摘要:

目的:分析绞股蓝皂苷Gypenoside ⅩLⅥ的微生物转化产物。方法:利用益生菌德氏乳杆菌保加利亚亚种的脱脂牛奶培养基对Gypenoside ⅩLⅥ进行微生物转化,并利用液相色谱离子阱飞行时间串联质谱方法鉴定Gypenoside ⅩLⅥ的微生物转化产物。结果:Gypenoside ⅩLⅥ的微生物转化产物为绞股蓝皂苷Gypenoside L、Gypenoside LI、Damulin B 和Damulin A。结论:通过微生物转化方法可以获得更多天然产物活性成分。

Abstract:

Objective: This study aimed to analyze the microbial transformation products of gypenoside ⅩLⅥ. Methods:
Gypenoside ⅩLⅥ was transformed by the probiotics Lactobacillus delbrueckii subsp. bulgaricus grown in skim milk
medium. The transformation products were identified by high performance liquid chromatography-ion trap time of flight
(LCMS-IT-TOF) mass spectrometry. Results: The products were identified as gypenoside L, gypenoside LI, damulin B and
damulin A. Conclusion: More bioactive constituents from the natural product may be obtained by microbial transformation.

Key words: microbial transformation, Gynostemma pentaphyllum, gypenoside ⅩLⅥ, Lactobacillus delbrueckii subsp. bulgaricus
