ABSTRACT
The antioxidant and anti-adipogenic activities of the water extract (WE) and methanol extract (ME) of the shell and kernel of Castanopsis cuspidata var. thunbergii (CCT) nuts were evaluated. The shell extracts showed higher DPPH and ABTS radical scavenging activities (RSAs) than did the kernel extracts. Furthermore, the RSA of the ME was higher than that of the WE, regardless of the part. The total phenolic contents (TPCs) of the ME of the shell and kernel were 71.38 and 10.56 mg gallic acid equivalent (GAE)/100 mg extract, respectively. The TPCs of the WE of the shell and kernel were 17.44 and 9.27 mg GAE/100 mg extract, respectively. The WE inhibited 3T3-L1 adipogenesis more effectively than did the ME, and the shell extracts suppressed 3T3-L1 adipogenesis more effectively than did the kernel extracts. These results suggest that CCT nut kernels (ME) and shells (WE) may be strategically used to enhance antioxidant or and anti-obesity materials.
