The result shows that when the weight ratio of Tx 6 to C 4H 9OH is 4∶1,the W/O microemulsion system has stabilizing and extensive regions, and the system is insensitive to the values of pH and in the range of room temperature.In accordance with the theoretical value of HLB,the suitable value of HLB for Tx 6 and C 4H 9OH to compose microemulsion is greater than 9,less than or equal to 10.展开更多
One new Iriterpene saponin was isolated from Panaxjaponicus C. A. Meyer var major (Burk.) C. Y. Wu et K. M. Feng, and established as oleanolic acid 3-O-[β-D-glucopyranosyl-(1 →2)-β-D-glucuronopyranosyl-6'-O-n-...One new Iriterpene saponin was isolated from Panaxjaponicus C. A. Meyer var major (Burk.) C. Y. Wu et K. M. Feng, and established as oleanolic acid 3-O-[β-D-glucopyranosyl-(1 →2)-β-D-glucuronopyranosyl-6'-O-n-butyl ester] which showed mod- erate antitumor activities against the A2780 cells and OVCAR-3 cells. Its structure was established by means of spectral data, particularly NMR, including HSQC and HMBC techniques.展开更多
