The palm oil industry generates several byproducts, and more than half of the dry weight of the waste is of oil palm leaf whereby the tissue is underutilized. Recently, several research studies found promising potential of oil palm fronds as a source of nutraceutical due to its bioactive properties. However, the chemical composition of the tissue is still not deciphered. Using reversed-phase liquid chromatography (LC) electrospray mass spectrometry (ESI-MS), glycosylated apigenin and luteolin were separated and identified from oil palm (Elaeis guineensis Jacq.) leaf and structures of the constituents were elucidated by collision-induced dissociation (CID) tandem MS. From 28 derivatives of the flavones, 9 compounds were conjugated with hydroxymethylglutaric (HMG) acid. Improved knowledge on oil palm especially on bioactive component of the leaf tissue will allow correlation of its beneficial effects and further promotes efficient utilization of this agriculture byproduct.
棕榈油产业会产生多种副产品，其中超过一半的干物质重量来自油棕的叶子，而这些叶子的组织并没有得到充分利用。最近，多项研究发现，油棕的叶子具有作为营养保健品的潜在前景，这是因为它具有生物活性。然而，其组织的化学成分仍未被破解。利用反相液相色谱（LC）电喷雾质谱（ESI-MS），从油棕（Elaeis guineensis Jacq.）叶中分离并鉴定出糖基化芹菜素和木樨草素，通过碰撞诱导解离（CID）串联质谱阐明了成分的结构。从 28 种类黄酮的衍生物中，有 9 种与羟甲基戊二酸（HMG）酸结合。对油棕的了解，特别是对其叶组织的生物活性成分的了解，将有助于关联其有益效果，并进一步促进对这种农业副产品的有效利用。
