The principal component analysis loading plot of blueberries for individual anthocyanins explained over 95% of the total variance. In summary, the results of this study suggest that a strategic approach to blueberry production could elevate the phenolic content and antioxidant capacity of cultivated blueberry. PRACTICAL APPLICATION The highbush blueberry, a rich source of bioactive polyphenols, is a popular fruit. The microclimate of the production system of highbush blueberries affects the concentrations of antioxidative phenolic compounds such as anthocyanins. Therefore, discovering and applying the appropriate method of production for each blueberry cultivar could facilitate production of high-quality blueberries rich in phenolic antioxidants.Ginsenoside Rc is one of the cardinal bioactive components of Panax ginseng. The present study aimed to investigate whether ginsenoside Rc exerted protective effects against acute cold exposure-induced myocardial injury in rats. Forty rats were randomly assigned into four groups Control, model, ginsenoside Rc 10 mg/kg, and 20 mg/kg groups. Rats were intragastrically administrated with ginsenoside Rc (10, 20 mg/kg) or vehicle daily for 7 days. On the seventh day, all rats except the control group were exposed to low temperature. Cardiac function, myocardial enzyme activities, hemorheology, and inflammatory response were detected. Histopathological examination and apoptosis of cardiac tissues were performed. The expressions of silent information regulator 1 (SIRT1), B-cell lymphoma (Bcl-2), Bcl-2-associated X (Bax), procaspase-3, and the mRNA (messenger RNA) level of SIRT1 were measured by western blot and real-time quantitative polymerase chain reaction (PCR) analysis. Ginsenoside Rc significantly improved carcated that ginsenoside Rc could alleviate acute cold exposure-induced myocardial in
