单叶蔓荆(Vitex rotundifolia)的果实可治头痛。曾报道用硫氰化铁法测定出其果实的甲醇提取物显示较强的抗氧化活性,优于合成抗氧化剂BHA(3-特丁基-4-羟基茴香醚);并分离出环烯醚萜类、苯丙素、黄酮、木脂体和二萜苷,其中有许多化合物的抗氧化活性均优于BHA。继续报道从其果实中分离出8种新的半日花烷型二烯(1～8)和2种已知松香烷型二萜(9、10)。 干燥单叶蔓荆果实粉末(2914g)用甲醇提取,提取物在己烷和甲醇中分配,溶于甲醇的部分用脱脂棉过滤,滤液减压浓缩,残余物经Diaion HP-20柱、硅胶柱、ODS柱及HPLC纯化,得到8种新成分1～
The fruit of Vitex rotundifolia can cure headaches. It has been reported that the methanol extract of the fruit determined by the method of iron thiocyanate shows stronger antioxidant activity than the synthetic antioxidant BHA (3-tert-butyl-4-hydroxyanisole); and the iridoid is isolated. Anthraquinones, phenylpropanoids, flavonoids, lignans, and diterpene glycosides, many of which have higher antioxidant activity than BHA. It continues to report the isolation of eight new hemicolane-type dienes (1 to 8) and two known terpene diterpenes (9, 10) from their fruits. The dried single-leaf vitex fruit powder (2914g) was extracted with methanol, the extract was partitioned between hexane and methanol, the methanol-soluble fraction was filtered with absorbent cotton, and the filtrate was concentrated under reduced pressure. The residue was passed through a Diaion HP-20 column, silica gel column, ODS column and HPLC purification to obtain 8 new components 1 ~
