| 系统性地分析了野茉莉属主要油料树种的种子含油率、油脂脂肪酸组成及燃料特性。研究测定了野茉莉属8个油料树种种子的形态指标、含油率、油脂脂肪酸组成及理化性质，并预估其脂肪酸甲酯理化性质。结果表明：野茉莉属8个油料树种种子含油率为22.24%~54.86%，其油脂脂肪酸碳链长度主要介于C14~C20，主要组分为油酸和亚油酸；油脂碘值（I）为114.16~124.34 g/100 g，皂化值(KOH)为159.89~168.98 mg/g；脂肪酸甲酯运动黏度为3.55~3.60 mm2/s，十六烷值为48.87~50.73，密度为862.88~864.58 kg/m3，高热值为40.67~41.10 kJ/g，冷滤点为-670~-1.54?℃；通过主成分分析将8个树种分为3大类。通过综合分析，野茉莉属8个油料树种均可作为非粮柴油植物的初步筛选树种。 |

| The oil content in seed, fatty acid composition and fuel properties of oils from the main biodiesel plants species of Styrax spp. were systematically analyzed. The morphological indexes, oil content in seed of eight biodiesel plants species and physicochemical property, fatty acid composition of the oils were measured, and the physicochemical property of fatty acid methyl ester was estimated. The results showed that the oil content in seed of eight species ranged from 22.24% to 54.86%, the length of fatty acid carbon chain was mainly in C14-C20, and the key components were oleic acid and linoleic acid. The iodine value of the oils ranged from 114.16 gI/100 g to 124.34 gI/100 g, and the saponification value ranged from 159.89 mgKOH/g to 168.98 mgKOH/g. The kinematic viscosity, cetane number, density, high heating value and cold filter plugging point were 3.55-3.60 mm2/s, 48.87-50.73, 862.88- 864.58 kg/m3, 40.67-41.10 kJ/g and -6.70--1.54?℃, respectively. Eight biodiesel plants species could be clustered into three groups according to the principal component analysis. By comprehensive analysis, eight biodiesel plants species of Styrax spp.could be all used as preliminary screening plant for non-grain diesel plants. |
