Study on the volatile oil of leaf of red gland Lonicera in guangxi

Objective:To compare volatile oil of Lonicera confusa(red gland Lonicera) fresh leaves with dry leaves and provide evidence for further study of Lonicera confusa leaves.Methods:GC-MS was used to identify chemical composition in volatile oil in red gland Lonicera leaves.Results:93 chemical components were separated in fresh leaves in which 39 chemical components were identified;88 chemical components were separated in dry leaves in which 51 chemical components were identified. The main components of fresh leaves of red gland Lonicera were n-Hexadecanoic acid(11.90%),Phytol(11.79) and 9,12,15-Octadecatrienoic acid,methyl ester,(Z,Z,Z)(7.08);The main components of dry leaves of red gland Lonicera were 1,6-Octadien-3-ol,3,7-dimethyl-(27.62%),Phytol(7.57%) and 2,6,10,14,18,22-Tetracosahexaene,2,6,10,15,19,23-hexamethyl-,(all-E)(4.70%).Conclusion: There are significant differences between volatile oil between fresh and dry leaves.
