科普專欄–薯不揀單 - 三十秒科學–貓草

貓隻遇到貓草後，不但會舔草，亦會用頭及臉與草磨擦，甚至會以全身的方式在草上滾動。529Please respect copyright.ＰＥＮＡＮＡmhjHPiMjcW

過程通常歷時5-15分鐘，然後就會有以小時計的冷靜期。529Please respect copyright.ＰＥＮＡＮＡECcJC5ajtA

（圖2）有日本科學家從貓草中提煉出一種科學物質Nepetalactol。529Please respect copyright.ＰＥＮＡＮＡtCHn650vhm

在18隻本身對貓草有正面反應的貓隻中，有15隻主動走向含Nepetalactol的紙張上，利用身體跟其磨擦，歷時接近10分鐘。529Please respect copyright.ＰＥＮＡＮＡLS3pZLxj9H

（圖3）有圖有真相，實驗室的貓，流浪貓，就連豹及美洲獅都屈服在貓草的Nepetalactol化學物質上。529Please respect copyright.ＰＥＮＡＮＡpA4V6ZzRKR

然而，狗隻及老鼠則對這化學質並無興趣。529Please respect copyright.ＰＥＮＡＮＡcGokCoCr0t

（圖4）經過一系列的實驗後，證實貓隻吸入貓草的Nepetalactol化學物質後，血液的β-endorphin份量會隨之上升，導致愉悅感增加。529Please respect copyright.ＰＥＮＡＮＡMg4l2YWCXq

同時，貓草的Nepetalactol化學物質塗在身上後，亦具備驅蚊效果。529Please respect copyright.ＰＥＮＡＮＡDUxFB1tGab
529Please respect copyright.ＰＥＮＡＮＡTPPrMIfCti
有科學家更利用是次研究的結果，申請了專利利用Nepetalactol製作驅蚊劑，同時亦正在進行研究貓草會否含有物質可對抗其他害蟲。529Please respect copyright.ＰＥＮＡＮＡyq3BJc43oN
