Secondary metabolites from Clerodendrum chinense[Reference: WebLink]

METHODS AND RESULTS:
Chemical studies carried out on Clerodendrum chinense yielded three new compounds including the steroid (22E, 24S)-Stigmasta-4,22,25-trien-3-one (1), the flavone glycoside 7, 8, 4′-trihydroxyflavone-6-O-β-D- glucuronopyranoside (2) and the epimeric neo-clerodane 14, 15-dihydro-15ξ- hydroxyclerodendrin A (3). Two acetylated derivatives of compound 3-, 2α-acetoxy-14, 15-dihydro-15ξ-hydroxyclerodendrin A (4) and 2α-acetoxy-14, 15-dihydro-15ξ-methoxyclerodendrin A (5) were also prepared, which have not been reported previously.
CONCLUSIONS:
The structure of each compound was elucidated by spectroscopic means.
