Abstract Two new terpenoids (1 and 2), arenterpenoid D (1) and pinnasesquiterpene A (2), along with 16 phenylpropanoids (3–18) and 8 known terpenoids (19–26) were isolated from 70% EtOH extract of the Arenga pinnata (Wurmb) Merr. fruits. Their structures were elucidated by spectroscopic methods including HR-ESI-MS, 1D, and 2D NMR. The absolute configuration of arenterpenoid D (1) was defined by X-ray
摘要 从Arenga pinnata的 70% EtOH 提取物中分离出两种新的萜类化合物(1和2)、arenterpenoid D ( 1 ) 和 pinnasesquiterpene A ( 2 ),以及 16 种苯丙烷类化合物 ( 3 – 18 ) 和 8 种已知的萜类化合物 ( 19 – 26 ) (Wurmb)梅尔。水果。它们的结构通过包括 HR-ESI-MS、一维和二维核磁共振在内的光谱方法进行了阐明。arenterpenoid D ( 1 ) 的绝对构型由 X 射线晶体学分析确定。此外,我们评估了所有化合物的抗炎活性,结果显示2和21在脂多糖刺激的 RAW 264.7 细胞中暴露出对 NO 生成的中度抑制作用。
