文摘内容
The constituents of oil from Broussonetia papyrifera (L.) Vent. fruits were analyzed qualitatively and quantitatively by means of GC-MS-COMPUTER DATABASE system. 27 compounds from the oil were identified. Among them, linoleic acid, methyl palmitate,oleic acid and linoleic acid ester were major constituents, which relative contents were 63.982% , 20.914%, 4. 263% and 3. 505% respectively. And the absolute content of linoleic acid was determined (51.26% ) by GC external standard method. Analyzed key physical constants related to its quality standard, the results indicated that relative density, refraction and pH were 0. 911 7 - 0. 914 0, 1.473 1 - 1. 473 5 and 5. 50 - 5. 78 respectively。
