실험 목적
차에서 천연물인 카페인을 용해도 차이를 이용하여 추출하여 분리한다.
실험 원리
알칼로이드(alkaloids) - 질소를 함유하는 염기성 화합물로 식물계에 널리 분포한다. 단일 물질에 의해서 붙여진 명칭이 아니라 매우 광범위한 물질을 가리킨다.
카페인(caffeine) - 화학식 C8H10O2N4. 3개의
구조와 용리 시간과의 관계를 알아보고, 각 물질이 잘 흡수하는 파장대를 알아본다. 농도가 다른 카페인용액의 흡수 스펙트럼을 얻은 후 커피 한 잔에 포함된 카페인을 정량해본다.

Caffeine(C8H10O2N4)
caffeine)이라는 명칭을 붙였다. 19세기 말 헤르만 에밀 피셔(Hermann Emil Fischer)가 카페인의 화학구조를 밝혀냈다. 카페인의 화학식은 C8H10N4O2이다.
인간은 석기시대부터 카페인을 섭취하기 시작했으며, 초기에는 우연히 카페인을 함유한 식물의 씨앗, 나무껍질, 잎 등을 씹어 먹다가 피로를 가시게 하고 정
