알로에 다당체를 포함하는 투명한 육질의 특징은 무엇인가? | 1,2) 알로에 다당체는 보통 알로에 잎의 녹색 외피(outer green rind)를 제거한 다음, 내부의 투명한 육질(clear pulp)로부터 분리된다. 투명한 육질은 parenchyma cell 또는 mesophyll cell이라고 불리는 투명한 세포로 구성되어 있는데, 그 크기는 아주 커서 큰 것은 1000 μm 정도가 되는 것으로 알려져 있다.3) 이들 세포는 세포벽(cell wall), 퇴화된 세포 내 소기관(degenerated cellular organelles) 및 점성이 있는 세포 내용물로 구성되어 있으며, 육질에서 각 부분이 차지하는 비율은 건조 중량을 기준으로 세포벽이 16.2%, 퇴화된 세포내 기관이 0.7%, 점성의 세포 내용물이 83.1% 정도 되는 것으로 보고되어 있다.3) | |
Acetylated glucomannan는 무엇인가? | 1,4,5) 알로에 젤로부터 다양한 종류의 다당체가 분리되었 는데, 대표적인 것이 acetylated glucomannan이다. Acetylated glucomannan은 일종의 저장 다당체(storage polysaccharide) 로서 parenchyma cell의 세포질 안에 들어 있다. 세포벽에도 mannose를 함유한 다당체, cellulose 및 pectic polysaccharide 등이 존재한다. | |
알로에 베라에서 추출한 다당체의 생리활성에는 어떤 것들이 있는가? | 알로에 베라에서 추출된 다당체는 면역증강, 항염증, 상처치유, 항미생물, 항당뇨, 항암, 항산화 및 조혈촉진 효능등 다양한 생리활성을 나타내는 것으로 보고되어 있다.1,2) 알로에 다당체는 보통 알로에 잎의 녹색 외피(outer green rind)를 제거한 다음, 내부의 투명한 육질(clear pulp)로부터 분리된다. |
