I. INTRODUCTION
I. 簡介

In this experiment you will be working with oils prepared from caraway seeds
and spearmint leaves. Each oil has a distinct and characteristic odor, yet carvone is the
ponent in both oils! It is amazing that the difference in odor is attributable
solely to a difference in chirality of the carvone in the two oils. Due to chirality of odor
receptors in the nose the R-carvone and S-carvone fit into different receptor sites, hence
3
different odor. Can you distinguish between the odors? 8-10% of the population cannot.

在這個實驗2中,你將從葛縷子種子和綠薄荷葉中提煉出油來。兩種油各自有
種與眾不同的氣味,然而香芹酮是這兩種油中的主要成分! 令人吃驚的是氣味的不
同完全是由於兩種油中香芹酮手性的不同而引起的。由於鼻子中氣味感受體的手
