Introduction: Gloriosae Superbae Radix is a crude drug employed in Thai herbal remedies for several ailments. Colchicine is known as an active constituent in the roots. It was reported that 7-11 mg. of colchicine may causes lethal effect in human. In Thai traditional medical practice, the roots must be treated prior use to prepare Thai herbal preparations. However, pre-treated method has not yet been well established in any literature. This study aimed to document the pre-treated method and to quantitatively compare the amount of colchicine both before and after pre-treated. Methods: Firstly, interviewing with Thai traditional medicine experts and document the pre-treated methods of Gloriosae Superbae Radix to conclude the 2 commonly used methods. Two pre-treated methods (roasting and burning) were chosen for further study. Colchicine in Gloriosae Superbae Radix from 8 sources were analyzed before and after pre-treat by High Performance Liquid Chromatography (HPLC). Results: After pre-treat by roasting and burning, amount of colchicine in root were significantly decreased by 40.61{\textpm}9.55\% (p=0.000) and 26.79{\textpm}10.89\% (p=0.001), respectively. Comparison of colchicine contents of samples after roasting and burning, the amount of colchicine decreased non statistically insignificantly (p=0.110). Conclusion: Pre-treats of Gloriosae Superbae Radix by roasting and burning had significantly reduce colchicine content. Both methods have been proven to be the effective ways in preparing certain potentially toxic crude drugs before using in compounding into Thai herbal remedies.

Context:M. pudica is a common plant found in moist waste ground, lawns, open plantations and weedy thickets. Aims: The fasting blood glucose levels (FBG) and hematological values of M. pudica aqueous(MPA) and hydro-ethanolic (MPHE) extract were evaluated in normal and streptozotocin (STZ)-induced diabetic rats. Materials and Methods: MPA and MPHE 125, 250 and 500 mg/kg body weight (b.w.) were administered orally and daily to the rats for 8 weeks. The FBG were determined weekly. Red blood cells (RBC), hemoglobin (HM. pudicab), hematocrit (Hct), platelet, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), white blood cells (WBC), lymphocytes, monocytes, neutrophils and eosinophil were evaluated. Results: MPA and MPHE had no effect on blood glucose levels in normal rats. All doses of all extracts showed significantly (p\<0.05) decreasing FBG in diabetic rats. Especially MPA at the dose of 250 mg/kg b.w. showed more potent significantly (p\<0.05) decreasing blood glucose levels than anti-diabetic drug glibenclamide at the end of experiment. All extracts had no effect on RBC, Hb, Hct, platelet, MCH, MCHC, lymphocytes, monocytes neutrophils and eosinophils. Surprisingly, the extracts were decreased WBC and MCV in diabetic rats. In addition, all of the extracts did not produce the alteration of blood cells structure in all rats. Conclusion: This study indicated that the extracts were hypoglycemic effect and improve hematological values in diabetes which confirms the traditional use of the plant.
