地檀香、滇白珠、高山地檀香系杜鹃花科(Ericaceae)白珠属(Gaultheria L.)植物。广泛分布于我国西南和中南各省。据我所调查,云南约有18种和6个变种。地檀香(G.forrestii Diels),滇白珠[G.yunnanensis(Franch.)Rehd.],高山地檀香(G.griffithianaWight)在云南分布甚广,藏量很大。该三种植物的化学研究尚未见有报导。同属多种植物的叶精油,经前人研究确定,其主要成分为水杨酸甲酯(methyl salicylate),含量达96—99％。这种精油的商品名通称为冬绿油(wintergreen oils),广泛用于医药与香料工业。上述三种植物的新鲜枝叶,以水蒸气蒸馏所得精油,呈淡黄色至赤红色,出油率0.5—
Sandalwood, Chinese white pearl, and highland sandalwood are plants of the genus Gaultheria L. of the family Ericaceae. Widely distributed in China’s southwest and south-central provinces. According to my survey, there are about 18 species and 6 varieties in Yunnan. G.forrestii Diels, G. yunnanensis (Franch.) Rehd., and G.griffithiana Wight are widely distributed in Yunnan and have a large amount of reserves. Chemical studies of the three plants have not yet been reported. The leaf essential oils belonging to various plants are determined by previous studies and their main component is methyl salicylate with a content of 96-99%. The trade name of this essential oil is commonly known as wintergreen oils and is widely used in the pharmaceutical and perfumery industries. The fresh leaves of the three plants mentioned above were distilled from steam to obtain a light yellow to reddish color with an oil yield of 0.5 -
