage of medicinal herbs to provide for the healthcare needs of cattle in the Charkhi Dadri District of Haryana. The information gathered from the region’s livestock farmers may also utilize to manage the nation’s system for caring for livestock and enhance the quality of life in humans.

Plants are a vital and life-sustaining natural resource as they provide many ecosystem services and supply food, fibre, fuel, medicine, etc. They are distributed heterogeneously in different ecosystems. With the increasing urbanization in all parts of the world, the vegetation overlapped with urban localities like parks, gardens, roadsides, wasteland and other human habitations. Among this vegetation, many of them are used in ethnomedicine or in ayurvedic medicine by people for a long period of time. These valuable plant resources are now under threat due to various anthropogenic activities in the urban landscape. Bhuj is a small historic city in the arid zone of India with a rich diversity of medicinal plants. With the increasing human population and associated developmental activities within the city, many of these plants are under threat of extinction. Therefore, an attempt was made to document these medicinal plants distributed in different parts of the city and their uses for ethnomedicinal purposes. The plants were intensively surveyed and documented using a questionnaire survey, discussion and cross-checked with available literature. A total of 123 species of ethnomedicinal plants were documented and analysed for their uses in curing different health problems and conservation purposes in the urban landscape.

A new species of Selaginella i.e., Selaginella likabalika is described in the present study. The species was collected from Likabali, under the Lower Siang district and Karsingsa, under the Papumpare district of Arunachal Pradesh. The new species can be easily confused to be mosses due to their similar appearance and habitat resemblance. The species is minute, prostrate and generally covers the ground like a carpet. The morphology of the new species is close to Selaginella armata, S. apoda, S. confusa and S. flacca but can be differentiated by leaf features.

The analysis of pollen grains found in honey, known as melissopalynology, reveals pertinent details about the pollen and nectar sources in a location where bees produce honey, allowing researchers to identify the honey’s geographical and botanical origins. To determine the significant source plants in the area, the present analysis is conducted on five samples of winter honey that were collected from Prayagraj’s urban localities (Dahi, Baksi, Sirsa, Soraon, and Phoolpur). The methodology recommended by the International Commission of Bee Botany (ICBB) was followed in this study. Analysis of 5 honey samples recorded a diversity of 31 pollen types and one fungal spore type. The majority of pollen grains recovered from honey samples belong to entomophilous taxa (66%), 25% of the pollen is from anemophilous taxa, and 9% from amphiphilous taxa. Four honey samples (S1, S2, S3, and S5) were found to be unifloral while the remaining samples (S4) were multi-floral. The field mustard i.e. Brassica campestris L. was the predominant pollen type. The secondary frequency class contained three different pollen types, while the minor and significant minor frequency classes contained 14 and 30, respectively. With respect to the frequency of occurrence of pollen types in honey samples, field mustard was found to be a very common pollen type as they were recovered from more than 50% of the collected honey samples. The various type of pollen and spores were also observed in collected honey samples.

Zilla spinosa L. is a medicinal plant widely used in traditional Algerian phytotherapy against urinary lithiasis. The present study aims to evaluate the antioxidant and anti-inflammatory effects of different extracts from the aerial part of this plant. The antioxidant activity of the extracts was examined by two different methods, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and cupric reducing antioxidant capacity (CUPRAC). The anti-inflammatory activity of Z. spinosa was determined by the protein denaturation method. The qualitative phytochemical screening shows the presence of the majority of secondary metabolites in the aerial parts except anthraquinones and steroids, on the other hand, the root is characterized by the absence of several metabolites except tannins and coumarins.The ethyl acetate fraction displayed the highest antioxidant capacity (IC50 value: 10.47±0.18 μg/mL in DPPH assay, and A0.50 value: 40.89 ± 0.86 μg/mL in CUPRAC). The percentage of inhibition of BSA denaturation (0.2%) is proportional to the concentration of the different plant extracts, where the highest percentage was recorded in the concentrations of ethyl acetate 500; 250 μg/mL compared to Diclofenac (75 mg/3 mL), in contrast to the aqueous extract which gave non-significant results compared to the standards (p≥5℅). In comparison to the standards used in this study, the ethyl acetate extract demonstrated better DPPH inhibitory activity, while all organic extracts demonstrated lower CUPRAC inhibitory activity but higher anti-inflammatory activity.

The antioxidant activity of the extracts was examined by two different methods, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and cupric reducing antioxidant capacity (CUPRAC). The anti-inflammatory activity of Z. spinosa was determined by the protein denaturation method. The qualitative phytochemical screening shows the presence of the majority of secondary metabolites in the aerial parts except anthraquinones and steroids, on the other hand, the root is characterized by the absence of several metabolites except tannins and coumarins.The ethyl acetate fraction displayed the highest antioxidant capacity (IC50 value: 10.47±0.18 μg/mL in DPPH assay, and A0.50 value: 40.89 ± 0.86 μg/mL in CUPRAC). The percentage of inhibition of BSA denaturation (0.2%) is proportional to the concentration of the different plant extracts, where the highest percentage was recorded in the concentrations of ethyl acetate 500; 250 μg/mL compared to Diclofenac (75 mg/3 mL), in contrast to the aqueous extract which gave non-significant results compared to the standards (p≥5℅). In comparison to the standards used in this study, the ethyl acetate extract demonstrated better DPPH inhibitory activity, while all organic extracts demonstrated lower CUPRAC inhibitory activity but higher anti-inflammatory activity.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73666721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
