Physiological activities of Korean-grown garlic (GKG) and Chinese-grown garlic (GCG) were examined. Nitrite-scavenging activity (NSA), superoxide dismutase (SOD)-like activity, and electron-donating ability (EDA) of garlic extracted with water or with either 50% or 100% ethanol were measured. NSA was optimized at pH 1.2 and was highest in water and 50% ethanol extracts of both origins. SOD-like activities of water or 50% ethanol extracts from both Korea and China were 48.43-63.89% lower than those of 1% or 0.1% L-ascorbate solutions. SOD-like activities of GKG extracts were higher than those of GCG extracts, and those of water extracts of samples were highest. EDAs of GKG extracts were higher (32.51-43.74%) than those of GCG extracts, while those of both sample extracts were lower than 1% or 0.1% L-ascorbate solutions.
对韩国产大蒜（GKG）和中国产大蒜（GCG）的生理活性进行了检测。测定了用水或50%或100%乙醇提取的大蒜的亚硝酸盐清除活性（NSA）、超氧化物歧化酶（SOD）样活性和电子供体能力（EDA）。NSA在pH 1.2时达到最佳，且在两种产地大蒜的水提取物和50%乙醇提取物中最高。韩国和中国大蒜的水提取物或50%乙醇提取物的SOD样活性比1%或0.1%抗坏血酸溶液的低48.43 - 63.89%。GKG提取物的SOD样活性高于GCG提取物，且样品水提取物的SOD样活性最高。GKG提取物的EDA高于GCG提取物（32.51 - 43.74%），而两种样品提取物的EDA均低于1%或0.1%抗坏血酸溶液。
