Rhynchosia nulubilis has been used as supplements of estrogen for preventing postmenopausal osteoporosis and as food in oriental medicine. Contents of free amino acid of germinated R. nulubilis seeds treated by low molecular weight soluble chitosan(LMSC) were investigated. R. nulubilis seeds were germinated to 2 mm-length root at 20℃ after presoaking in 0.05% LMSC(1, 3, 5, 10 kDa) solution for 4hr. Total free amino acid content of 5 kDa chitosan-treated group was higher than those of control and the other group, also total essential amino acid content in all chitosan-treated group was higher than those of control. Arginine(Arg), tyrosine(Tyr), valine(Val), methionine(Met), tryptophan(Trp) contents in treated group were higher than those of control. Especially, 5 kDa chitosan of various molecular weight of chitosan was highest content which showed in Arg(331 mg%), Tyr(19 mg%), Val(36 mg%), Met(34 mg%), Trp(53 mg%). In the Met content, chitosan-treated group was four time than control(8 mg%), 33~34 mg% in chitosan-treated group.
