10.22376/ijpbs.2019.10.1.p1-12 Volume 3 Issue 3 2012 (July - September) A sensitive and reliable quantitative high performance thin layer chromatographic method has been developed for the quantitation of camptothecin from the dry stem powder of lessThan i greaterThan Ervatamia heyneana lessThan /i greaterThan (Wall.) T. Cooke lessThan i greaterThan . lessThan /i greaterThan   lessThan i greaterThan Ervatamia heyneana lessThan /i greaterThan (Wall.) T. Cooke has anticancer activity [1]. Methanolic extract of the dry stem powder of lessThan i greaterThan Ervatamia heyneana lessThan /i greaterThan (Wall.) T. Cooke was used for carrying out TLC on silica gel 60 F lessThan sub greaterThan 254 lessThan /sub greaterThan plates. Detection and quantitation was performed by densitometric scan in fluorescence, by using mercury lamp at λ = 366 nm. Accuracy of the developed HPTLC method was checked by conducting the recovery study. The average percent content of camptothecin in stem powder of the used plant, as estimated by the proposed method, was found to be 0.041mg/g. The HPTLC method developed for the quantitative determination of camptothecin in lessThan i greaterThan Ervatamia heyneana (Wall.) T. Cooke lessThan /i greaterThan stem powder is rapid, simple and precise. Vidya Dighe, Gaurang Parekh, Dhanashri Mestry Camptothecin, Ervatamia heyneana (Wall.) T. Cooke, HPTLC, Apocynaceae 230-237
