Thin Layer Identification of Jiedu Shengxue Granules and Determination of Notoginsenoside R1 Content

[Objectives]To establish the quality standard of hospital preparation Jiedu Shengxue granules.[Methods]Scleromitrion diffusum and Prunella vulgaris in Jiedu Shengxue granules were qualitatively identified by thin layer chromatography(TLC).A high performance liquid chromatography(HPLC)was established to determine the content of notoginsenoside R1 in the granule.[Results]The traditional Chinese medicinal materials in Jiedu Shengxue granules could be identified by TLC,and the characteristic spots were stable and clear.Notoginsenoside R1 had a good linear relationship in the range of 10.45-104.5μg/mL,with an average recovery of 98.52%and RSD=2.36%.[Conclusions]TLC and HPLC,as the quality control methods of Jiedu Shengxue granules,have high accuracy and good repeatability,which lays a foundation for the quality control of this mixture.

Effect of Yisui Shengxue Granule (益髓生血颗粒) on the Oxidative Damage of Erythrocytes from Patients with Hemoglobin H Disease

Objective： To investigate the effect of Yisui Shengxue Granule （益髓生血颗粒, YSSXG）, a complex Chinese medicine, on the oxidative damage of erythrocytes from patients with hemoglobin H （HbH） disease. Methods： Twenty-two patients with HbH disease and 22 healthy volunteers were observed. YSSXG was given to patients with HbH disease for 3 months. Before and after the 3-month treatment, blood parameters [hemoglobin （Hb）, red blood cells （RBCs）, and reticulocyte percent （Ret）] were examined; inclusion bodies in erythrocytes were observed by transmission electron microscopy （TEM）; activities of antioxidant defense enzymes [superoxide dismutase （SOD）, glutathione peroxidase （GSH-Px）, and catalase （Cat）] and erythrocyte membrane malondialdehyde （MDA） concentrations were determined. Results： In patients with HbH disease, measured values of RBC and Hb obtained from the first to the third months after treatment with YSSXG were significantly higher than before treatment （P〈0.01）. Measured values of Ret from the second to the third months aftertreatment were significantly lower than before treatment （P〈0.05 and P〈0.01, respectively）. Prior to treatment with YSSXG, TEM images of RBCs showed the presence of numerous inclusion bodies. After treatment with YSSXG, the amount and volume of inclusion bodies decreased. Treatment with YSSXG also led to a significant increase in SOD activity （P〈0.01）, a decrease in Cat activity （P〈0.01）, and no significant differences in GSH-Px activity （P〉0.05） or MDA concentration （P〉0.05）. However, compared with the healthy counterparts, SOD, GSH-Px, and Cat activities presented at high levels （P〈0.01） both before and after treatment. Conclusions： YSSXG could improve the degree of hemolysis and anemia in patients with HbH disease. The mechanism may be related to its antioxidative effects, which could elevate the activity of total SOD in erythrocytes and efficiently inhibit the oxidative precipitation of β-globin chains.
