Chemical components in the hexane-extract mixture from Phalaenopsis leaves were isolated and identified during the spike induction process. Several lipophilic components in the hexane-extract mixture were isolated and identified as oleic acid, 1,2-O-dilinolenoyl-MGDG, 1-O-linolenoyl-2-O-linoleoyl-MGDG, and α-tocopherol by HPLC and NMR techniques. It is noteworthy that only one isomer of α-tocopherol was isolated from Phalaenopsis leaves based on NMR spectra analysis. MGDG have a great potential to be a control factor in the regulation of spike process of Phalaenopsis. It is the first time to identify the chemical MGDG related to temperature-controlled process of Phalaenopsis. These components have hydrophilic and hydrophobic moieties in the same molecule to act as potential amphiphiles. The use of the entire mixed hexane extract to form liposomes containing the dmbpyPtCl₂ complex greatly enhanced the reactivity of the complex for inhibiting E. coli growth compared with the use of a single amphiphile.

蝴蝶兰叶片中单半乳糖二酰基甘油的糖脂在生长和穗诱导期形成混合脂质体，增强对大肠杆菌生长的抑制作用

在穗诱导过程中，分离并鉴定了蝴蝶兰叶的己烷提取物混合物中的化学成分。己烷提取物混合物中的几种亲脂性成分被分离出来，并通过 HPLC 和 NMR 技术鉴定为油酸、1,2-O-二亚油酰基-MGDG、1-O-亚麻酰基-2-O-亚油酰基-MGDG 和 α-生育酚。值得注意的是，根据核磁共振谱分析，仅从蝴蝶兰叶子中分离出了一种α-生育酚异构体。MGDG 有很大潜力成为蝴蝶兰穗过程调控的控制因子。首次鉴定出与蝴蝶兰控温过程相关的化学物质MGDG。这些组分在同一分子中具有亲水性和疏水性部分，作为潜在的两亲物。与使用单一两亲物相比，使用整个混合己烷提取物形成含有dmbpyPtCl ₂复合物的脂质体大大增强了复合物抑制大肠杆菌生长的反应性。
