摘 要： 對云南德宏高含量3-蒈烯思茅松資源調(diào)查表明，其林分松脂的3-蒈烯含量為8.52 %～20.11 %,平均含量為19.50%；單株3-蒈烯含量最大值為25.33 %, 高于高山松10.33 %；產(chǎn)品松節(jié)油中3-蒈烯含量達(dá)11 %以上； 德宏的梁河與潞西林分的3-蒈烯含量平均值分別為8.52 %、20.11 %，3-蒈烯在松節(jié)油中的含量的平均值分別為19.47 %和34.88 %；以單株為對象，3-蒈烯最大含量和3-蒈烯在松節(jié)油中的含量的最大值分別是27.50%和44.99 %。而其他地區(qū)思茅松松脂中3-蒈烯含量則較低，云南松松脂的3-蒈烯含量也相對較低。對這一已成規(guī)模的高含量3-蒈烯資源，建議重視開發(fā)利用。

Abstract: Study on the chemical characteristics of oleoresins from Pinus kesiya var. langbianensis in Dehong of Yunnan was carried out by gas chromatography and mass spectrometry.Contents of 3­carene in oleoresin are as high as 8.52 %-20.11%,averaging 19.50%. The content of 3­carene in oleoresin from one pine is as high as 25.33 %,or 10.33 % higher than that from P.densata oleoresin;The contents of 3­carene in turpentine  are over 11 %; The contents of 3­carene in oleoresin from Luxi and Lianghe of Yunnan  are 8.52 % and 20.11 % respectively and 3­carene contents in turpentine are 19.47 % and 34.88 % respectively.The maximum 3­carene contents in oleoresin and turpentine are 27.50% and 44.99 % respectively from one tree. However, 3­carene contents are low in oleoresins of P. kesiya var. langbianensis and P. yunnanensis Franch.The resource of oleoresin from P. kesiya var.langbianensis has been exploited on a large scale.Attentions should be paid to the exploitation of P. kesiya var.langbianensis.
