ABSTRACT
We find many references in Ayurveda regarding Durva in management of epistaxis, hematuria, scabies, fever, burning sensation, chronic diarrhea, dysentery, anasarca, dropsy catarrhal opthalmia, dysuria, bleeding piles, eye infection, epilepsy, hysteria, insanity[1] bleeding, wound healing and other purposes. It is used as ingredient of several important preparations like, Durvadi tailam, Durvadi ghrutam, manaasmitravatakam. Standardization of herbs is essential to assess the quality of drugs. This study reports on physicochemical standardization of durva. Durva churna was prepared by proper drying. Its methanol extract, ethanol extract, chloroform extract prepared by soxhlet technique and water extract prepared by cold maceration technique. It standardized on the basis of organoleptic characters, physical characteristics, Physico-chemical, properties and thin layer chromatography (TLC) methods. Foreign matter nil, Total Ash 8.287% w/w, Acid insoluble Ash 4.466% w/w, Water Soluble extract 15.596% w/w, Alcohol Soluble Extractive 11.04% w/w, Methanol Soluble Extractive 12.828% w/w, chloroform Soluble Extractive 3.740% w/w. Thin Layer chromatographic analysis (TLC) showed 3 and 6 picks at 254nm and 366nm respectively. This study was aimed at analytical parameters of Cynodon dactylon. These parameters help in standardizing the durva and give us an idea of photochemistry of durva according to extracts.
