Analgesic and anti-inflammatory activities of the methanol extract of Kalanchoe gracilis (L.) DC stem in mice.

In this study, we evaluated the analgesic effect of the methanol extract of Kalanchoe gracilis (MKGS) stem in animal models by inducing writhing response with acetic acid and conducting formalin test. The anti-inflammatory effect of MKGS was also estimated on mice with lambda-carrageenan induced paw edema model. In order to investigate the anti-inflammatory mechanism of MKGS, we analyzed the activities of glutathione peroxidase (GPx) and glutathione reductase (GRx) in the liver, and the levels of interleukin-1beta (IL-1beta), tumor necrosis factor (TNF-alpha), malondialdehyde (MDA) and nitric oxide (NO) in the edema paw tissue.

Analysis of synthetic anti-diabetic drugs in adulterated traditional Chinese medicines by high-performance capillary electrophoresis.

Four synthetic anti-diabetic drugs, acetohexamide (ACE), chlorpropamide (CHL), glibenclamide (GLI) and tolbutamide (TOL), which can be found as adulterants in traditional Chinese medicines (TCMs) were assayed simultaneously using high-performance capillary electrophoresis (HPCE) in 4 min with UV detection at 200 nm. The electrolyte was a buffer solution containing 100 mM phosphate buffer (NaH2PO4/Na2B4O7, pH 7.5).
