The extraction process and content examination were studied with the methods of orthogonal test and spectrophotometry compared with Rutin; then the total flavonoids from Ramulus Mori were extracted with the methods of phytochemistry and examined.

以芦丁为对照品，运用正交设计试验及分光光度法，对桑枝总黄酮(the total flavonoids from Ramulus Mori，RMTF)的提取工艺、含量测定进行了探索；然后，采用植物化学方法提取并定性检测桑枝总黄酮，进而开展动物降血糖药理试验。

Methods:(1) Silica column chromatography and LH-20 were used in phytochemistry study.(2) Based on the extraction ratio of arctiin, the best extraction procedure was acheived under the direction of L9(34) orthogonal experimental design. From 10 types of resins, the one with the maximal binding ability for Arctii was selected and silica-column choramatograpy was used in its seperation and purification procedure.(3) The animal diabetic experimental model in Wistar rats was established with streptozotocin and many biochemical factors were used to indicate the pharmacological effects of arctiin, including glycosylated hemoglobin, serum creatinine, seralbumin, monoxide nitrogen, glycerin trilaurate, cholesterol, HDL-ch, LDL-ch, Blood urea nitrogen, creatinine, SOD, ET, MDA, total Urine protein and albuminuria.
