ABSTRACT
OBJECTIVE: To study the chemical constituents of Ramaria flava. METHODS: Several chromatographic methods were used to isolate the chemical constituents from this mushroom. Their structures were elucidated on the basis of spectral data. RESULTS: Eleven compounds were identified as: adenine (I), 5α, 8α-epidioxyergosta-6, 22-diene-3β-ol (II), 5α, 8α-epidioxyergos-ta-6, 9(11), 22-triene-3β-ol (III), Phenylacetic acid (IV), Bis (2-ethylhexyl) phthalate (V), 5α, 8α-epidioxyergosta-6, 9 (11)-diene-3β-ol (VI), stigmasterol (VII), D-allitol (VIE), α-D-(+) Glucose (IX), 3-O-β-Z)-Glucopyranosyl-22E, 24R-5α, 8α-epidioxy-ergosta-6, 22-diene (X), and 3-O-β-D-Glucopyranosyl-22E, 24R-5α, 8α-epidioxyergosta-6, 9, 22-triene(XI). CONCLUSION: All the 11 compounds were isolated from Ramaria flava for the first time. Copyright 2012 by the Chinese Pharmaceutical Association.
ABSTRACT
The chemical constituents of the gorgonian Isis minorbrachlasta have been studied for the first time. Th?marine specimen was collected off the Nansha Islands in the South China Sea . On the basis of spectral correlation (1H NMR,13C NMR,IR)four known compounds:gorgosterol,22 - epi-hippuristanol, ceramide and batyl alcohol, were indentified.
