Abstract:
The triterpenoids of Dichrocephala benthamii were investigated by means of silica gel, Sephadex LH-20 and semi-preparative HPLC. Nine triterpenoids were isolated from D. benthamii. By analysis of the EI-MS, NMR spectra and comparison to the data reported in literatures, the structures of these compounds were determined as β-amyrin formiate (1), β-amyrin acetate (2), β-amyrenol (3), β-amyrone (4), 3β-hydroxy-olean-11, 13 (18)-diene (5) , Δ12-oleanene (6) , friedelin (7), dammaradienyl acetate (8), epi-friedeband (9), respectively. Compounds 1-8 were isolated for the first time form this genus, compound 9 was isolated for the first time from this plant, whereas β-amyrin formiate (1) was a new natural product.
