RESUMO
To find novel functional beverages from folk teas, 33 species of frequently used non-Camellia tea (plants other than Camellia) were collected and compared with Camellia tea (green tea, pu-erh tea and black tea) for the first time. Data are reported here on the quantities of 20 free amino acids (FAAs) and three purine alkaloids (measured by UHPLC), total polyphenols (measured by Folin-Ciocalteu assay), and antioxidant activity (DPPH). The total amounts of FAAs in non-Camellia tea (0.62-18.99 mg/g) are generally less than that of Camellia tea (16.55-24.99 mg/g). However, for certain FAAs, the quantities were much higher in some non-Camellia teas, such as γ-aminobutyric acid in teas from Ampelopsis grossedentata, Isodon serra and Hibiscus sabdariffa. Interestingly, theanine was detected in tea from Potentilla fruticosa (1.16±0.81 mg/g). Furthermore, the content of polyphenols in teas from A. grossedentata, Acer tataricum subsp. ginnala are significantly higher than those from Camellia tea; teas from I. serra, Pistacia chinensis and A. tataricum subsp. ginnala have remarkable antioxidant activities similar to the activities from green tea (44.23 μg/mL). Purine alkaloids (caffeine, theobromine and theophylline) were not detected in non-Camellia teas. The investigation suggest some non-Camellia teas may be great functional natural products with potential for prevention of chronic diseases and aging, by providing with abundant polyphenols, antioxidants and specific FAAs.

This research ws carried out to construct a medicine screening system targeting at human promoter of CCR5. The gene Human promoter of CCR5 was inserted into the rebuilt vector pGL3-neo. The pGL3-neo-CCR5 plasmids were transfected into Jurkat cells (the cell line of acute T lymphocyte leukemia). The lasting transfected cells were screened by G418. After seven kinds of traditional Chinese medicine had acted separately on the lasting transfected cells for 16h, the expression levels of CCR5 promoter in the cells were detected. The results showed that the level of luciferase activity of Shuanghuanglian-injectio group was remarkably lower than that of control (P < 0.05), and the levels of luciferase activity of Chuanhuning group, Baical skullcap root group, and Milkvetch root group were remarkably higher than that of control (P < 0.01). Shuanghuanglian-injectio depressed the activity of the transfected CCR5 promoter in cells cultivated in vitro; Chuanhuning, Baical skullcap root and Milkvetch root boosted the activity of the transfected CCR5 promoter in cells cultivated in vitro. Thus a medicine screening system based on Human promoter of CCR5 was initially constructed.
