摘　　要：采用索氏抽提法提取降香黄檀籽油,并对其理化性质及化学成分进行分析。结果表明:降香黄檀籽油酸值(KOH)、过氧化值、皂化值(KOH)、不皂化物、碘值(I)、折光指数(n2D0)、密度(20℃)、灰分分别为3.31 mg/g、5.07 meq/kg、196.78 mg/g、1.70%、108 g/100 g、1.459 6、0.915 g/cm3、0.025%;降香黄檀籽油在紫外光UV-B(290～320 nm)及UV-C(200～290 nm)波段有很强的吸收,可以用于防止紫外线损伤;降香黄檀籽油主要由亚油酸、油酸、棕榈酸组成,其含量分别为60.03%、17.48%及16.72%。此外,降香黄檀籽油中还含有丰富的生育酚、多酚及β-胡萝卜素,其含量分别为51.19、39.91、6.22 mg/100 g。因此,降香黄檀籽油有潜力成为一种新产品运用于食品、化妆品及医药工业。The Dalbergia odorifera T. Chen seed oil was extracted with Soxhlet method, and its physico- chemical properties, chemical composition were investigated. The acid value, peroxide value, saponification value, unsaponifiable matter, iodine value, refractive index, density and ash content of the oil were 3.31 mgKOH/g,5.07 meq/kg, 196.78 mgKOH/g, 1.70% , 108 gI/100 g, 1. 459 6,0. 915 g./cm3 and 0. 025%, respectively. The oil showed high absorbance in the UV- B （290- 320 nm） and UV- C （200- 290 nm） ranges which indicated that the oil could be used as a broad spectrum UV protectant. The major fatty acids in the oil were linoleie acid（60.03% ） ,oleic acid（ 17.48% ） and palmitic acid（ 16.72% ）. The contents of tocopherols, polyphenol and β - carotene were 51.19,39.91,6.22 mg/100 g, respective- ly. Dalbergia odorifera T. Chen seed oil could be used as a new product in food, cosmetic and pharmacy industry.
