알로에 베라 잎에서의 안트라퀴논 함량과 항산화능

Abstract

With the aims of obtaining the basic data for various product development using Aloe vera, the anthraquinones content and the antioxidant activity of Aloe vera leaves with different developmental stage and different leaf parts were determined and the effect of cutting direction and washing water temperature and dry period on anthraquinones content and antioxidant activity of Aloe vera leaves were evaluated in the study. Anthraquinones content of Aloe vera leaves was higher when the leaf was older, and as for the contents by leaf parts, the outer showed no difference, however in the whole leaf of mixture of inner and outer, the content decreased from top to base. Anthraquinones content did not show difference depending on washing water temperature, and longitudinal cutting showed less content than transversal cutting. There was also no difference in anthraquinones contents depending on dry period up to 7 days in room temperature. Antioxidant activity increased with the developmental stage, but did not show any difference depending on cutting direction, washing water temperature, and dry period.
