RESULTS AND DISCUSSION
Carotenoids and Tocopherol Contents
A representation of the carotenoids and tocopherols profiles of geuk fruit were shown in Fig. 2 and Fig. 3. Under the HPLC conditions adopted, carotenoids and tocopherols were well separated and the peak eluted in the following order; lycopene, α-carotene and β-carotene at 450 nm and α-tocopherol at 290 nm. Two different parts of geuk fruits were analyzed, and the quantitative results are shown in Table 1. The major carotenoids were lycopene and β-carotene. Seed aril contained the highest concentration of lycopene was 846.84 μg/g. α-Carotene and β-carotene concentrations were 30.93 μg/g and 29.43 μg/g, respectively. Among tocopherols, α-tocopherol was only detected, with the mean concentration of 252.15 μg/g. Pulp also was found to contain the highest amount of lycopene (390.15 μg/g) and contained relative amounts β-carotene (211.32 μg/g) and α-Carotene (71.58 μg/g). α-Tocopherol value of pulp was 204.60 μg/g.
