          Abstract

          Dyslipidemia is an independent risk factor of cardiovascular diseases. The statins are a milestone in the primary and second prevention of cardiovascular diseases and significantly improved its prognosis. Along with the long-term treatment with statins in combination with other hypolipidemic drugs or alone, its safety has attracted a particular attention in clinic, such as the elevation of transaminase and rhabdomyolysis, which have raised an idea of developing the other types of lipid-lowering agents from botanic materials. Traditional Chinese medicine (TCM) has been used in clinical practice for more than 2000 years in China and showed some beneficial effects for human health and many diseases. Recently, many studies demonstrated a favorable effect of TCM for treating dyslipidemia; however, its mechanism remains unclear or totally unknown. The progress and perspective of studies on dyslipidemia with single Chinese herb and its monomers or effective extracts during the past 10 years are discussed in the present review.

            Ginsenosides chemistry, biosynthesis, analysis, and potential health effects.

            Ginsenosides are a special group of triterpenoid saponins that can be classified into two groups by the skeleton of their aglycones, namely dammarane- and oleanane-type. Ginsenosides are found nearly exclusively in Panax species (ginseng) and up to now more than 150 naturally occurring ginsenosides have been isolated from roots, leaves/stems, fruits, and/or flower heads of ginseng. Ginsenosides have been the target of a lot of research as they are believed to be the main active principles behind the claims of ginsengs efficacy. The potential health effects of ginsenosides that are discussed in this chapter include anticarcinogenic, immunomodulatory, anti-inflammatory, antiallergic, antiatherosclerotic, antihypertensive, and antidiabetic effects as well as antistress activity and effects on the central nervous system. Ginsensoides can be metabolized in the stomach (acid hydrolysis) and in the gastrointestinal tract (bacterial hydrolysis) or transformed to other ginsenosides by drying and steaming of ginseng to more bioavailable and bioactive ginsenosides. The metabolization and transformation of intact ginsenosides, which seems to play an important role for their potential health effects, are discussed. Qualitative and quantitative analytical techniques for the analysis of ginsenosides are important in relation to quality control of ginseng products and plant material and for the determination of the effects of processing of plant material as well as for the determination of the metabolism and bioavailability of ginsenosides. Analytical techniques for the analysis of ginsenosides that are described in this chapter are thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC) combined with various detectors, gas chromatography (GC), colorimetry, enzyme immunoassays (EIA), capillary electrophoresis (CE), nuclear magnetic resonance (NMR) spectroscopy, and spectrophotometric methods.

              Chronic effects of berberine on blood, liver glucolipid metabolism and liver PPARs expression in diabetic hyperlipidemic rats.

              Berberine is one of the main alkaloids of Rhizoma coptidis which has been used as a folk medicine to treat diabetes mellitus for more than 1400 years in China. To investigate the chronic effect of berberine on diabetic hyperlipidemic rats, fasted rats were intraperitoneally injected 35 mg/kg streptozotocin. Diabetic rats were admitted after 2 weeks and given a high-carbohydrate/high-fat diet to induce hyperlipidemia. The rats were divided into 7 groups at the end of week 16: normal and diabetic rats received no drug, 5 treatment groups were administered with either 75, 150, 300 mg/kg berberine, 100 mg/kg fenofibrate or 4 mg/kg rosiglitazone per day for 16 weeks, respectively. The blood glucose, hemoglobin A1c, lipid metabolic parameters and hepatic glycogen and triglyceride were measured, and histopathology and peroxisome proliferator-activated receptors (PPARs) alpha/delta/gamma expression of liver were determined by hematoxylin eosin and immunohistochemical staining. Berberine reduced diabetic rats' body weight, liver weight and liver to body weight ratio. Berberine restored the increased blood glucose, hemoglobin A1c, total cholesterol, triglyceride, low density lipoprotein-cholesterol, apolipoprotein B and the decreased high density lipoprotein-cholesterol, apolipoprotein AI levels in diabetic rats to near the control ones. Berberine alleviated the pathological progression of liver and reverted the increased hepatic glycogen and triglyceride to near the control levels. Berberine increased PPARalpha/delta expression and reduced PPARgamma expression in liver of diabetic rat to near the control ones. Berberine improved glucolipid metabolism both in blood and liver in diabetic rats possibly through modulating the metabolic related PPARalpha/delta/gamma protein expression in liver.
