This study was carried out as a prerequisite to evaluate the therapeutic potential of Camellia varieties. The crude extracts of six different plants of green tea Camellia assamica and Camellia sinensis were tested against three Gram-positive and four Gram-negative bacteria using agar disk diffusion method at 50 mg/ml concentration. 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and dip...
This PDF was generated from an article on http://drhoffman.com/ © 2017 Ronald L. Hoffman MD, PC. All Rights Reserved | 1 Archeological evidence suggests that tea leaves steeped in boiling water were consumed as many as 5,000 years ago. Botanical evidence indicates that India and China were among the first countries to cultivate tea. Although the English are known for their love of tea, American...
Four triterpenes were isolated from a traditional Japanese tea product produced by anaerobic microbial fermentation of heated green tea leaves (Camellia sinensis). Two of the compounds were novel and characterized by spectroscopic investigation to be 13,26-epoxy-3β,11α-dihydroxyolean-12-one and 3β,11α,13β-trihydroxyolean-12-one. Two known triterpenes were identified as taraxastane-3β,20β-diol a...
Tea flavonoids and polyphenols are well known for their extraordinary antioxidant activity which is considered important for anti-aging processes in animals. This study evaluated the anti-wrinkle effects of three different kinds of tea (Camellia sinensis) water extracts (CSWEs) including green, white, and black teas using a photoaged hairless mouse model. Data showed that the CSWE-treatment gre...
Chen Q., Zhao J., Liu M., Cai J. (2008): Nondestructive identification of tea (Camellia sinensis L.) varieties using FT-NIR spectroscopy and pattern recognition. Czech J. Food Sci., 26: 360–367. Due to more and more tea varieties in the current tea market, rapid and accurate identification of tea (Camellia sinensis L.) varieties is crucial to the tea quality control. Fourier Transform Near-Infr...
This article includes experimental data on the identification of epigallocatechin-3-O-(3-O-methyl)-gallate (EGCG3''Me) by 2-dimensional (2D) proton (1H) NMR analysis and on the information of amino acid and catechin compound profiles by HPLC analysis in leaf extracts of various tea cultivars. These data are related to the research article "Metabolic phenotyping of various tea (Camellia sinensis...
Tea leaf (Camellia sinensis) is rich in catechins, which endow tea with various health benefits. There are more than ten catechin compounds in tea, among which epigallocatechingallate (EGCG) is the most abundant. Epidemiological studies on the association between tea consumption and the risk of breast cancer were summarized, and the inhibitory effects of tea catechins on breast cancer, with EGC...
About 75% of the estimated 2.5 milliontons of dried tea harvested annually in the world is manufactured as black tea. Black tea (Camellia sinensis) is one of the most widely popular nonalcoholic beverages consumed by over two-thirds of the world's population, due to its medicinal, refreshing and mild stimulating effects; besides the positive effects, studies have also shown that drinking tea ca...
Background and Purpose: Denture stomatitis is a chronic inflammation disease of the oral mucosa, which is specified by erythematous lesions mainly in the upper palate. Nystatin as a polyene, a class of antifungal agents, is one of the effective drugs to treat denture stomatitis. Considering the expansion of utilizing herbal drugs to cure many kinds of diseases, the present study was conducted t...
OBJECTIVE Epidemiological evidence has linked consumption of black tea, produced from Camellia sinensis, with a reduced risk of cardiovascular diseases. However, intervention studies on the effects of tea consumption on blood pressure (BP) have reported inconsistent results. Our objective was to conduct a systematic literature review with meta-analysis of controlled human intervention studies e...
