“…[15] Related studies have confirmed that Coreopsis tinctoria has beneficial effects for human health, such as antioxidant and antineurotoxic activities. [16] Furthermore, it has been reported that Coreopsis tinctoria has antidiabetic [17] and antioxidant [18] activities due to its flavonoid components. In this study, we focused on the antioxidant activity of anthocyanins from Coreopsis tinctoria (AC) and provided useful information for the development and the utilization of Coreopsis tinctoria.…”

Anthocyanins (AC) from Coreopsis tinctoria possesses strong antioxidant properties, while the effects of AC on cells damage induced by reactive oxygen species (ROS) in diabetes mellitus diseases progression have not been reported. The present study was carried out to evaluate the protective property of AC against cellular oxidative stress with an experimental model, H2O2‐exposed MIN6 cells. AC could reverse the decrease of cell viability induced by H2O2 and efficiently suppressed cellular ROS production and cell apoptosis. In addition, Real‐time PCR and Western blot analyses indicated that AC could protect MIN6 cells against oxidative injury through increasing the translocation of Nrf2 into nuclear, decreasing the phosphorylation level of p38 and up‐regulating the protein expression of antioxidant enzyme (SOD1, SOD2 and CAT). Thus, this study provides evidence to support the beneficial effect of AC in inhibiting MIN6 cells from H2O2‐induced oxidative injury.

“…The results showed that the contents in different parts of C. tinctoria and C. morifolium samples were greatly variant. It was noticed that flavanomarein (3) and marein (8) were two most abundant components in C. tinctoria flower samples, which occupied for >54% of all investigated compounds in each flower sample (Table 4). Other flavonoids and caffeoylquinic acids (CQAs) were also considered as the major components in C. tinctoria, consisting of taxifolin-7-O-glucoside (1), chlorogenic acid (2), quercetagetin-7-O-glucoside (5), isookanin (6), 5,7,3 ,5tetrahydroxy-7-O-glucoside (7), 3,5-dicaffeoylquinic acid (9), coreopsin (10), okanin (11).…”

Coreopsis tinctoria, also called "snow chrysanthemum" in China, is a flower tea material that has been reported to possess excellent pharmacological properties such as antioxidant and antidiabetic activities. The chemical characteristics of different parts (flowers, buds, seeds, stems, and leaves) of C. tinctoria were investigated based on microwave-assisted extraction and the simultaneous determination of 13 major active compounds by high-performance liquid chromatography, including taxifolin-7-O-glucoside, chlorogenic acid, (R/S)-flavanomarein, isocoreopsin, quercetagetin-7-O-glucoside, isookanin, 5,7,3',5'-tetrahydroxyflavanone-7-O-glucoside, marein, 3,5-dicaffeoylquinic acid, coreopsin, okanin, 5,7,3',5'-tetrahydroxyflavanone, and N(1) ,N(5) ,N(10) ,N(14) -tetra-p-coumaroylspermine. Chemometric analysis based on the contents of investigated compounds from 13 samples showed that C. tinctoria and the related flower tea materials, Chrysanthemum morifolium cv "Hangju" and "Gongju," were in different clusters, and different parts (flowers, buds, seeds, stems, and leaves) of C. tinctoria were obviously different. This study is helpful for the quality control and pharmacological evaluation of different parts from C. tinctoria and its related products.

“…It is well known that tea infusion, as a popular beverage, have been found to be many functions, especially antioxidant, which has found to be related with their chemical constituents, mainly including tea polyphenols, volatiles, water-soluble polysaccharides (Ahmed & Baral, 2011;Dreosti 2000;Quan et al, 2011;Wang, Xi, Guo, Wang, & Shen, 2015). However, to date, the researches on rose tea infusion have mainly focused on polyphenols and their antioxidant (Jamali et al, 2016;Vinokur et al, 2006;Zeng, Deng, Lv, & Peng, 2014;Zhang et al, 2014).…”

Rose tea is a kind of popular beverage in many Asian countries. In this study, the contents of volatiles, polysaccharides and total polyphenols in three species of Chinese rose tea infusions [Kuishui Rose (KSR), Pinying Rose (PYR) and Jinbian Rose (JBR)] were determined, respectively. Meantime, the volatiles from those three tea infusions were analyzed by GC‐MS, and their antioxidant activities were tested by 1,1‐diphenyl‐2‐picrylhydrazyl radical scavenging assay. As results, 17, 15, and 20 components were identified in their volatiles, respectively. The contents of volatiles, polysaccharides and total polyphenols, and the antioxidant activity of PYR tea infusion were higher than those of other two tea infusions. To elucidate the contributions of those main constituents in rose tea for its activity, correlation coefficients between them were analyzed, displaying that the polysaccharides and polyphenols are the main antioxidants in rose tea infusion, whose correlation coefficients were greater than 0.9. Practical applications As a kind of beverage with health care function, the activities and active ingredients of rose tea have mainly focused on polyphenols and their antioxidant so far. The current studies on the contents of volatiles, polysaccharides and total polyphenols and the antioxidant activities of rose tea infusions from three species in China could provide an useful comparison of the difference of antioxidant activities and constituents in those three rose teas and a basic data for quality control of rose tea.
