A fiber fraction (Aloe cellulose), the by-product obtained from Aloe vera gel processing was freeze dried and investigated for in vitro glucose/ bile acid retarding effects of powdered sample (100 mesh) comparing with commercial α-cellulose as a reference sample. We also examined the effectiveness of physiological functionality such as the antiobesity and anti-constipation on Sprague-Dawley (SD) rat. The Aloe cellulose powders during in vitro dialysis experiment for 2 hours exhibited the glucose and bile acid retarding index of 20.32-35.2% and 53.13-28.30%, respectively. Especially, freeze dried aloe cellulose showed the 2.5 and 1.2-6 times higher effect on in vitro glucose and bile acid retardation than those of α-cellulose. These relatively good retarding effects on glucose and bile acid diffusion suggest a potential of preventing from diabetes and arteriosclerosis of some extent. Also, the results from animal experiments on SD rats fed a high-fat diet for 4 weeks suggested that Aloe cellulose might be used as a novel dietary fiber showing an effective anti-obesity and anti-constipation effect.

국내에서 재배되고 있는 약용식물 및 농산물의 생리적 활성에 대하여 현재 연구가 활발하게 진행되고 있다. 본 연구에서는 추출조건별로 마늘의 유효성분 함량 및 항산화적 특성을 반응표면분석법으로 모니터링하여 최적 열수추출 조건을 설정하였다. 실험결과 총페놀성 화합물 함량, 전자공여능 및 아질산염 소거능은 용매비에 의해 많은 영향을 받고 있는 것으로 나타났다. Allin allicin 및 total thiosulfinate는 추출온도에 많은 영향을 받고
