摘要

A new isoflavone (1), along with daidzein (2), and genistin (3) were isolated from the Jacaranda obtusifolia twig extract. Their structures were elucidated by NMR and MS spectroscopy. Compound 1 possessed significant anticancer activity against KB and NCI-H187 cell lines with the IC_(50) values of 2.52 and 7.47 mug ml/1, compound 2 and 3 exhibited anticancer activity against KB and NC1-H187 cell lines with the 1C_(50) values of 5.73, 8.14, 2.83 and 27.30 ug mK~(-1), respectively. Compound 2 also showed anticancer activity against MCF-7 cell line with an IC_(50) value of 28.17 ug mL~(-1)'. The isolates showed non-
