Dacryodes rostrata (kembayau) is an important food and oil resource for local communities in Borneo, but it is not commonly known to wider community. The objective of this work is to valorize kembayau fruit by evaluating the characteristics of the oil from the fruit. In this study, the physicochemical characteristics and the lipophilic essential nutrient; the fatty acid composition, vitamin E and beta-carotene content of oils obtained from the peel, pulp and seeds of kembayau fruits were studied. The pulp of the kembayau fruit contained highest proportion of oil, followed by peel and seed. Kembayau fruit contained vitamin E and had trace amount of beta-carotene. Besides, kembayau fruit oils were not toxic to BRL3A cells, provided hepatoprotection and reversed lipid peroxidation in paracetamol-induced toxicity. Our results suggest that kembayau can be a potential source for cooking oil as the physicochemical characteristics are comparable with commercial source such as oil palm.
长喙龙脑香（kembayau）是婆罗洲当地社区重要的食物和油脂来源，但更广为人知的社区对其并不了解。这项工作的目的是通过评估该果实油的特性来提升kembayau果实的价值。在本研究中，对从kembayau果实的果皮、果肉和种子中获得的油的物理化学特性以及亲脂性必需营养素；脂肪酸组成、维生素E和β-胡萝卜素含量进行了研究。kembayau果实的果肉含油比例最高，其次是果皮和种子。kembayau果实含有维生素E且β-胡萝卜素含量微量。此外，kembayau果实油对BRL3A细胞无毒，具有肝脏保护作用，并能逆转对乙酰氨基酚诱导毒性中的脂质过氧化。我们的结果表明，kembayau作为食用油的潜在来源，其物理化学特性与油棕等商业来源相当。
