Glucosinolates and Fatty Acid, Sterol, and Tocopherol Composition of Seed Oils fromCapparis spinosaVar.spinosaandCapparis ovataDesf. Var.canescens(Coss.) Heywood

As a unique woody oil tree, Camellia oleifera Abel originates from southern China and is now being cultivated in central China, such as the southern Henan province. The aim of this work is to determine some physiochemical parameters, fatty acid profile and tocopherol composition of the Camellia oleifera seed oils harvested in southern Henan in the 2016 season. The lipid contents of the kernel are in the range of 28.39- 56.94% on dry matter. The acid value (AV), saponification value (SV), iodine value (IV), and refractive index of the oils are in the ranges: 0.22-5.17 mg KOH/g, 178.90-196.91 mg KOH/g, 82.0-87.1 g I2/100g, and 1.4667-1.4720 (nD25) , respectively. The main fatty acids are: palmitic 7.07-9.52%, palmitoleic 0.09-0.22%, stearic 1.45-2.94%, oleic 77.02-84.33%, linoleic 5.19-11.23%, linolenic 0.53-0.70% and arachidic 0.22-0.70%. The sn-2 fatty acid composition is: 84.36-91.33% oleic, 7.14-14.22% linoleic, and 0.89-1.96% others. The tocopherol content is in the range of 39.55-75.94 mg/100g oil, including mainly α-tocopherol (33.98-67.82 mg/100g) and γ-tocopherol (5.57- 8.27 mg/100g) when the oils are extracted with hexane; and 14.91-44.36 mg/100g, including mainly α-tocopherol (9.42-37.08 mg/100g) and γ-tocopherol (5.50-7.33 mg/100g) when the oils are extracted by ethyl ether. The physiochemical properties C. oleifera seed oils from southern Henan are similar to those from other districts of China.

Major Acid

Seed oils were hydrolyzed under mild conditions and the major conjugated fatty acid of each oil was isolated and identified. In two families, species which were closely related botanically contained different but isomeric acids. Thus, in the Bignoniaceae, Jacaranda chelonia had cis trans,cis-8,10,12-octadecatrienoic acid as a major acid while Catalpa speciosa had trans,trans,cis-9,11,13-octadecatrienoic acid. In the Cucurbitaceae, Momordica charantia had the ordinary cis,trans,trans-9,11,13-octadecatrienoic (α-eleostearic) acid while M. balsamina had cis,trans,cis-9,11,13-octadecatrienoic (punicic) acid. M. balsamina is a new and convenient source of punicic acid. α-Eleostearic acid was identified as a major acid in examples of Valerianaceae and Rosaceae. Further proof was obtained that the fatty acid of Calendula officinalis (Compositae) is trans,trans,cis-8,10,12-octadecatrienoic acid.
