Abstract:
Objective To investigate the chemical constituents in the whole plant of Clerodendrum canescens. Methods The compounds were isolated by column chromatography over silica gel or Sephadex LH-20 gel and their structures were elucidated by chemical and spectroscopic methods. Results Seven triterpenoids were isolated and identified as: lupeol (Ⅰ), ?-amyrin 3-undecanotate (Ⅱ), lupeol acetate (Ⅲ), lupeol 3-palmitate (Ⅳ), melastomic acid (Ⅴ), ?-amyrin acetate (Ⅵ), betulinic acid (Ⅶ), respectively. Conclusion Among those compounds, compound Ⅱ is a new one, while compounds Ⅳ-Ⅵ are isolated from the plants of Clerodendrum Linn. for the first time.
