荆条[Vitex negundo L.var.heterophylla(Fra-nch)Rebd]属马鞭草科植物,药用其子和叶。经用荆条叶油的各种制剂对886例慢性气管炎患者治疗,获得较好疗效,其疗效与牡荆叶油相似,对慢性迁延期患者疗效较好,对喘息型患者疗效较差。挥发油是荆条治疗慢性气管炎的主要有效部分。自北京市郊密云县采集新鲜的荆条叶,经水蒸气蒸得其挥发油,收率约为0.15%。叶挥发油经气相色谱测定,含有16个以上成分。经分离鉴定,证明其中β-丁香烯和松香烯含量较高,分别占总挥发油的28.6%,26.2%。另外还含有α-蒎烯、柠檬烯、1,8-桉叶素、对-聚伞花素等成分。动物实验结果表明,叶挥发油具有显著的祛痰作
Vitex negundo L. var. heterophylla (Fra-nch) Rebd belongs to the family Verbenaceae, and its medicinal plants use its seeds and leaves. After treatment with 886 cases of chronic bronchitis, the treatment with various preparations of Vitex negundo leaf oil resulted in good curative effect. The curative effect is similar to that of vitex leaf oil. The curative effect is better for patients with chronic protracted phase and less effective for patients with asthmatic type. Volatile oil is the main effective part of Vitex in the treatment of chronic bronchitis. Fresh Vitex negundo leaves were collected from Miyun County in the suburbs of Beijing. The volatile oil was obtained by steam distillation and the yield was about 0.15%. The volatile oil from leaves contains more than 16 components as determined by gas chromatography. After isolation and identification, it was proved that the content of β-syringene and rosin was higher, accounting for 28.6% and 26.2% of the total volatile oil, respectively. It also contains components such as α-pinene, limonene, 1,8-cineole, and para-cymene. The results of animal experiments show that the volatile oil from leaves has a remarkable effect.
