Abstract
Stemonal and 6-deoxyclitoriacetal, rotenoid compounds were isolated from the dried roots of Stemona collinsae Craib. Stemonal was recrystallized with methanol. Crystal structure of stemonal displayed only the planar structures while that of 6-deoxyclitoriacetal showed both the planar and bent shape structures. Stemonal and 6-deoxyclitoriacetal were tested their cytotoxic activities against three cancer cell lines and found that only 6-deoxyclitoriacetal has been showed the cytotoxicity.
