Abstract

The water extract of Biota orientalis showed a potent inhibitory effect on platelet activating factor (PAF) binding to rabbit platelets using [3 H]PAF as a ligand in our previous screening studies for Korean medicinal antagonists by the activitiy-guided purification studies. Another active compound, compound 1 (IC50 = 2.3 × 10-5M, 7.48 ± 2.11 µg/ml, n = 4) was isolated from the title plant. The chemical structure of compound 1 was elucidated as pinusolidic acid by chemical and spectrometric analyses
