The physiological characteristics of kiwi (Actinidia delicosa) fruit were analyzed, which inclued its nutritional composition, in vitro-antioxidant activities, and neuronal cell protective effects. The most abundant components of mineral, amino acid, and fatty acid were found to be potassium (K), glutamic acid, and a-linolenic acid, respectively. The major free sugars were fructose, glucose, and sucrose. In addition, ${\beta}$-carotene and vitamin C contents were $1.35{\mu}g/100mL$ and 29.21 mg/100 g, respectively. The 2,2'-azinobis-(3-ethylbenothiazline-6-sulfonic acid) (ABTS) radical-scavenging activity of the n-hexane fraction obtained from the kiwi extract was 10.52% at a concentration of $1000{\mu}g/mL$. The malondialdehyde (MDA) inhibition of the n-hexane fraction was found to increased in a dose-dependent manner. The intracellular reactive oxygen species (ROS) accumulation after hydrogen peroxide ($H_2O_2$) treatment of PC12 cells was significantly reduced in the presence of the n-hexane fraction compared to PC12 cells treated with $H_2O_2$ only. Moreover, in the a MTT assay, the n-hexane fraction showed in vitro-protective effects against $H_2O_2$-induced neurotoxicity.
