PMAS (English full name: pure material acemannan source), is a new material first proposed by the research team of Jufeel Natural Drug R&D Center led by Professor Zhang Rongxuan, a part-time professor School of Pharmacy and Life Sciences of Changzhou University.

　　PMAS is extracted from freeze-dried aloe powder to a scale of one of two hundred, 1 kilo of aloe leaves can only extract 5 grams of freeze-dried aloe powder; 5 grams of freeze-dried aloe powder can only extract 2.5 grams of aloe polysaccharides; 2.5 grams of aloe polysaccharides can only extract 1 gram of acemannan; 1 gram of acemannan can only extract 0.7 gram of PMAS that is the most valuable substance to the human body among known aloe ingredients.

　　Jufeel's PMAS has undergone several updating and upgrading of stock oral solution, concentrated oral solution, super concentrated oral liquid, freeze-dried powder for injection, orally disintegrating tablets, sublingual instant film and so on, and its content is also continuously increased during each upgrading. At the same level of preparation, in consideration of convenience of taking, bioavailability (absorption effect), absorption rate, safety and so on, its peroral dosage form has been always favored by Jufeel's users.

　　When users are taking PMAS oral solution, what they are concerned about most is the absorption rate.

　　Jufeel's PMAS sublingual instant film is the most advanced oral mucosal feeding system and the peroral dosage form independently developed by Jufeel's North R & D Center based on the "oral disintegration technology". The film can be rapidly absorbed through the sublingual capillaries by being placed under the tongue of the mouth without water.
