[Technology for tablets with herbal extracts and evaluation of its quality].

The article deals with the development of technology for production of tablets containing dry herbal extracts. Dry herbal extracts of two different compositions were produced by spray drying using BUCHI 190 apparatus. The quality of dry extracts was evaluated by determination the loss of extract mass during the drying process, and estimation of the amount of biologically active combinations. The tableting methods for dry herbal extracts--direct compression and also employing granulation--were used. The quality of the produced tablets was determined by examining their appearance, resistance to abrasion, crushing strength, mass uniformity, disintegration time. Contents of biologically active compounds in tablets were evaluated by the quantitative methods.
