Plants of genus Cichorium are famous due to their therapeutic and medicinal properties. They are used as traditional medicine and edible food. To date, several scholars concentrated on compounds belonging to coumarins, flavonoids, sesquiterpenoids, triterpenoids, steroids, organic acids and other chemical constituents. Pharmacological effects such as photo-protective, hepatoprotective, anti-diabetic and lipid lowering, antioxidant, anti-inflammation, antifungal, antimalarial, increased bone mineral density, as well as vasorelaxant and antitumour activity were wildly reported. In this study, botanical resources, ethnopharmacological application, chemical constituents and bioactivities, as well as safety and toxicity of clinical applications of genus Cichorium were reviewed, which may provide a reliable basis for further development and utilization of Cichorium genetic resources.

To investigate the protective effects and possible mechanism of pomegranate flowers polyphenols (PFP) on liver function of rats with diabetes combining non-alcoholic fat liver diseases, diabetes combining nonalcoholic fat liver disease model rats were established with high calorie feeding and small dose intraperitoneal injection of streptozotocin (STZ). Model rats were randomly divided into: model group, metformin group, pomegranate flowers polyphenols low, medium and high dose group (75, 150 and 300 mg x kg(-1)). After four weeks treatment, the levels of FPG, blood fat profiles and serum insulin, ALT, AST levels, SOD and MDA in the liver and serum separately were analyzed with biochemical methods. Paraoxonase (PON1 and PON3) mRNA and protein expression in liver were checked by RT-PCR and immunohistochemical method. Pathological changes of the liver were observed. FPG, IRI, non-HDL-C and transaminase significantly reduced and HDL-C raised in the each PFP dose group; Furthermore, compared with model group, fat drops in liver cells significantly reduced, antioxidant ability enhanced, PON1 mRNA and protein expression level in liver increased significantly. The protective effects of PFP against diabetes combining non-alcoholic fat liver diseases rats might through the increase liver PON1 mRNA and protein expression further enhanced the body antioxidant capacity and reduced IRI so as to ameliorate the rat hepatic steatosis.

Protective effects of two different extracts of TSCA (total saponins from Cicer arietinum) were studied on kidney of T2DM rats. The diabetic model group was established with high calorie feeding and small dose injection of streptozotocin (STZ, 45 mg x kg(-1)). DM rats were randomly assigned to model group (feed with propylene glycol 1 mL/100 g), TSCA high dose group (300 mg x kg(-1)), TSCA low dose group (100 mg x kg(-1)) and normal control group (feed with propylene glycol 1 mL/100 g). After four weeks treatment with TSCA I and II, the levels of FPG FIns, BUN, Scr, ATII, ET-1, TXB2 and 6-keto-PGF1alpha in blood and the activities of SOD, GSH-PX and MDA in kidney were analyzed by biochemical methods. After four weeks treatment with TSCA II, the levels of FPG FIns, BUN, Scr, ATII and ET-1 were reduced significantly; and the ratios of TXB2 to 6-keto-PGF1alpha and SOD were effectively alleviated in TSCA II group. While there is no significant change on FPG and BUN in comparison to the rats treated with TSCA I, Scr, ATII, ET-I, GSH-PX and SOD were alleviated. The results suggest that TSCA II could be used to reduce FPG and FIns. According to the result of vasoactive substances index, TSCA II is more effective than TSCA I on renal protection of DM rats.

Due to the diversity and complexity, the change of chemical components in medicinal plant according to the time, cultivated varieties or ecological condition is difficult to recognize using traditional phytochemistry method. In order to analyze the pharmacodynamics material basis in Uighur medicinal plant Artemisia rupestris L. in an effective and comprehensive way, a plant metabolomics approach was established based on liquid chromatography-tandem mass spectrometry (LC-MS/MS). This study firstly focused on the effect of extraction solvents,redissolve solvents and ultrasonic time on the untargeted metabolomics, then the optimal preparation condition was selected according to metabolites coverage. After methodology validation, the approach was applied to acquire metabolic information in root, stem, branchlet, leaf and flower of Artemisia rupestris L. The results showed that the metabolome in flower was obviously different with the other organs. Coupling with multivariate statistical analysis, a batch of differential metabolites were picked out, in which 61 flavonoids, 97 rupestonic acid derivatives, 7 chlorogenic acids and 15 other compounds were primarily recognized according to the characteristic fragmentation rules of specific structure type and database retrieval. Additionally,the distribution characteristics of the above 180 differential metabolites was illustrated by cluster heat map. In conclusion,this study provided important information about the rational utilization of effective parts from Artemisia rupestris L.,and offered a novel strategy for quality control,variety improvement and reasonable development of medicinal plants.

RESULTS The optimal extraction process of Xuelian yishen formula was extraction time of 2 h， solid-liquid ratio of 1∶12， extracting for 3 times. Average comprehensive score of 3 validation tests was 96.40 points （RSD＝0.28%）， the deviation of which with predictive value was 0.98%. CONCLUSIONS The optimized extraction process is stable， feasible and reproducible， which can provide reference for the extraction process of Xuelian yishen formula.

In traditional Chinese medicine, Nitraria sibirica Pall. (Nitrariaceae) is used to treat hypertension. This study determined the effects of the total alkaloids of the leaves of Nitraria sibirica (NSTA) on blood pressure and albuminuria in mice treated with angiotensin II and a high-salt diet (ANG/HS). Adult mice were divided into three groups: control; infused with angiotensin II and fed a diet containing 4% NaCl (ANG/HS; and ANG/HS plus injection of NSTA (1 mg·kg(-1)·d(-1), i.p.). After treatment of these regimens, daily water and food intake, kidney weight, blood pressure, urinary albumin excretion, renal concentrations of inflammatory markers, including soluble intercellular adhesion molecule-1 (sICAM-1) and monocyte chemoattractant protein-1 (MCP-1), and the expression of renal fibrosis markers were determined. Compared to the control group, the ANG/HS group had higher blood pressure and urinary albumin excretion. Treatment with NSTA in ANG/HS mice for three weeks significantly reduced blood pressure and urinary albumin excretion. ANG/HS treatment caused elevated levels of sICAM-1 and MCP-1, as well as increased fibrosis markers. Concurrent treatment with ANG/HS and NSTA attenuated the levels and expression of renal inflammatory and fibrosis markers. Treatment with NSTA effectively reduces hypertension-induced albuminuria through the reduction of renal inflammatory and fibrosis markers.
