DE—dry extract; GAE—Gallic Acid Equivalent; CAE—Caffeic Acid Equivalent; QE—Quercetin Equivalent; CHi—methanol–acetone–water (3:1:1, v/v) extract of C. hissaricus; CHs—methanol–acetone–water (3:1:1, v/v) extract of C. hsingshangensis; CHi-1—water fraction of C. hissaricus, CHi-2—diethyl ether fraction of C. hissaricus, CHi-3—butanol fraction of C. hissaricus, CHi-4—ethyl acetate fraction of C. hissaricus; CHs-1—water fraction of C. hsingshangensis, CHs-2—diethyl ether fraction of C. hsingshangensis, CHs-3—butanol fraction of C. hsingshangensis, CHs-4—ethyl acetate fraction of C. hsingshangensis. Values were presented as mean ± standard deviation (n = 9). Statistical analysis: a—significantly different results compared to CHi; b—significantly different results compared to CHi-1; c—significantly different results compared to CHi-2; d—significantly different results compared to CHi-3; e—significantly different results compared to CHs; f—significantly different results compared to CHs-1; g—significantly different results compared to CHs-2; h—significantly different results compared to CHs-3; i—significantly different results compared to CHs-4; One-Way ANOVA test, followed by a Tukey’s multiple comparison test, p < 0.05.
