Abstract:
Objective: To study the chemical constituents from the fresh pineneedles of Pinus massoniana. Methods: Certain chromatography means were used in the isolation and purification, and the structures of all the compounds were identified by means of spectroscopic analysis and physicochemical properties. Results: Fourteen compounds were elucidated respectively as (+)-catechin (1), (+)-gallcatechin (2), phlorin (3), tachioside (4), 3,4-dimethoxyphenyl-1-O-β-D-glucopyranoside (5), 3,4-dimethoxyphenyl-1- O-(3-O-methyl-α-L-rhamnopyranosyl)-1→2-β-D-glucopyranoside (6), citrusin D (7), (6S,7E,9R)-roseoside (8), raspberry ketone- O-β-D-glucopyranoside (9), (-)-oplopan-4-one-10-α-O-β-D-glucose (10), massonianoside D (11), massonianoside B (12), isolariciresinol-9'-O-α-L-arabinofuranoside (13), and (2R,3R)-taxifolin-3'-O-β-D-glucopyranoside (14). Conclusion: Compounds 2-6, and 10 are isolated from the plants of Pinus L. for the first time, and compounds 7-9 are obtained from P. massoniana for the first time.
