Biological analysis on extractives of bayberry fresh flesh by GC–MS

Abstract Bayberry has been largely planted in China, and the waste of fresh flesh of bayberry was still abandoned. Therefore, the extractives of fresh flesh of bayberry were studied to further utilize the bio-resources. Through the Foss method, the result shown that ketone, aldehyde, ester and acid compounds were accounted for 1.30, 92.61, 0.54 and 6.09% of the extractives which were extracted from fresh flesh of bayberry by methanol solvents. Aldehyde, bicyclic sesquiterpenes, acid, ester and alcohol compounds accounted for 53.74, 9.95, 28.49, 6.79 and 1.05% of the extractives which were extracted from fresh flesh of bayberry by ethanol solvents. Ketone, aldehyde, carbohydrate, acid and ester compounds accounted for 4.77, 77.95, 12.06, 4.77 and 0.44% of the extractives which were extracted from fresh flesh of bayberry by ethyl acetate solvents. The extractives of fresh flesh of bayberry were rich in rare drug and biomedical activities and the ethanol is more better to extract the fresh flesh of bayberry.
