BACKGROUND
Adinandra nitida Merr. ex. H.L. Li (Theaceae) is an indigenous plant in south China. Its leaves have been reported to have many curative effects such as reducing blood pressure, as well as antibacterial, antioxidant, and analgesic properties, which could be used in foods and
Extracts of Adinandra nitida leaves, known as Shiyacha in China, were analyzed by monolithic columns of capillary electrochromatography (CEC). To obtain good resolution within a short time, stepwise gradient elution of CEC was employed, and the effects of experimental parameters, such as the buffer,
OBJECTIVE
To established a novel HPLC-PAD method for the simultaneous determination of five compounds (camellianin A, camellianin B, apigenin, quercitrin, epicatechin) in leaves of Adinandra nitida.
METHODS
These compounds were effectively separated on a reversed-phase C18 column (4.6 mm x 250 mm,
Obesity is a worldwide epidemic contributing to a higher risk of developing maladies such as type 2 diabetes, heart disease, and cancer. Shiya tea (leaves of Adinandra nitida), a traditional Chinese tea, is widely consumed due to its palatable flavor and various curative effects, such as reducing
Leaves of Adinandra nitida constitute a kind of flavonoid-rich plant food. In this study, camellianin A, the main flavonoid in the leaves of Adinandra nitida,was prepared and identified by high performance liquid chromatography-photodiode array detector-electrospray ionization mass spectrometry
Consumption of plant foods has been negatively associated with the risk of developing chronic diseases, which is partly attributed to their rich and diverse phytochemicals. To promote the rational and effective application of Adinandra tea (Adinandra Jack), a traditional Chinese tea (Shiyacha)
