Wines made from 3 spine grape (Vitis davidii Foex) genotypesJunzi 1# (JZ 1#), Junzi 2# (JZ 2#), and Liantang (LT)and Cherokee rose (Rosa laevigata Michx., CR) were evaluated for their phenolics composition and antioxidant activities by several assays, including 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS scavenging capacity, cupric ion reducing antioxidant capacity, and metal-chelating capacity). The results showed that CR wine had higher contents of total phenolics, total flavonoids, and oligomeric proanthocyanidins than the 3 spine grape genotype wines and Cabernet Sauvignon (CS) wine. Among the 3 varieties of spine grape wines, JZ 1# had higher contents than the 2 other genotypes. Moreover, the total monomeric anthocyanins in JZ 1# was about 4.5-fold higher than those in CS wine and CR wine. A significance analysis demonstrated that the antioxidant capacity (as measured by the ABTS scavenging capacity and cupric ion reducing antioxidant capacity) of CR wine was significantly higher than that of the control and spine grape wines. With respect to metal-chelating capacity, the CR wine was the strongest amongst all the wine samples tested, followed by JZ 1#. This indicates that CR and JZ 1# wines can potentially be considered as wild fruit wines with abundant phenolic compounds and antioxidant activities.
