초록

The proximate composition and the levels of anthraquinone, phenolics and polysaccharide content from three domestic aloe species(aloe vera, Aloe arborescens and aloe verascens) according to different portions(whole leaf, peel and gel) were analyzed and compared. The proximate compositions were varied among the species and portions of aloes, especially according to aloe portions. Moisture content of 3 aloe species according to portions were 91.87∼99.37% indicating that moisture level reached the most of proximate composition. Mineral analysis showed that aloe portions contained seven mineral components and the predominant mineral components were Ca, K, Mg and Na. Mineral contents of peel portion was about several ten and hundred times higher than those of gel showing significantly higher level of mineral content in peel portion. Total amino acids were in the ranges of 15∼17 kinds, and their contents in gel portion was 10 folds higher than that of peel portion showing the different profiles compared to mineral and proximate compositions. Total phenolics content was found to be the highest in peel followed by whole leaf and gel. Total phenolics content in peel was the highest in Aloe verascens(370.21mg/100g) followed by arborescens(290.54mg/100g) and vera(287.94mg/100g). These levels in gel portion was in the range of 5 and 7% of peel level only. Anthraquinone content in gel portion of three Aloe species was in the range of 0.004 ∼0.001%, and was remarkably lower than that of peel(0.031∼0.061%). The highest polysaccharide content of 708mg/L exhibited in gel of Aloe arborescens followed by peel, whole, and gel of Aloe vera. Thus, these findings support the possibility of whole leaf or total processes which use whole leaf and peel portion respectively for enhancing the required level of effective component.
