ABSTRACT
Obesity is a serious medical problem worldwide. As a holistic therapy, traditional Chinese medicine (TCM) may have a potential in obesity management. In this controlled trial, we evaluated the safety and effectiveness of xin-ju-xiao-gao-fang (XJXGF), a TCM herbal formulation, in 140 obese subjects over a 24-week period. The XJXGF formula mainly consists of rhubarb, coptis, semen cassia, and citrus aurantium. Subjects with body mass index (BMI) 28-40 kg/m(2) were recruited at 5 centers in China. We assessed the changes in subjects' body weight, its related parameters, and the reduction of insulin resistance (IR) after administration of XJXGF formula or low-dose XJXGF (10% of the XJXGF formula, as control). After 24-week treatment, among participants in the XJXGF formula group and low-dose XJXGF group, the mean ± SE changes in the body weight were -3.58 ± 0.48 and -1.91 ± 0.38 kg, respectively (p < 0.01). The changes in the IR-index of two groups were -2.65 ± 1.04 and -1.58 ± 1.3, respectively (p < 0 .05). There were no serious adverse events reported during the 24-week trial. Participants reported 7 minor adverse events, 4 in the XJXGF formula group and 3 in the low-dose XJXGF group (p = 0.578). Future studies are needed to investigate the clinical utility of this TCM formulation in the treatment of obese subjects.

Four new steroidal saponins, filiasparosides A-D (1-4), together with known aspafiliosides A (5) and B (6) were isolated from the roots of Asparagus filicinus. The structures of these new compounds were elucidated by detailed spectroscopic study and chemical analysis. Compounds 1-6 were cytotoxic against human lung carcinoma (A549) and breast adenocarcinoma (MCF-7) tumor cell lines with EC(50) values of 2.3-16.8 microg/mL. Compound 3 showed the most potent cytotoxicity, with EC(50) values of 2.3 and 3.0 microg/mL toward A549 and MCF-7 cell lines, respectively.

OBJECTIVE: To identify the volatile components in rat urine after oral administration of "Wu-Hu-Tang" (WHT). METHOD: GC-MS technique was applied to analyzing urine samples. RESULT: Eighteen components were detected in the WHT-treated rat urine other than the corresponding control. Among them, 14 components were identified, and 7 were also found in the extract of WHT. CONCLUSION: The above detected components might be derived from WHT, and some of them are effective components of WHT.
