芍药药用的炮制研究

测试结果表明:芍药根茎部芍药甙、丹皮酚、苯甲酸的含量低,属质次部位;赤白芍中主成分基本相同,但含量有显著差异,应区分药用;白芍以直接刮去外皮不经水煮为佳。

Isolation and Characterization of Anthocyanins in Four Varieties of Vigna subterranea (Fabaceae)

By chromatographic methods (HPLC, TLC) coupled with spectral methods (LC-MS, TLC-MS) and chemical revelation tests, anthocyanins from four Vigna subterranea varieties (M4, D3, KVS350, KVS97) were isolated and identified as malvidin 3-O-β-D-glucopyranoside, paeonidin-3-O-β-D-glucopyranoside, petunidin-3-O-β-D-glucopyranoside, cyanidin 3-O-β-D-glucopyranoside, del- pinidin-3-O-β-D-glucopyranoside.

无糖型养胃颗粒的稳定性考察

目的 有糖型养胃颗粒改制成无糖型养胃颗粒后 ,对改制后的制剂在高温干热、恒温恒湿、留样考察 3个方面进行了质量稳定性考察。方法 用HPLC法测定养胃颗粒的芍药甙含量 ,按《2 0 0 2年版中国药典》对其他各项考察指标进行测定。 结果 该产品的含量、吸湿性 ,软化 ,粒度 ,溶化性 ,pH值和卫生学在考察期内基本无变化。
