sapogenin

Tigogenin was separated completely from the crude sapogenins by macroporous resin column chromatography,only simple solvent Ilelute was used in the column of the separate process.

用大孔树脂为吸附剂色谱方法在分离过程中仅需要简剂-Ⅱ,分离出一组分剑麻甙元占粗甙元比率高达70%以上。

After the dormancy in whole winter, the stem color would be changed into fulvous. 3 single lines with over 1% steroid sapogenin have been selected from those lines with near 1% steroid sapogenin.

利用筛选出苷量接近1%材料，选育出苷量超过1%株品系3个。
