Three compounds have been isolated from the dichloromethane soluble fraction of the fruiting body of Ganoderma lucidum (Fr.) Karst. On basis of spectral analyses (UV, IR, MS, 1HNMR, 13CNMR and 2D-NMR), they were identified as 3, 7-dioxo-lanosta-8, 24(E)-dien-26-oic acid (I), 7 beta-15
Four major triterpenoids (ganoderic acids C(2), B, K and H) in rat plasma after oral administration of G. lucidum extract were analyzed quantitatively by high-performance liquid chromatography (HPLC). Plasma samples taken from rats were acidified with hydrochloric acid and extracted with
A sensitive and simple high-performance liquid chromatography (HPLC) method was applied for the quantitative determination of four major triterpenoids (ganoderic acids C(2), B, K and H) in rat urine after oral administration of total triterpenoids from Ganoderma lucidum. The urine sample was
