Effects of a Korean herbal formulation, Silsosangami, consisting of seven medicinal herbs, and its seven herbs on endotoxin-induced experimental thrombosis in rats

A traditional Korean medicine, Silsosangami (SSG), consisting of seven different herbs of Typhae Pollen, Pteropi Faeces, Paeoniae Radicis rubra, Cnidii Rhizoma, Persicae Semen, Carthami Flos and Curcumae Tuber, has been reported to have a hypolipidemic effect in human subjects. In the present study, the inhibitory effects of SSG on a thrombosis in rats, induced by endotoxin treatment were examined. The anti-thrombic properties of SSG were also investigated with respect to blood parameters. The extracts of SSG and five of the seven herbs, except Cnidii Rhizoma and Carthami Flos, inhibited both endotoxin-induced disseminated intravascular coagulation (DIC) and thrombosis in rats. The extract also inhibited the endotoxin-induced decrease in blood platelets and fibrinogen, and the endotoxin-induced increase in fibrin degradation products (FDP) on disseminated intravascular coagulation in normal rats. In conclusion, the artificially induced, protective effects of SSG on ischemic infarction might be related to their inhibitory effects on DIC, platelet coagulation and thrombotic action.     

High performance liquid chromatographic fingerprint evaluation of the quinolizidine alkaloids from commercial Radix Sophorae Flavescentis

Fifteen commercial samples of Radix Sophorae Flavescentis were collected from different parts of China. HPLC analysis showed that the commercial samples all contained quinolizidine alkaloids and a total of nine chromatographic peaks were identified by referring to standard compounds, HPLC/MS analysis and comparison of the physicochemical data of the isolated peak with the literature. The contents of the major alkaloids were determined and the ratio of the major alkaloids contents was shown to be correlated with their source of origin. The commercial samples from China gave a distinct HPLC pattern showing the main alkaloids contents. The sample preparations were researched and the extraction conditions of the alkaloids were optimized. Reproducible HPLC fingerprints can be obtained for the quinolizidine alkaloids under the well-controlled extraction conditions. The HPLC fingerprint analysis method is suitable for the quality control of the Radix Sophorae Flavescentis and the standardization of phytomedicines.     

study of substance changes in flowers ofpueraria thunbergiana benth. during storage

Puerariae Flos is a traditional herbal medicine that has long been used as a treatment for colds, diabetes, and hangovers. The herbal medicine contains a wide variety of isoflavones such as kakkalide, tectoridin, and tectorigenin. This study demonstrates that the substances undergo a certain degree of change depending on the storage period by the method of HPLC and 13C-NMR, and that the HPLC analysis can be used to determine the freshness of Puerariae Flos.
