Abstract
본 발명의 구성은
레스베라트롤 용액을 100% 에탄올에 녹인 후 나노캡슐의 기본 피복물질로 수용성 키토산(chitosan)과 폴리글루탐산(poly--glutamic acid, PGA)을 이용하여 키토산/PGA 나노입자를 제조한 것으로, 상세 제조공정은 하기와 같다.
1. 레스베라트롤 용액은 100% 에탄올에 녹여 제조.
2. 레스베라트롤 함유 키토산/PGA 나노캡슐을 제조하기 위하여 키토산 용액에 레스베라트롤 용액을 충분히 분산시킨 후 계속 교반(1,000 rpm).
3. 동시에 PGA 용액을 peristaltic pump를 이용하여 키토산과 레스베라트롤
혼합용액에 일정 속도(1.0 mL/min)로 떨어뜨려 레스베라트롤 함유 나노캡슐을 제조.
이때, 레스베라트롤 함유 키토산/PGA 나노캡슐의 크기가 100-150 nm 이다.
