Gynostemma pentaphyllum (Thunb.) tea was used in Vietnamese folk medicine as anti-diabetic agent.
OBJECTIVE
This study was aimed to investigate the inhibitory activities of fractions and constituents isolated from Gynostemma pentaphyllum on protein tyrosine phosphatase 1B (PTP1B) since it
Protein tyrosine phosphatase 1B (PTP1B) is a key factor in the negative regulation of insulin pathway and a promising target for treatment of diabetes and obesity. Herein, the sapogenin 2b, prepared from the natural triterpene saponin 1b, was modified at 3-position to establish the dammarane
Protein tyrosine phosphatase 1B (PTP1B) is an important factor in non-insulin-dependent diabetes mellitus (type-2 diabetes), and a promising target for treatment of diabetes and obesity. Therefore, the aim of this study is to investigate the inhibitory activities of constituents (three new together

Jiaogulan (Gynostemma pentaphyllum) has been widely used as a herbal tea, dietary supplement, and vegetable in Asian countries. In this study, six new gypenosides (1-6) were isolated from the aerial parts of G. pentaphyllum. Their molecular structures were elucidated through spectroscopic analysis
This study was conducted to evaluate the antihyperglycemic effect of an extract of Gynostemma pentaphyllum Makino, containing standardized concentrations of gypenosides, in C57BL/KSJ-db/db mice. For 5 weeks, animals were provided a standard AIN-76 diet (normal control) with rosiglitazone (0.005%,
BACKGROUND
To evaluate the safety of standardized extract of Gynostemma pentaphyllum in rats.
METHODS
The water extract of Gynostemma pentaphyllum was prepared and standardized, the dry powder yielded 6% gypenosides. In the acute oral toxicity test, the single oral dose of 5000 mg/kg of Gynostemma
