Isolation and Identification of Flavonoid "Quercetin" from Citrullus colocynthis (Linn.) Schrad
نویسندگان
چکیده
Citrullus colocynthis (Linn.) Schrad. is an important medicinal plant belonging to family Cucurbitaceae. Flavonoid "quercetin" was isolated from in vivo (leaf, stem, fruit and root) and in vitro callus of the species. The dried samples were separately soxhlet extracted in 80% methanol and then reextracted with petroleum ether, diethyl ether and ethyl acetate. The fraction was concentrated and subjected to TLC. The R f value of isolated quercetin and standard quercetin was calculated. The purified material was subjected to its IR spectra, HPLC and identified as "quercetin". This study is also of practical importance because quercetin is an important ingredient of Citrullus colocynthis.
