Study of Sedative Tea Phytocomplex within the Framework of Studies Aimed at Creation of a Rectal Dosage Form with Antihistaminic Effect

Resumo

We designed a new complex drug with antiallergic effect containing, in addition to the main component loratadine, a phytocomplex for an extra therapeutic effect. A collection of plants with sedative activity is chosen and the optimal agent for extraction of bioactive compounds (40% ethanol) and optimal degree of plant fragmentation are determined. Chemical composition of the sedative tea is evaluated by reverse phase HPLC. The marker components of the species are detected: xanthohumol and isoxanthohumol — Humulus lupulus cone components, Mentha piperita rosmarinic acid, and scutellareine, Menyanthes trifolia element — quercetin-3-rutinoside, and caffeic acid. Standardization of the species by the absolute graduation method in conversion to quercetin-3-rutinoside is suggested.
