摘要: Previous report showed the high potent antiproliferative effect of methanolic part extracted from aerial parts Pouzolzia indica on NB4 and HT93A acute leukemic cell lines with IC50 values 28.5 49.8 μg/mL, respectively. The bioassay-guided fractionation gave 5 fractions, that is, FFI–FFV. FFII, FFIII, FFIV inhibited above 15.1 (FFII), 14.4 (FFIII), 32.1 (FFIV), 31.0 9.7 10.5 (FFIV) μg/mL, compounds in these fractions were isolated using chromatographic technique. FFII contained friedelin 1, 28-hydroxy-3-friedelanone 2, 7-methoxy-coumarin 3. FFIII 6, 7-dimethoxy-coumarin 4, scopoletin 5, methyl caffeate 6. sitosteryl glucoside 7 a supposed glycosphingolipid 8. chemical structures elucidated by spectroscopic methods.
