| Abstract: | The bitter melon seeds oil was extracted by Soxhlet extraction method,and the physicochemical characteristics of bitter melon seed oil were determined including iodine value,saponification number,unsaponifiable matter,melting point.The bitter melon seed oil was esterified in the way of potassium hydroxide-methanol esterification at room temperature,and the fatty acids composition of bitter melon seeds oil was detected by GC-MS.The results show that,both of oil content(36.81%) and protein contein(43.05%) of ... |
