摘要： Bibenzyls are one of the most essential natural ingredients for genus Bulbophyllum owing to various biological activities. Two bibenzyls (batatasin III and cirrhopetalidin) were first separated and elucidated from the stems of Bulbophyllum taeniophyllum, as well as used as standards for HPLC determination. Furthermore, the developed method was validated by performing with linearity, LODs, LOQs, precision, stability, repeatability and recovery. Then a simple and reliable HPLC-VWD method was adopted for simultaneous separation and quantitation of both analytes. In addition, the DPPH assay demonstrated that only cirrhopetalidin showed potent DPPH free radicalscavenging activity.
