摘　　要：油茶是我国主要的食用木本油料树种,其种子制备的茶油是优质食用植物油,其副产物油茶饼粕中亦含有丰富的生物活性物质。油茶饼粕经冷冻干燥除水后,通过索氏提取法获得苯/乙醇提取物,于450℃的He气流中进行热裂解,然后对热裂解产物进行Py-GC/MS联机分析,采用色谱峰面积归一化法计算各组分的相对含量,并鉴定出30种化合物。分析结果表明,油茶饼粕苯/乙醇提取物的450℃热裂解产物中,含有丰富的名贵生物医药、名贵香料、特色化工原料等成分,不仅可用于高档化妆品和护肤品,还可用于食品、染料与工业溶剂等优质原料。研究结果为油茶饼粕这一丰富资源的深加工利用提供了新的方向。Camellia oleifera cake was firstly lyophilized and extracted by Soxhlet extraction method, the benzene/ethanol extractive was treated with a thermal cracking process in He-flow at 450℃, and then the thermal-cracking product was analyzed by on-line Py-GC/MS, the relative contents of each component were computed by adopting chromatographic peak area normalization method, a total of 30 compounds were identified. The analyse results show that the pyrolyzate of the benzene/ethanol extractives contains various kinds of precious biomedical, spicery ingredients and specific chemicals, which are of great potentialities for high-grade cosmetics and skin care products, as well as excellent materials for food, dye and solvent industries. The findings provide new developing directions for deep processing and utilization of Camellia oleifera cakes resources.
