The oil yields of caperberry seeds vary from 29.20% (C. spinosa var. herbaceae) to 35.02% (C. spinosa var. inermis). The proportion of linoleic acid in the seed oil of C. ovata var. palastina was higher (43.8%) than that in the seed oil of other capers. Oleic acid contents of caper seed oil varied between 18.5% (C. spinosa var. herbaceae) and 20.9% (C. spinosa var. aegyptia). The major tocopherol was γ‑tocopherol in all the varieties of caper seed oil, which was higher in C. spinosa var. inermis (161.3 mg/100 g) than in C. spinosa var. herbaceae (85.8 mg/Kg) (p < 0.05). The major sterol was beta-stosterin in all the varieties of caperberry seed oils, and were found between 3241.4 mg/kg (C. spinosa var. inermis) and 5298.1 mg/kg (C. spinosa var. herbaceae), but there was significant difference (p < 0.05). The contents of stigmasterin in seed oil changed between 675.7 mg/kg (C. spinosa var. inermis) and 749.0 mg/kg (C. spinosa var. herbacea).

caperberry种子的油的产率从29.20％（变化C.刺变种herbaceae）至35.02％（C.刺变种无芒雀麦）。亚油酸在种子油中的比例C.卵形变种。与其他刺山柑的籽油相比，palastina的含量高（43.8％）。跳跃种子油的油酸含量为18.5％（之间变化C.刺v AR。herbaceae）和20.9％（C.刺变种aegyptia）。在所有刺山柑种子油中，主要的生育酚为γ-生育酚，在刺槐中的含量更高。无定形（161.3 mg / 100 g）比C. spinosa var。草本植物（85.8 mg / Kg）（p  <0.05）。主要固醇是β-内stosterin在所有品种caperberry种子油的，并且发现3241.4毫克/公斤（之间C.刺变种无芒雀麦）和5298.1毫克/公斤（C.刺变种herbaceae），但有显著差异（p  <0.05）。stigmasterin的在种子油675.7毫克/公斤之间变化的内容（C.刺变种无芒雀麦）和749.0毫克/公斤（C.刺变种herbacea）。
