抄録
Poria cocos (Fuling), a popular Chinese medicinal (CM) herb of fungal origin, has been included in many combinations with other CM herbs for its traditionally claimed activities of inducing diuresis, excreting dampness, invigorating the spleen and tranquilizing the mind and its modern pharmacological use of modulating the immune system of the body. Dehydrotumulosic acid, one of the effective constituents of Fuling, was isolated from the chloroform-soluble material of ethanol extract of the fungus. After further purification by a high-performance liquid chromatographic method on a C18 column, the purified constituent was identified using modern analytical techniques, such as UV, 13C-NMR and EI-MS. A reversed-phase high-performance liquid chromatographic method has been developed for the determination of dehydrotumulosic acid in Poria cocos. The determination can be accomplished in less than 50 min using methanol-acetonitrile-2% glacial acetic acid as the mobile phase at a flow rate of 1.0 mL/min, with a UV detector setting at 242 nm and testosterone propionate used as an internal standard. This assay for dehydrotumulosic acid is simple, rapid and with good reproducibility.
