Three new monoterpenes, olibanumols A (1), B (2), and C (3), and three new triterpenes, olibanumols H (4), I (5), and J (6), were isolated from olibanum, the exuded gum-resin from Boswellia carterii BIRDW. Their structures including the absolute configuration were determined by chemical and physicochemical evidence. Among the constituents, olibanumols A (1), H (4), and I (5), and isofouquierol (12)
从香蕉皮中分离出三个新的单萜寡酚A(1),B(2)和C(3)和三个新的三萜寡酚H(4),I(5)和J(6)。乳香(Boswellia Carterii BIRDW)的树胶树脂。它们的结构包括绝对构型由化学和物理化学证据确定。在这些成分中,低脂酚A(1),H(4)和I(5)和异茴香醚(12)在脂多糖激活的小鼠腹膜巨噬细胞中表现出一氧化氮的抑制活性。
