Pharmacodynamics of Tongyushu Capsules in the Treatment of Dysmenorrhea / 中国药师

Objective:To observe the therapeutic effects of Tongyushu capsules on dysmenorrhea. Methods:With the intravenous injection of oxytocin in rats, the influence of Tongyushu capsules on rat uterine smooth muscle was observed in vivo. With the intraper-itoneal injection of oxytocin to replicate the mouse model of dysmenorrhea, the effect of Tongyushu capsules on dysmenorrhea was ob-served. Using acetic acid writhing method, the effect of relieving pain Tongyushu capsules in mice was observed. By the method of ear swelling induced by xylene in mice, the anti-inflammatory effect of Tongyushu capsules was observed. By the method of ice water bath and subcutaneous injection of adrenaline, the influence of Tongyushu capsules on the acute blood stasis model in rats was observed. Results:Compared with those of the model group, the contraction of uterine smooth muscle of the groups treated with Tongyushu cap-sules at various dosage was decreased obviously (P<0. 05), the number of body torsion reaction induced by oxytocin and acetic acid in mice was obviously decreased in 15 min (P<0. 05), the degree of ear swelling in mice treated with Tongyushu capsules was signifi-cantly reduced (P<0. 05), and the whole blood viscosity, plasma viscosity, hematokrit, erythrocyte sedimentation rate and erythro-cyte electrophoresis time were significantly decreased (P<0. 05). Conclusion:Tongyushu capsules have obvious effects of the inhibi-tion of excessive contraction of uterine smooth muscle, dysmenorrhea alleviation, anti-inflammation and relieving pain, which show good therapeutic effect on dysmenorrhea.

Influence of 70% ethanol extract from Huanglian Jiedu Decoction on expression of S180 tumor cell apoptosis factor in MDR model mice / 中华中医药杂志

Objective: To observe the effect of 70% ethanol extract from Huanglian Jiedu Decoction on expression of S180 tumor cell apoptosis factor in MDR model mice, and to research the molecule biology base fot directing clinic. Methods: simulate Clinic PFC project was simulated, the mice model of multi-drug resistance of S180 tumour cell was established. 70% Ethanol extract from Huanglian Jiedu Decoction were given for 10 days. The flow cytometry was used to observe Fas, Trail, CD54.,et al. Resluts: 70% Ethanol extract from Huanglian Jiedu Decoction can increase expression rate of Fas, Trail and improve apoptosis of S180 cell, at the same time it can decrease expression of CD54.Conclusions: 70% Ethanol extract from Huanglian Jiedu Decoction improve high level expression of apoptosis factor, and it maybe one of pass reverse multi-drug resistance of tumour.

Studies on chemical constituents from fruit of Crataegus pinnatifida / 中草药

Object To look for the proprietary constituent and the constituents with blood lipid regulating effect from the dried fruit of Crataegus pinnatifida Bge var major N E Br Methods Various column chromatographic techniques were employed for isolation and purification of the constituents UV, IR, EI MS, FAB MS, 1HNMR, 13 CNMR, HMBC, HMQC and 13 CGATE were used to identify the structure of the isolated constituents Results Six compounds were isolated from the fruit of C pinnatifida They were identified as 5, 7, 4′ trihydroxy flavone 8 C ? L rhamnopyranosyl (1→2) ? D glucopyranoside, i e vitexin rhamnoside (Ⅰ), hyperoside (Ⅱ), citric acid (Ⅲ), vitexin (Ⅳ), quercetin (Ⅴ), ursolic acid (Ⅵ) Conclusion Compound Ⅰ is a proprietary constituent in the fruit of C pinnalifida, which was obtained from this plant for the first time Compound Ⅱ is a main constituent with blood lipid reducing effect in flavonoids

Determination of lcariin in Bushenning Capsules by HPLC / 中成药

Objective: To establish a RP-HPLC method for the determination of icariin in Bushenning Capsules. Methods: The sample was prepared by water extraction-purfication through polyamide column. The determination was carried out on C 18 ODS column with mobile phase of acetonirile-water (23∶77), and detection wavelength at 270nm according to the external standard method.Results: The icariin sample size showed a good linear relationship at the range of 0.12-1.91ug and correlation coefficient was 0.9999. The average recovery of the added sample was 99.21%(n=5) and RSD was 1.79%. The RSD in a duplicate test was 2.18%.Conclusion: The method is simple, accurate, reproducibe and can be used for content determination of icariin of icariin of Bushenning Capsules.

Determination of Flavonoids in Fructus Crataegi by Colorimetry / 中成药

Objective: To establish a new method and limit of detection for Flavonoids content in Fructus Crataegi. Methods: Flavonoids in Fructus Crataegi in 10 regions was determined by colorimetry. Results: Content of Flavonoids in samples selected from 10 regions ranged 0.84%～3.62%. Content of hyperoside by colorimetry is correlative to that by HPLC. Conclusion: The method is simple, quick and reproducible. Flavonoid content in Fructus Crataegi was designed no less than 1.0%, extraction must be performed under 60?C and dried to constant weight for 6 hours.

Study on quality standards for Shimingbao Granules / 中成药

Objective: To establish the quality control standards for Shimingbao Granules.Methods:Radix Angelical Sinensis, Cortex Phellodendri and Pericarpium Citri Reticulatae in granules were identified by TLC. The content of paeoniflorin in Shimingbao Granules was determined by HPLC with external standard. Results:The average recovery was 97.54% and RSD was 1.7%( n =5). The RSD in a duplicate test was 1.7%( n =5). Conclusion: These methods are simple, accurate and specific and can be used for the quality control of Shimingbao Granules.
