摘要
A method for quantitative determination of the sum of flavonoids in the new herbal preparation profem (herbal tea and polyextract) has been developed with a view to standardization of the initial raw materials. Profem is based on the herbs of Panzerina lanata (L.) Sojak (Lamiaceae), shoots of Pentaphylloides fruticosa (L.) O. Schwarz (Rosaceae), and roots of Comarum palustre L. (Rosaceae).
