Citrostadienol was isolated from the fruits of Schizandra chinensis Baill. (Schizandraceae) by silica gel chromatography and assigned fully by spectroscopic analyses ((I)H-(I)H COSY, HMQC and HMBC). It demonstrated higher inhibition activity on classical complement pathway (IC50, 4.6 x 10-8M) than previously reported active steroids.
