RESUMEN
In this study, chemical compositions of fatty oils and bioactivity of crude extracts from Holotrichia diomphalia larvae as Chinese materia medica were investigated for the first time. The chemical compositions of the fatty oils were obtained by two different methods and determined by GC/MS. In total, the petroleum ether extract produced 21 compounds (96.3%) while the supercritical fluid extract produced six compounds (99.53%) for identification. The effect of petroleum ether and other crude extracts on Pyricularia oryzae was also examined. Results indicated that ethanol and petroleum ether extracts had excellent antifungal activities. These findings demonstrated that fatty oils from H. diomphalia larvae had great potential to be used as a source for natural health products.

OBJECTIVE: To study the anticancer activity of the Clematis manshrica saponins in vivo. METHOD: Anticancer activities were tested in mice with experimental tumor (S180, HepA and P388) in vivo. RESULT: The Clematis manshrica saponins showed a significant anticancer activities on Sarcoma-180, HepA and P388 implanted in mice. In S180 sarcoma, the average tumor inhibition rates were 42.78%, 52.06% and 58.25% (P < 0.05-0.01) respectively; The mean inhibition rates were 37.44%, 52.05% and 59.36% (P < 0.05-0.001) in Hep A tumor separately; while in P388 tumor, the mean inhibition rates were 34.50%, 46.78% and 54.39% (P < 0.05-0.01), respectively. CONCLUSION: The results indicate that Clematis manshrica has obvious antitumor effects against various transplanted tumor in mice.
