Chemical compositions of the seed of Korean green tea plant(Camellia sinecis L.)

녹차 종자의 일반성분

Relative content(% weight) of proteins, carbohydrates, lipids, and crude ashs in seed of korean green tea plant(Camellia simecis L.) are not different from those in seed of sunflower and safflower. However, the Camellia seed contains much higher crude saponin content(12.2%) than that of sesame(0.29%) or peanut(0.63%). It also contains 82% unsaturated fatty acids including oleic acid and contains tocopherol $(22\;{\mu}g/g,\;{\alpha}-form\;only)$ that is significantly less than of other oil-seed.

한국산 녹차 종자(Camellia sinecis L.)에 함유된 단백질, 탄수화물, 조지방, 조회분 함량은 해바라기(Helianthus annuus)씨나 잇꽃종실(Carthamus tinctorius L.) 등과 대등하였으나, 조사포닌은 12.2%로 참깨(0.29%)나 땅콩(0.63%)보다 월등히 높게 함유하였고, oleic acid를 비롯한 불포화 지방산 조성은 82%였다. Tocopherol은 ${\alpha}-form$만 $22\;{\mu}g/g$ 보였을 뿐 일반종자보다 현저히 낮은 수준으로 함유하였다.
