Applications

Dehydrotumulosic acid, one of the effective constituents of Poria cocos, was isolated from the chloroform-soluble material of ethanol extract of the fungus. Poria cocos, a popular Chinese medicinal 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[1].

Abstract

A high-performance liquid chromatographic method for the determination of dehydrotumulosic acid in plasma of rats having been administrated orally with the traditional Chinese medicinal preparation Ling-Gui-Zhu-Gan decoction was developed. Plasma samples taken from rats were acidified with hydrochloric acid and extracted with ethyl acetate. Separation of the main effective constituent dehydrotumulosic acid was accomplished on a C(18) stationary phase and a mobile phase of methanol-acetonitrile-2% glacial acetic acid (13:12:10, v/v), with a UV detector setting at 242 nm. After validation, the method was used for preliminary investigation of the pharmacokinetic profiles of dehydrotumulosic acid administrated in Ling-Gui-Zhu-Gan decoction.

Abstract

Pachymic and dehydrotumulosic acids were studied in different models of acute and chronic inflammation. They proved to be active in most of the methods applied. None of them were active against arachidonic acid-induced ear edema. Dehydrotumulosic acid significantly diminished the mouse ear edema induced by ethyl phenylpropiolate, while pachymic acid was ineffective. When the putative corticoid-like mechanism of both compounds was explored, pachymic acid activity was partially abolished by the glucocorticoid receptor antagonist progesterone, but dehydrotumulosic acid activity was not affected. In vivo experiments demonstrated the inhibition by both principles of the phospholipase A2 (PLA2)-induced extravasation. The previous report on the effects of both compounds in vitro against PLA2, together with the present in vivo results, support the idea that the inhibition of this enzyme probably constitutes their main mechanism of action.
