Abstract
Citrostadienol was isolated from the fruits of Schizandra chinensis Baill: (Schizandraceae) by silica gel chromatography and assigned fully by spectroscopic analyses (1H-1H COSY: HMQC and HMBC). It demonstrated higher inhibition activity on classical complement pathway (IC50, 4.6 × 10−8M) than previously reported active steroids.
