چکیده    The antiproliferative activity of hexane (f1),ethyl acetate (f2),butanol (f3) and water (f4) extracts of h. oblongifolium were tested in vitro for their anti- proliferative (anticancer) activity on the cell lines: ht-29 human colon adenocarcinoma,nci-h460 human non-small cell lung carcinoma,mcf-7 human breast cancer,ovcar-3 human ovarian adenocarcinoma and rxf-393 human renal cell carcinoma with etoposide as positive control. among the various extracts the f1 showed relatively potent anti-proliferative activity (10.55 ± 4.19 μg/ml) on ovcar-3 human ovarian adenocarcinoma cell growth almost equal to the activity of etoposide (9.42 ± 1.62 μg/ml). seven compounds were also isolated for the first time from this source. these phytochemicals were identified as 18?h-urs-20 (30)-en-3β-ol-28-oic acid (1),tetracosyl 3-(3,4-dihydroxyphenyl) acrylate (2),shikimic acid (3),1-octatriacontanol (4),hexacosyl tetracosanoate (5),β-sitosterol (6) and β-sitosterol3-o- β-d-glucopyranoside (7) on the basis of spectroscopic studies such as 1h nmr,13c nmr,2d nmr and mass spectroscopy as well as established with help of reported literature.
