[Study on Chemical Constituents of Stalk from Pottsia laxifora]
Objective:
To study the chemical constituents of stalk form Pottsia laxifora.
Methods:
The chemical constituents were isolated by various chromatography methods,and the structures were elucidated by spectroscopic methods,physical and chemical properties.
Results:
Twelve compounds were isolated and their structures were identified as β-sitosterol( 1),salicylic acid( 2),resorcinol( 3),4-hydroxybenzoic acid( 4),protocatechuic acid( 5),vanillic acid( 6),syringic acid( 7),scopoletin( 8),cleomiscosin D( 9),( +)-lyoniresinol( 10),(-)-loliolide( 11) and daucosterol( 12).
Conclusion:
Compounds 1 ~ 11 are isolated from this plant for the first time.
