Study on biomolecules in extractives of Camellia oleifera fruit shell by GC–MS

Abstract

This study aims to present an integrated process that can be used to produce biomedical and biological active components from the fruit shell of Abel. Through the Foss method, Aldehyde, acid compounds, acyl and alcohol compounds account for 22.7, 15.93, 0.24 and 61.13% of the extractives which were extracted from fruit shell by methanol solvents. Furfural, Pyrazole-4-carboxaldehyde, 1-methyl- and 5-Hydroxymethylfurfural account for 4.74, 1.22 and 58.78% of the extractives which were extracted from the fruit shell of Abel by ethanol solvents. Aldehyde, acid and amine compounds account for 5.01, 56.18 and 7.20% of the extractives which were extracted from the fruit shell of Abel by ethyl acetate solvents. The extractives of fresh flesh of bayberry were rich in rare drug, biomedical and biological activities.

“…According to the analysis of the graph, the main structure of these lignin is very similar to the characteristic band of the functional group, and all the spectra show a typical lignin mode. The lignin characteristic absorption peaks did not change significantly at 1658 cm -1 , 1456 cm -1 , 1413 cm -1 , 1380 cm -1 , 1329 cm -1 , 1277 cm -1 , 1089 cm -1 , 1049 cm -1 and 881 cm -1 [28]. It is mainly OH stretch at the peak 3358 cm -1 , -CH stretch at the peak 2974 cm -1 , C=C stretch at 1658 cm -1 , C-H stretch at the peak 1456 cm -1 , and C-C stretching vibration at 1277 cm -1 , 1049 cm -1 is C-O stretching.…”
