OBJECTIVE
To study the optimal conditions for extraction of polyphenols from Acer truncatum with microwave.
METHODS
Using ethanol solution as solvent, some factors which influenced extraction of polyphenols such as ethanol concentration, ratio of material to liquid, size of material, microwave
OBJECTIVE
To optimize a technical process for extracting the polyphenols that can inhibit fatty acid synthase by ethanol from the leaves of Acer truncatum.
METHODS
The extracting time, extracting temperature, extracting solvent and the ratio of solvent to raw material were studied by L16 (4(5))
OBJECTIVE
To study the dynamic variations of the contents of total polyphenols, flvonoids and chlorogenic acid from Acer truncatum leaves in different months, and their inhibitory activities on fatty acid synthase.
METHODS
Spectrophotometry was used to determine the contents of total polyphenols,
Polyphenols, including flavonoids, are the major components of the extracts from aceraceous plants. They possess remarkable antibacterial and antitumour activity. Our study focused on whether the inhibition of the bacterial type II fatty acid synthesis system is the mechanism for the antibacterial
