Large amount of soybean sprout will be collected and processed in the first quarter of the project period to obtain sufficient amount of material. In the meantime, identification of the chemical classes including bioactive compounds will also be conducted. The large-scale chemical fractionation will be performed and the compounds in each fraction will be determined in the second quarter. Candidate molecules will be further selected, and the authentic compounds will be obtained in the third quarter. Their anti-inflammatory activity will be tested in the third and fourth quarters.
