Abstract:
Objective To investigate the chemical constituents from Pholidota rupestris. Methods The chemical constituents from the EtOAc soluble fraction of P. rupestris were studied and 13 compounds were isolated by the method of silica gel column chromatography. The structures of these compounds were elucidated by spectral analyses and chemical properties. Results Thirteen compounds were isolated and identified as confusarin (1), ochrone A (2), coelonin (3), lusianthridin (4), batatanin III (5), gigantol (6), thunalbene (7), cyclopholidone (8), cyclopholidonol (9), syringaresinol (10), β-sitosterol (11), stigamast-5-ene-3β,7α-diol (12), and 5α,8α-epidioxy-(22E,24R)-ergosta-6,22-dien-3β-ol (13). Conclusion All compounds are isolated from this plant for the first time. Compounds 1, 2, and 12 have not been recorded in the genus Pholidota.
