Pharmacognosy Research 2017 9(5):27-33 Objective: The objective of this study is to evaluate a meticulous pharmacognostic cram is to supplement constructive information with regard to its identification, characterization, and standardization of endemic and endangered medicinal climber Cayratia pedata var. glabra and also screening the antibacterial activity of this climber. Materials and Methods: The morphological characters of study plant, microscopic examination of leaf powder, anatomy of young stem, physicochemical analysis of plant powder, extractive values, phytochemical analysis, powder with different chemical reagents, fluorescence analysis of plant powder, and other World Health Organization (WHO) recommended for standardization were analyzed. The antibacterial activity of this study plant is also analyzed. Results: C. pedata var . glabra belongs to the family Vitaceae, commonly known as “Kattuppirandai” is one such endemic and endangered species in Thaisholai, Nilgiris South Division, Western Ghats. With the patronage of veteran ethnic group traditional knowledge of this region, the species C. pedata var . glabra was selected for the pharmacognostical examination and antibacterial screening. There were no pharmacognostical reports of this plant, specifically to determine the anatomical and other physicochemical standards required for its quality control. The current study deals with pharmacognostical parameters for the aerial parts of study plant, which mainly consists of macromorphological and microanatomical characters, physicochemical constants (ash values and extractive values), fluorescence analysis, and phytochemical screening, one of the WHO accepted parameter for the identification of medicinal plants. The pharmacognostical exploration was undertaken for this species with the purpose of sketch the pharmacopeial standards. The antibacterial activity of this plant confirms the therapeutic power. Conclusion: The information obtained from pharmacognostical studies will be of used for supplementary pharmacological and therapeutical evaluation of the species and will assist in standardization for quality, purity, and authentication with the help, of which adulteration and substitution can be prevented. The antibacterial activity of this plant confirm the traditional knowledge of local healers on the wound healing property of this species and also suggest this plant species can be used as a promising source for the development of new pharmaceuticals that address the therapeutic needs to cure infectious diseases.
