ABSTRACT
Cancer is a major public health burden in both developed and developing countries. Plant-derived compounds have been an important source of several clinically useful anti-cancer agents including taxol, vinblastine, vincristine, the camptothecin derivatives, topotecan and irinotecan, and etoposide derived from epipodophyllotoxin are in clinical use all over the world. About 30 plant derived compounds have been isolated so far and are currently under clinical trials. Cancer chemopreventive agents, many of which are natural products, are capable of preventing or inhibiting the process of carcinogenesis. As with other pharmaceutical agents useful for disease prevention, a pharmacoeconomic analysis of a cancer chemopreventive formulation would need to be considered, and the composition of the formulation should improve over time. A number of promising new agents are in clinical development based on selective activity against cancer-related molecular targets, including flavopiridol, roscovitine, combretastatin A-4 phosphate , betulinic acid and silvestrol are in clinical or preclinical development.
ABSTRACT
Object To establish the method for quality control of Fushengkang Capsule. Methods Semen Livistonae Chinensis, Fructus Camptothecae Acuminatae and Rhizoma Curcumae in this capsule were identified by TLC. The content of camptothecine was determined by HPLC. Condition of HPLC was: Dikma Diamonsil C 18 column (250 mm? 4 6 mm, 5 ?m) the mobile phase was a mixture of methanol water (55∶45), the flow rate was 0 8 mL/min, and detection wavelength at 254 nm. Results The spots of TLC were clear and concentrative. There was a good linear relationship for camptothecine within the range of 0 050 6 - 0 253 0 ?g. The average recovery was 96 90%, RSD=1 74% (n=6). Conclusion This method is sensitive, accurate, reproducible and exclusive. It can be used for quality control of Fushengkang Capsule
