碩士 === 國立臺灣大學 === 化學研究所 === 88 === The air dried and peices of wood of the Pinus massoniana Lamb were extracted with acetone for three times. The combined acetone extract was purified by chromatography on silica gel, thin liquid chromatography（TLC）and high performance liquid chromatography（HPLC）.Twenty-nine compounds have been isolated from the acetone extract. Those include monoterpenoids、sesquiterpenoids、diterpenoids and stilbenes. Twenty-nine compounds include one monoterpenoids：massonolide（M1）；one sesquiterpenoids：α-cedrol（S1）；twenty-three diterpenoids：methyl 12β-hydroxy-7,13-abietadien-18-oate（D1）、methyl 12-oxo-7,13-abietadien-18-oate（D2）、Pinunolidone（D3）、methyl 9,10α-epoxy-9,10-seco-8,11,13-abietatrien-18-oate（D4）、methyl 14-hydroxy-7-oxo-8,11,13-abietatrien-18-oate（D5）、methyl 17-nor-15-oxo -8,11,13-abietatrien-18-oate（D6）、methyl 12-methoxy-8,11,13-abietatrien-18-oate（D7）、methyl 12-hydroxy-8,11,13-abietatrien-18-oate（D8）、massolide A（D9）、massolide B（D10）、8,11,13-abietatrien-18-oic acid（D11）、methyl 8,11,13-abietatrien-18-oate（D12）、18-nor-8,11,13-abietatrien-4α-ol（D13）、methyl 7-oxo-8,11,13-abietatrien-18-oate（D14）、5,6-dehydro-7-oxo-8,11,13-abietatrien-6,18-olide（D15）、methyl 15-hydroxy-8,11,13-abietatrien-18-oate（D16）、18-norpimara-8(14),15-dien-4α-ol（D17）、18-norisopimara-7,15-dien-4α-ol（D18）、pimarol（D19）、isopimarol（D20）、methyl 7-oxopimara-8(14),15-dien-18-oate（D21）、methyl 7-oxoisopimara-8,15-dien-18-oate（D22）、8(14),15-isopimaradien-18-oic acid（D23）；two sterols：β-sitostenone（Ste1）、β-sitosetrol（Ste2）；and stilbenes：(E)-3-hydroxy-5-methoxystilbene（Sti1）、(E)-3,5-dimethoxystilbene（Sti2）. Among these compound，（D1）、（D2）、（D7）were first isolated from natural sources,and（M1）、（D3）、（D4）、（D5）、（D6）、（D9）and（D10）are new compounds.
