Ich is developed with partial oxidation. Adding flowers, herbs or fruits to tea is utilised in producing scented tea. Prior investigation reported that Vietnamese tea contained BMS-986094 In Vivo catechin and catechin derivatives at comparable levels with these obtained from China, Japan and Australia [14]. Current case-control research have indicated frequent consumption of Vietnamese tea might have good impacts upon Vietnamese adults with variety 2 diabetes [15] and men with prostate cancer [16]. Beyond these, information about bioactive phenolic contents plus the potential health-promoting properties of Vietnamese tea are extremely limited, when those in the Chinese and Japanese have already been nicely recorded. The aim of this study was to quantitatively recognize phenolic, carotenoid and saccharide composition in diverse teas manufactured in Vietnam. Also, two herbal teas, which includes an artichoke tea and a refreshing tea ready from Senna obtusifolia, Glycyrrhiza uralensis and Sophora japonica, have been included inside the study. Attempts to analyze these constituents in teas have been produced to get a improved understanding of phytochemical composition and how these constituents contribute to the health positive aspects of tea consumption. two. Materials and Methods two.1. Chemical compounds and Reagents Analytical phenolic standards (caffeic acid, cinnamic acid, chlorogenic acid, daidzein, (-)epicatechin, ferulic acid, gallic acid, genistein, hesperetin, p-coumaric acid, p-hydroxybenzoic acid, kaempferol, phloretin, procyanidin A2, procyanidin B2, protocatechuic acid, quercetin, quercetin-3-O-glucoside, quercetin 3-O-galactoside, resveratrol, rutin, syringic acid and vanillic acid) had been obtained from Sigma-Aldrich (St. Louis, MO, USA). The (+)-catechin hydrate, cyanidin chloride and delphinidin chloride were bought from Cayman Chemical compounds (Ann Arbor, MI, USA). Acacetin, apigenin, luteolin, LCMS-grade methanol, acetone (ACS grade), naringenin and naringenin chalcone have been bought from Fisher Scientific (Pittsburgh, PA, USA). Ultra-pure water (using a resistivity of 18 M.cm plus a TOC level five ppb) for each of the experiments was prepared from a Milli-Q purification program (Millipore, MA, USA). two.two. Tea Samples Seven Vietnamese and 3 U.S. merchandise had been used within the study (Table 1, Figure 1). The Vietnamese goods were bought from tea makers located in Vietnam, like two jasmine teas, two green teas, a single ML-SA1 References oolong tea, one particular refreshing tea and one artichoke tea. The U.S. teas (one particular decaffeinated black tea, one particular decaffeinated green tea and a single jasmine tea) had been obtained from local groceries in Lincoln, Nebraska, USA. All the samples had been stored in a freezer (-20 C) until evaluation.Molecules 2021, 26, x FOR PEER REVIEW3 of 13 Molecules 2021, 26,3 ofTable 1.
