ABSTRACT
Diabetes has become the third largest killer to human life and health,and its development is closely related to the intestinal flora imbalance caused by series of consequences.So adjusting the structure of intestinal flora becomes a new idea for the treatment of diabetes.Traditional Chinese medicine (TCM) has good curative effect in prevention and treatment of diabetes,and improvement on the structure of intestinal flora may be one of its important mechanisms.The article reviewed the research progress on prevention and treatment of diabetes by TCM single components (berberine,phloridzin,rheinic acid,etc),TCM single prescription (essential oil from Cinnamomum cassia,flower stalk of Coptis chinensis,total coumarin of Feucedani Radix) and TCM priscriptions (Gegen Qinlian Decoction,Shengjiang Powder,Buzhong Yiqi Decoction,Huanglian Jiedu Decoction,Wenyang Yiqi Huoxue Compound,etc.) based on new targets in intestinal flora,so as to provide reference for the development of TCM for prevention and treatment of diabetes.

ABSTRACT
A high-performance liquid chromatographic method was applied to the determination of gamabufotalin, telocinobufagin, bufotalin, cinobufotalin, bufalin, cinobufagin and resibufogenin in three traditional Chinese medicinal preparations containing ChanSu. The compounds were separated on a YMC-C18 column (250 x 4.6 mm, 5 um) with a gradient of acetonitrile and 0.3% aqueous acetic acid (v/v) at a flow rate of 0.8 mL min(-1) and detected at 296 nm. Complete separation was obtained within 35 min for the seven bufadienolides. The calibration curves showed good linearity (r2 > 0.999) within the test range. The recovery was 95.5% - 105.9%. The assay could simultaneously determine seven major bufadienolides of the three Chinese medicinal preparations of ChanSu in 35 min. The results obtained suggested that the developed HPLC assay could be comprehensively utilized for the quality control of the three traditional Chinese medicinal preparations of ChanSu used in the clinic.
