Abstract

Five commercial botanical products (Shilianhua [SLH] tablets, Shiu Huo pills, Fenulyn, Bitter Melon, and Glucose Metabolic Support), available in the US market, with reported claims for regulation of metabolism were screened for their effect on body weight gain in high-fat diet-induced obese mice. Pilot results suggested that SLH tablets attenuated body weight gain, whereas Shiu Huo pills and Fenulyn tended to promote weight gain in the mice on the high-fat diet. To investigate the bioactive components in the SLH tablet, the wild SLH plant (Sinocrassula indica Berge) was collected from China and used to make a variety of extracts including aqueous extract, ethanol extract (SLH-E), and subfraction F100. In the study of metabolic activities, the extracts were administrated through food intake by incorporating them into the diet. A rigorous evaluation of the extracts on body weight was conducted in 2 animal models. The aqueous extract and SLH-E were tested in dietary obese mice, while F100 together with SLH-E was tested in KK-Ay mice, a genetic diabetic model. In the 12- to 16-week study, body weight was not significantly altered by the SLH extracts in the 2 animal models. The results suggest that neither the total extract nor the purified components from the SLH plant have a clear effect in the regulation of body weight. The weight reduction observed with the over-the-counter SLH tablet in the pilot studies may be secondary to other components in the tablet, but not from the SLH extract.
