Identification and isolation of antimicrobial compounds from the flower extract of Hibiscus rosa-sinensis L: In silico and in vitro approaches.

The modern people are preparing the natural medicines from the plants and their parts for curing various diseases. The present study was chosen Hibiscus rosa-sinensis flowers to analyze its antimicrobial capabilities against venereal diseases causing pathogens. In this study, the antimicrobial activity performed in different solvents prepared flower extracts using agar well diffusion method. Among the extracts, the methanolic flower extract of Hibiscus rosa-sinensis shows better results than other solvents extracts. The extract analysed by GC-MS which was exposes seven bioactive molecules. These bioactive molecules were docked with N. gonorrhoea protein. Finally, benzene dicarboxylic acid had best glide docking XP scores -7.955 with better binding energy values (-38.692 kcal/mol) than other ligand molecules. Hence, this molecule was isolated from the flowers of H. rosa-sinensis. After that, the different concentrations of 1,2 benzene dicarboxylic acid were tested on human diseases causing microbial strains. There, all the levels were showed good anti-gonorrhoeal activity against N. gonorrhoeae. Hence this study suggested that 1,2 benzene dicarboxylic acid could be used as a better drug candidate for venereal diseases.

Traditional plants used for the treatment of gynaecological disorders in Vedaranyam taluk, South India - An ethnomedicinal survey.

Gynaecological disorder is one of the most severe conditions under reproductive health. So we investigate and collect information from traditional practitioners on the use of medicinal plants for treatment of Gynaecological disorder in Vedaranyam taluk, Nagappattinam district of South India. The field study was carried out for a period of January 2014-January 2015 in Vedaranyam taluk, Nagappattinam district of South India. This is the first traditional medicine study in which statistical calculations about plants are done by RFC, CI, UV and ICF in the study area. The ethnomedicinal information was collected through interviews, informal meetings, open and group discussions and overt observations with semi-structured questionnaires among traditional practitioners. A total of 66 species of plants distributed in 62 genera belonging to 44 families were identified as commonly used ethno medicinal plants by traditional practitioners in Vedaranyam taluk for the treatment of 36 ailments based on the reproductive systems treated. Leaves were the most frequently used plant parts and most of the medicines were prepared in the form of paste and administrated orally. We know the most important species according to their use value such as Moringa oleifera, Smailax zeylanica and Achyranthes aspera were recorded. The present study, we have highlighted some claims which are high use in the study area. Further pharmacological studies of these plants may provide some important drugs for the treatment of common gynaecological disorders.

Quantitative ethnomedicinal study of plants used in the Nelliyampathy hills of Kerala, India.

ETHNOPHARMACOLOGICAL RELEVANCE: Inspite of tremendous advances made in allopathic medical practices, medicinal plants have played an important role throughout the world in treating and preventing a variety of diseases and hence there is urgency in recording such data. This is the first ethnobotanical study in which statistical calculations about plants are done by the Pearson correlation coefficient (PCC) method. The present study was aimed to identify plants collected for medicinal purposes by the traditional healers of Nelliyampathy hills, located in Palakkad district of Kerala, India and to document the traditional names, preparation and uses of these plants. METHODS: The field study was carried out over a period of 2 years (2011-2013) using semi-structured interviews with 66 informants (most of the informants belonged to an age between 50 and 70 years) in six remote locations in the hills. Ethnomedicinal data was analyzed using frequency citation (FC), relative frequency of citation (RFC) and use value (UV) along with a Pearson correlation coefficient (PCC). Demographic characteristics of participants, ethnobotanical inventory of plants and data on medicinal application and administration were recorded. RESULTS: A total of 85 medicinal plants belonging to 49 families were reported to be used against 19 different ailments in the hills. The maximum reported medicinal plant families were Cucurbitaceae with 6 species followed by Acanthaceae, Malvaceae and Fabaceae (each 5 species), Asteraceae, Lamiaceae, Moraceae and Myrtaceae (each 3 species), the most dominant life form of the species includes herbs (42) followed by tree (20), climber (15) and shrub (8), the most frequent used part was leaves (40%) followed by root (14%), seed and flowers (each12%), fruit (9%), bark (7%), stem (2%), latex (2%), rhizome and whole plant (each 1%), the most common preparation and administration methods were paste (32%), powder (22%), decoction and juice (each 20%) and raw (4%), infusion and inhalation (each1% ). The Pearson correlation coefficient between RFC and UV was 0.638 showing highly positive significant association. CONCLUSIONS: In this study, we have documented considerable indigenous knowledge about the native medicinal plants in Nelliyampathy hills for treating common ailments. The plants such as further investigated phytochemically and pharmacologically which leads to natural drug discovery development may be based on the present study. The study has various socioeconomic dimensions which are associated with the local communities.
