摘要:

本实验以大豆胚芽为原料,香草醛- 高氯酸为显色剂、冰醋酸为溶剂,大豆皂苷Bb 为标准品,通过大豆皂苷苷元显色,在波长563nm 处测定吸光度,建立了苷元比色法测定大豆总皂苷的定量方法。实验证实该方法线性和稳定性可靠。

Abstract:

One major triterpenoid saponins were isolated from soybean hypocotyls and identified as soyasaponin Bb. The prepared soyasaponin Bb was used as authentic standard for colorimetric determination of soyasaponin content based on the aglycone moiety (soyasapogenol). The employed coloring reagent was vanillin-acetic acid and the determination was made at the wavelength of 563 nm. The results showed that the developed colorimetric assay method is simple, sensitive and relatively precise.

Key words: soyasapogenol, soyasaponin, colorimetric determination
