Comparison of the Composition of Three Mahonia Plants Based on GC-MS Analysis

Abstract

Plant material evidence inspection is Mahonia bealei (Fort.) Carr., Mahonia fortunei (Lindl.) and Mahonia bodinieri Gagnep. are three common medicinal plants commonly found in Mahonia. In this study, gas chromatography-mass spectrometry (GC-MS) was used to compare the chemical constituents of stems and leaves of these three plants. The results showed that 6 of the volatile oils of the three plant species contained the same chemical composition, which was neophytadiene, palmitic acid, n-dodecane, octacosane, erucamide, and vitamin E oil, but the percentage content was difference. The main components of the volatile oils of the three plant stems were different. Erucamide was only detected in Mahonia fortunei (Lindl.) Fedde, oleic acid amide only detected in Mahonia bealei (Fort.) Carr. , and oxidized cyclooctene , and four compounds such as triphenylphosphine oxide was detected in Mahonia bodinieri Gagnep. ..
