Montbretin A is an acylated flavonol glycoside that has been found in C. crocosmiiflora and has antidiabetic activity.1,2,3 It inhibits human pancreatic α-amylase and B. fibrisolvens amylase B (Kis = 8.1 and 1,600 nM, respectively).2 Montbretin A reduces blood glucose levels in Zucker diabetic fatty rats when administered at a dose of 7.4 mg/kg per day.4

计算结果:
工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
