[Pharmacokinetic effect of combined administration on spinosin and ferulic acid in monarch drug Ziziphi Spinosae Semen kernel].
To study the pharmacokinetic effect of different combined administration with monarch drug Ziziphi Spinosae Semen on its main components in rats. Sprague-Dawley (SD) rats were randomly divided into Ziziphi Spinosae Semen group, Ziziphi Spinosae Semen-Fructus Schisandrae Chinensis group, Ziziphi spinosae Semen-Salviae Miltiorrhize Radix et Rhizoma group and Zaoren Ansheng prescription group. After oral administration, HPLC was eluted with the mobile phase of acetonitrle-0.03% phosphate acid water in a gradient mode. ⋯ The pharmacokinetic parameters of spinosin and ferulic acid were calculated by DAS 2. 0 software. Compared with Ziziphi Spinosae Semen group, Ziziphi Spinosae Semen-Fructus Schisandrae Chinensis group, Ziziphi Spinosae Semen-Salviae miltiorrhizae Radix et Rhizoma group showed a lower maximum plasma concentration (C(max)) and area under curve (AUC(0-t)) for spinosin and ferulic acid but higher clearance speed (CL/F); whereas the Zaoren Ansheng prescription group showed higher maximum plasma concentration (C(max)) and area under curve (AUC(0-t)) for spinosin and ferulic acid but lower clearance speed (CL/F). Compared with Ziziphi Spinosae Semen group, prescription group showed slower metabolism of spinosin and ferulic

[Traditional Chinese medicine pairs (III)--effect of extract of Ginseng Radix et Rhizoma and Puerariae Lobatae Radix on intestinal absorption in rats].
This study focused on the intestinal absorption of traditional Chinese medicines (TCM) to reveal the scientific connotation of the compatibility of TCM pairs. The single pass intestinal perfusion (SPIP) was used in rats to compare the absorption of single extracts from Puerariae Lobatae Radix, single extracts from Ginseng Radix et Rhizoma, combined extracts from Puerariae Lobatae Radix and Ginseng Radix et Rhizoma and Puerariae Lobatae Radix and Ginseng Radix et Rhizoma mixture in rats. ⋯ Specifically, the order of puerarin Ka and Papp values from high to low was Ginseng Radix et Rhizoma and Puerariae Lobatae Radix mixture > single extracts from Puerariae Lobatae Radix > combined extracts from Ginseng Radix et Rhizoma and Puerariae Lobatae Radix; the order of ginsenosides Ka and Papp values from high to low was Ginseng Radix et Rhizoma and Puerariae Lobatae Radix mixture > single extracts from Ginseng Radix et Rhizoma > combined extracts from Ginseng Radix et Rhizoma and Puerariae Lobatae Radix. The combined administration of Ginseng Radix et Rhizoma and Puerariae Lobatae Radix may improve the absorption in the intestinal tract.

[Influence of solvent and drug preparation time on Shuanghuanglian injections induce pseudo-allergic reaction].
Choosing the right solvent and timely use is the basis of rational drug use and the most direct and efficient way to improve the safety of traditional Chinese medicine injections. This study aimed to evaluate the influence of solvent and drug preparation time on Shuanghuanglian injection inducing pseudo-allergic reactions with mouse mode. The two tests were carried out: (1) Comparative experiment between different solvent: Shuanghuanglian injection preparation to the appropriate concentration with 0.9% sodium chloride injection and 5% dextrose injection, mixed with Evans blue, at one time intravenous injected into mice, 30 minutes later, the mouse ears vascular permeability were observed and compared. (2) Comparative experiment among different preparation time: placed 10 min, 2.5 h, 6 h and 24 h after Shuanghuanglian injection were prepared and then to detect the pseudo-allergic reactions in mice using the same methods as in (1). The results showed that there was no significant difference in the pseudo-allergic reactions in mice which induced by the same dose of Shuanghuanglian injection, respectively with 0.9% sodium chloride injection and 5% dextrose injection preparation, and with the extension of preparation time, the degree of pseudo-allergic reactions of Shuanghuanglian injection was gradually severe.

[Study on accumulation of polysaccharides and alcohol-soluble extracts contents of Dendrobium officinale leaves].
This paper revealed the accumulation regularity of polysaccharides and alcohol-soluble extracts contents of Dendrobium officinale leaves, which have provided basis for the development and utilization of the leaves. The polysaccharides and alcohol-soluble extracts contents of three D. officinale strains leaves collected in different growing periods were determined by phenol-sulfric acid method and hot-dip method respectively. The results showed that the content of polysaccharides in leaves was 4.45% -12.17%, and was about a quarter in stems. ⋯ The leaves at the vigorous growth stage with higher content of polysaccharides. The alcohol-soluble extracts were closely associated to the formation and germination of buds. The content of alcohol-soluble extracts peaked before sprout, and promoted the growth of new shoots.

[Study on contribution of main components in Guizhi Fuling capsule based on molecular imprinting technique and activity screening].
To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. ⋯ The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.
