Extraction and Idenfication of Phenolic Compounds in Acetone Extract from Guava Leaf

Qian He

Abstract

In this paper,the condition of extracting polyphenolic compounds by different solvents was discussed.The optimum extracting condition was determined as: 50% acetone solution,extraction temperature 60℃,extraction time 1h,40 Mu and the total phenols recovery was 14.54%.In addition,3 new compounds(gallic acid,chlorogenic acid kaempferol) and 5 known compounds(procatechuic acid,ferulic acid,caffeic acid,quercetin and rutin) were identified in the guava leaf extract by RP-HPLC analysis.
