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.
