Vapor fraction from seeds of Glycine max (L.)Merr. and composition thereof

A vapor fraction from seeds of Glycine max (L.) Merr., which vapor fraction is prepared by the process comprising the steps of:

• (a) providing a crude extract of the seeds in an alcohol solution containing alcohol at the concentration lower than about 15% wt. or in water;
• and
• (b) vaporizing the crude extract at a barometric pressure lower than about 1 atm and at a temperature lower than about 110° C. to obtain the vapor fraction;
• wherein a spectrogram of the 50 mL of the vapor fraction taken at 200 nm through a high performance liquid chromatography (HPLC) using Waters Sphersorb™-ODS2 column with an inner diameter (I.D.) of 4.6 mm, a length (L) of 250mm and a particle size of 5 mm comprises peaks at a retention time of 2.910, 5.190, 13.190, and 50.815 minutes with the coefficient of variation of 8%, where mobile phase is at 0 to 5 minutes is 95% H2O/5% CH3CN;
• at 5 to 30 minutes is 95% H2O/5% CH3CN in gradient, at 30 to 80 minutes is 75% H2O/25% CH3CN in gradient;
• at 80 to 100 minutes is 0% H2O/100% CH3CN in gradient;
• at 100 to 101 minutes is 0% H2O/100% CH3CN in gradient;
• and at 101 minute is 95% H2O/5% CH3CN and a flow rate is 1 mL/min.
