Khat leaves, widely used as a stimulant in East Africa and the Arab Peninsula, contain the alkaloid, (-)-cathinone. The effects of this substance on the locomotor activity of rats were compared to those of (+)-amphetamine. Both substances were found to induce a similar degree of hypermotility. Furthermore, the effect of (-)-cathinone on the locomotor behaviour of hypophysectomized rats was analogous to that reported for (+)-amphetamine in such animals. The results support the claim that the symptoms caused by the chewing of khat are amphetamine-like.
巧茶树叶在东非和阿拉伯半岛被广泛用作兴奋剂,它含有生物碱(-)-去甲伪麻黄碱。将该物质对大鼠运动活性的影响与(+)-苯丙胺的影响进行了比较。发现这两种物质均可诱导相似程度的运动亢进。此外,(-)-去甲伪麻黄碱对垂体切除大鼠运动行为的影响与在这类动物中报道的(+)-苯丙胺的影响相似。这些结果支持了咀嚼巧茶所引起的症状类似于苯丙胺的说法。
