简介：

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 prolongedreleasing
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℃, releasing amount of
the microcapsules is less than 80%, thus the active compositions in moxa leaf still exist in the
granules.
