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 i...
