Major components include glycosides and saccharide such as aloin, isdobsrbaloin, 7-hydroxyaloin and 5-hydroxyaloin. Major functions are heat clearing, bowel relaxing, sterilization and antiphlogosis. Yuanjiang, Yunnan Province is a tropical greenhouse and typical dry-hot valley with an annual rainfall below the surface evaporation, which is suitable for aloe planting.
It is a trend to perform extraction, separation and purification of active aloe ingredients. Single or multiple active ingredients will be applied in pharmaceuticals and nutraceuticals after extraction and separation with efficient functions, leading to higher economic benefits.

Certain market demand for acemannan with high purity exits for functions of antitumor and immunity enhancing. The development trend of the biological engineering and pharmaceutical industries is to extract and separate functional components from plants.
