Abstract:

Fuzhuan Brick-Tea is a postfermented product with the hypoglycemic effect, which is prepared from the leaves of Camellia sinensis var. sinensis. However, the material basis associated with the hypoglycemic effect was not clear. The present research was designed to explore the hypoglycemic effect of extract/fractions from Fuzhuan Brick-Tea in streptozotocin-induced type II diabetic mice. Then an ultra-high pressure liquid chromatography along with quadrupole time of flight mass spectrometry was used to analyze the phytochemicals in Fuzhuan Brick-Tea fractions. As a result, the hypoglycemic and hypolipidemic effects were evidently observed from the serum biochemical indexes and liver pathological examination in type II diabetic mice. In addition, there were total of 20 major components including eight lysophosphatidylcholines (Lyso-PCs), five fatty acids, and seven novel theophylline derivatives tentatively identified in the active fraction from water extract. Therefore, these components were assumed to contribute partly to the hypoglycemic effect of Fuzhuan Brick-Tea. These findings also give the evidence that the Lyso-PCs, fatty acids, and novel theophylline derivatives in Fuzhuan Brick-Tea may provide benefits in ameliorating disorders of glucose and lipid metabolism. PRACTICAL APPLICATION: This study suggests that the Lyso-PCs, fatty acids, and novel theophylline derivatives in Fuzhuan Brick-Tea may provide benefits in ameliorating disorders of glucose and lipid metabolism. It can be taken as a beneficial diet additive or nutraceutical.
