Chemical constituents and bioactivity of Kalimeris indica
Objective To study the chemical constituents from Kalimeris indica.Methods Chemical constituents were isolated by column chromatography and semi-prepared HPLC,and the structures were elucidated by spectral data and physical-chemical properties.Results Fifthteen compounds were isolated and respectively identified as friedelin (1),epifriedelanol (2),stimasterol (3),β-sitosterol (4),u-spinasterol (5),erythodiol (6),octadecanoic acid (7),fraxinellone (8),[β-daucosterol (9),hexacosanol (10),ergoaterol (11),sphondin (12),dibntyl phthalate (13),oleanic acid (14),and dammerdienly acetate (15).Conclusion Compounds 5,8-13 are isolated from K.indica for the frist time.Compounds 1,3,5,8,and 12 have inhibitory effects on Cytospora sp.and Rhizoctonia solani.
