  摘要：

  使用高效液相色谱和电喷雾电离-四极杆飞行时间串联质谱联用的分析方法，从番薯叶中分​​离并鉴定了十六种新型半乳糖脂和十种已知的半乳糖脂。使用这种技术，确定了脂肪酰基的结构和区域化学以及酰基链上双键的位置。通过分析一维和二维核磁共振谱来鉴定糖部分。通过气相色谱-质谱法确定了多不饱和脂肪酸双键的位置，并在某些情况下确定了它们的几何形状。这是甘薯叶中半乳糖脂的首次报道。

  Synthesis of digalactosyl diacylglycerols and their structure–inhibitory activity on human lanosterol synthase

  摘要：

  Digalactosyl and monogalactocyl diacylglycerols (DGDG and MGDG), which were identified as anti-hyperlipemia active components in Colocasia esculenta (Taro), were synthesized. The inhibitory activity of DGDG, MGDG and related compounds on human lanosterol synthase was evaluated as anti-hyperlipemic activity. DGDG with two myristoyl groups at both sn-1 and sn-2 positions and with an oleoyl group at the sn-1 position showed the most potent activity. (C) 2004 Elsevier Ltd. All rights reserved.

  Sixteen novel and ten known galactolipids have been isolated and characterized from the leaves of Ipomoea batatas L. (sweet potato) using an analytical method based on high-performance liquid chromatography coupled with electrospray ionization-quadrupole time-of-flight tandem mass spectrometry. Using this technique, the structures and regiochemistries of the fatty acyl groups and the positions of the
