Modern research progress of traditional Chinese medicine Paeoniae Radix Alba and prediction of its Q-markers / 中国中药杂志

Paeoniae Radix Alba is the dried root of Paeonia lactiflora, which was first recorded in the Shennong's Classic of Materia Medica and listed as the top grade. It is a common blood-tonifying herb, and its chemical components are mainly monoterpenes and their glycosides, triterpenes, flavonoids and so on. Modern research has demonstrated that Paeoniae Radix Alba has the activities of anti-inflammation, pain easing, liver protection, and anti-oxidation, and thus it is widely used in clinical practice and has broad development prospects. In this paper, the research progress on the chemical composition, pharmacological effects, and quality control of Paeoniae Radix Alba were summarized. On this basis, the Q-markers of Paeoniae Radix Alba were predicted from the aspects of mass transfer and traceability, chemical composition specificity, and availability and measurability of chemical components, which will provide a scientific basis for the quality evaluation of Paeoniae Radix Alba.

Simultaneous determination of five saponins in Bupleuri Radix by HPLC-DAD dual wavelength method / 中国中药杂志

Epoxy ether type and isophthalene type saponin are the main saponins of Bupleurum chinense. However,due to the difference of their UV spectrum,there is no quantitative method for simultaneous determination of these two kinds of saponins. In this paper,a dual-wavelength high performance liquid chromatography(HPLC) was developed for simultaneous determination of five saponins in epoxidized ether(saikosaponin a,c,d) and isosorbide type(saikosaponin b1,b2). The mobile phase was eluted with acetonitrile-water(0.1% phosphoric acid) gradient at a column temperature of 30 °C and a flow rate of 1.0 mL·min⁻¹. The detection wavelengths were 208 nm for saikosaponins a,c, and d, and 254 nm for saikosaponins b₁ and b₂. The results showed that the separation of five kinds of saikosaponin was good, with the linear range of 9.70-1 935.00(=0.999 4),8.20-1 380.00(=0.999 3),6.90-1 640.00(=0.999 0),5.25-630.00(=0.999 4), and 5.15-618.00 mg·L⁻¹(=0.999 5), respectively. The average recoveries were 97.70%-100.2% and the RSD was less than 3%(=6). The method is simple,rapid and reproducible. It can be used for the determination of five kinds of saikosaponins in B. chinense.

Effect of Jin’s Three-needle Scalp Electroacupuncture on Cyt-c and Caspase-3 Expressions in the Cerebral Cortex in Intrauterine Distress-induced HIBDRats / 上海针灸杂志

ObjectiveTo investigate the effect of jin’s three-needle scalp electroacupuncture on Cyt-c and Caspase-3 expressions in the cerebral cortex in Intrauterine distress-induced HIBD rats and reveal the mechanism of its protective action on the brain. MethodThe abdomen was incised in a female SD rat at 21 days of pregnancy. Bilateral uterine horn blood vessels were tightly clamped with a hemostat for five minutes. An infant rat was then taken out by a cesarean section. A rat model of hypoxic-ischemic brain damage was confirmed by the use of a behavior test and braintissue sections. The rats were randomized into model and acupuncture groups. The model group was not needled. Acupuncture groups 1, 2, 3 and 4 began to be needled at 3, 5, 7 and 14 days after birth, respectively. Acupuncture treatment was given for seven consecutive days. The normal control group was naturally delivered, not used to make a model and not needled. All groups of rats were decapitated to take the brain tissue at 21 daysafter birth. Cyt-c and Caspase-3 expressions in the cerebral cortex were detected.ResultCyt-c optical density value decreased somewhat in the four acupuncture groups; there was a statistically significant difference between acupuncture group 1 or 2 and the modelgroup (P<0.05). Caspase-3 expression was significantly down-regulated in acupuncture group 1; there was a statistically significant difference compared with the model group (P<0.05).ConclusionThe protective effect of acupuncture beginning at 3 days after birthon the brain is related to the down-regulation of Cyt-c and Caspase-3 expressions in intrauterine distress-induced HIBD rats.
