ABSTRACT
<p><b>AIM</b>To study the chemical constituents of the pine needles of Pinus massoniana lamb..</p><p><b>METHODS</b>Various chromatographic techniques were used to separate and purify. Their physico-chemical properties and spectral data (UV, IR, MS, 1H-1 H COSY, HMQC, DEPT, HMBC and ORD ect.) were measured for structure elucication.</p><p><b>RESULTS</b>Three compounds were isolated from the n-BuOH fraction of water-extracts. Their structures were identified as massonianoside A (4), massonianoside A (7S, 8R)-3, 4, 9'-trihydroxyl-3-methyoxyl-7, 8-dihydrobenzofunan-1'-propanolneoligan-9-O-alpha-L-rhamnopyranoside, massonianoside C (5), (7S, 8R)-9,9'-dihydroxyl-3,3'-dimethyoxyl-7,8-dihydrobenzofunan-1'- propanolneoligan-4-O-alpha-L-rhamnopyranoside and cedrusin-4-O-beta-glucoside (6), (7S, 8R)-3',9,9'-trihydroxyl-3-methoxyl-7,8-dihydrobenzofunan-1'- propanolneoligan-4-O-beta-D-glucopyranoside.</p><p><b>CONCLUSION</b>Compound 4 and 5 are new compounds.</p>
