    Tupistra chinensis Bak. is widely used as the common Chinese herbal medicine in the folk, belonging to Tupis genus of Liliaceae family. Usually its rhizome can be used as medicines for clearing heat and detoxification, as well as scattering silt convalescence and alleviating pain. Researchs have shown that the main chemical constituents of T. chinensis are saponins and flavonoids. It has multiple activities and good development prospect, which has been closely watched by researchers. This paper is presented as a review centered on the main chemical constituents pharmacological effects of T. chinensis, and it is useful to the further research and development of this plant.

    Nasturtium officinale is a leafy vegetable of the Brassicaceae family used as a home remedy or a medicinal plant due to anticancer, antioxidant, and hepatoprotective properties. The purpose of this study was to evaluate the effects of the water extract of N. officinale administered daily for 60 days at dose levels of 500 and 1000 mg/kg body weight in male Wistar rats. The effects on haematological and serum biochemical parameters were measured as indices of organ toxicity. The behaviour of rats was assessed in two animal models of anxiety, the open field test and the elevated plus-maze. After sixty-day intake of N. officinale water extract by gavage, the rats showed no significant changes in behavioural outcomes. The extract did not affect the biochemical profile related to serum lipid metabolism (TG, total cholesterol, HDL, and LDL) and markers of liver and kidney function (AST, ALT, total protein, albumin, and creatinine). However, a significant reduction in alkaline phosphatase (ALP) and BUN levels occurred in the treated groups. The extract did not affect WBC, RBC, Hb, HCT MCH, MCHC, MCV levels. It also produced no alteration in the body weight gain and relative weight of the organs. This study confirms that water extract of N. officinale administered up to the dose of 1000 mg/kg for long term is not likely to produce toxic effects on some organs or haematological and biochemical indices in rats.

    A preparation technology to obtain 5β-hydroxyacovenosigenin from roots of Streptocaulon juventas using ethanol refluxing and hydrochloric acid hydrolysis method

    1β-hydroxyacovenosigenin (HAG) is the main sterides structure of cardiac glycosides in the family of Asclepiadaceae and Scrophulariaceae. The objective of this study is to perform a practical method to prepare HAG from roots of Streptocaulon juventas (S. juventas) to arrange raw material to synthesize an active compound of TXA9. However, it’s quite hard to get HAG from roots of S. juventas easily. To obtain the HAG efficiently, two orthogonal experiments were designed to optimize the parameters of extraction and hydrolysis condition of S. juventas. A four-factor, three-level orthogonal extracting test was projected to confirm the extraction condition of S. juventas to obtain the total cardiac glycosides (CG). The optimal parameters were determined as extraction time of 3 h, extraction number of 2 times and ethanol (EtOH, 75%) to raw material of 10-fold, respectively. The content of CG was tested with the colorimetric method. To get more HAG, the other three-factor, three-level orthogonal hydrolysis of CG experiment was studied. With the HPLC to test the peak area of HAG, the CG was hydrolyzed with hydrochloric acid (HCl, 0.1 mol/L) at 70 ºC for 1.5 h and extracted with dichloromethane for three times after each reaction. The hydrolysis reaction numbers were intended to be four times. With the optimised extracting and hydrolysis method, a solution rich of HAG and other cardiac aglycones (CA) was obtained. The solution was concentrated and purified with silica gel and ODS. 4.45 g of purified HAG was acquired from 160 kg of roots of S. juventas after recrystallising with dichloromethane/ethyl acetate for several times. The technology has been validated; it shows good results in terms of easy operation, repeatability and high scientificity. It could be used to prepare large amount of HAG in the further research.
