The HPLC spectra of the phenolic components from the N. lappaceum L. peel (Fig. 8) illustrated the presence of ellagic acid (tR = 14.08 min), corilagin (tR = 9.41 min) and geraniin (tR = 8.75 min). The content and accumulation of individual phenolic compounds in rambutan peels of Rongrien and Seechompoo cultivars are illustrated in Figs. 9 and 10, respectively
