Litchi pericarp discs, (1 g), from 10 fruits were rinsed and incubated in 60 ml of distilled water for 4 h, and then the initial electrolyte leakage was monitored with a conductivity meter (DDS-11A, China). Each sample was continually rinsed for 2 h after being boiled for 5 min, and the final electrolyte leakage (total electrolyte) was again monitored. Relative leakage rate was defined as percent of initial electrolyte. Enzyme assay Litchi pericarp (2 g) from 10 fruits was homogenized with 25 ml of 50 mM sodium phosphate buffer (pH 7.0) containing 0.25 g of polyvinylpyrrolidone (PPVP,Sigma). After centrifugation at 18,000g for 20 min, the supernatant was used as enzyme extract. POD (EC1.11.1.7) activity was based on the determination of guaiacol oxidation at 470 nm by H2O2. The change in absorbance at 470 nm was followed every 30 s by spectrophotometer(GBC Centra-10, Australia) (Lacan &Baccou, 1999). POD activity was defined as DA470/min/g FW (Li, 2000). Total SOD (SOD, EC 1.15.1.1)activity was assayed according to the method of Oberley and Spitz (1985), based on the ability of SOD to inhibit the reduction of nitroblue tetrazolium (NBT, Sigma). The absorbance was monitored at 550 nm. One unit of SOD is the amount of extract that gives 50% inhibition of the reduction rate of NBT. Malondialdehyde (MDA) determination MDA determination was followed the method described by Li (2000). Litchi pericarp, (1 g), from 10 fruits was homogenized in 15 ml of 10%TCA. The homogenate was centrifuged at 10,000g for 20 min, and then 2 ml supernatant of sample was reacted with 2 ml of 0.6% 2-thiobarbituric acid. The absorbance was monitored at 600, 532 and 450 nm, respectively. Calculation of MDA was based on the following formula: C(μm/l) = 6.45(A532 － A600) －0.56 A450.
