The composition of the kernel oils of two Calophyllum species (Calophyllum calaba L. and Calophyllum inophyllum L.) was investigated. The physico-chemical properties and fatty acid composition of the kernel oils were examined. In two species, oleic acid C18:1 (39.1-50%) is the dominating fatty acid followed by linoleic acid C18:2 (21.7-31.1%) as the second major fatty acid. Stearic C18:0 (13.4-14.3%) and palmitic C16:0 (11-13.7%) acids are the major saturates. The oils contains an appreciable amount of unsaturated fatty acids (70.8-73.10%). Most of the fatty acids are present as triacylglycerol (76.7-84%), twenty one triacylglycerols are detected with predominantly unsaturated triacylglycerols. The total unsaponifiable content, its general composition and the identity of the components of the sterol and tocopherol fractions are presented. In both species, analysis of the unsaponifiable fractions revealed the preponderance of phytosterols, mainly stigmasterol (35.8-45.1%) and beta-sitosterol (41.1-43.1%). Among the eight tocopherols and tocotrienols present in two species, variations exist; alpha-tocopherol (183 mg/kg) is the main tocopherol in Calophyllum calaba L. and Delta-tocotrienol (236 mg/kg) is the dominant tocotrienol in Calophyllum inophyllum L.
对两种红厚壳属植物（红厚壳Calophyllum calaba L.和海棠果红厚壳Calophyllum inophyllum L.）种仁油的成分进行了研究。检测了种仁油的理化性质和脂肪酸组成。在这两个物种中，油酸C18:1（39.1 - 50%）是主要脂肪酸，其次是亚油酸C18:2（21.7 - 31.1%）作为第二主要脂肪酸。硬脂酸C18:0（13.4 - 14.3%）和棕榈酸C16:0（11 - 13.7%）是主要的饱和脂肪酸。这些油含有相当数量的不饱和脂肪酸（70.8 - 73.10%）。大多数脂肪酸以三酰甘油形式存在（76.7 - 84%），检测到21种三酰甘油，主要是不饱和三酰甘油。给出了总不皂化物含量、其一般组成以及甾醇和生育酚馏分成分的鉴定结果。在这两个物种中，对不皂化物馏分的分析表明植物甾醇占优势，主要是豆甾醇（35.8 - 45.1%）和β - 谷甾醇（41.1 - 43.1%）。在这两个物种中存在的8种生育酚和生育三烯酚中存在差异；α - 生育酚（183毫克/千克）是红厚壳Calophyllum calaba L.中的主要生育酚，而δ - 生育三烯酚（236毫克/千克）是海棠果红厚壳Calophyllum inophyllum L.中的主要生育三烯酚。
