園藝作物天然色素之研究2.鬰金色素之抽取和不同品種間含量之分析
Studies on the Natural Coloring Matters of Horticultural Crops Ⅱ. Extraction and Variability of Curcumin Content in Different Curcuma Varieties.
摘要
鬰金爲植物性天然黃色色素原料之一種，本省原有大黃、二黃等品種之栽培，産量雖高，但品質較差，乃就印度、印尼、泰國等引進品種試從比較分析其色素含量，並探討其抽取方法。

Curcuma longa rhizomes contained a golden yellow odoriferous essential oil and an orange-yellow pigment. The purpose of this experiment is to extract and determine the content of curcumin yellow in tumeric which were introduced from India, Indonesia and Thailand respectively. Curcumin was extracted respectively with ether, acetone and bezene, and was determinated quantitatively by ultraviolet spectra in comparison with authentic samples. The contents of curcumin in tumeric were dependent on varieties, cultural environment and farm management. The variety from Indonesia contained a higher curcumin than that of India and Thailand.
