Preparation and Controlled-Release Analysis of Ethyl Cellulose – Moxa Leaf Powder Solution Microcapsules

Abstract:

Article Preview

In this paper, moxa leaf powder solution microcapsules are firstly prepared by phase separation of ethyl cellulose. The microcapsule granules prepared are spherical; with good dispersibility and diameters of 10-100μm; have good effects in preservation and prolonged-releasing of active compositions in moxa leaf. The controlled-release experiment proves that after immersing in normal saline for 24 hours under constant temperature of 37°C, releasing amount of the microcapsules is less than 80%, thus the active compositions in moxa leaf still exist in the granules.
