Summary
The genus Buddleja comprises around 100 species. Most of them are known from their traditional medicinal uses around the world. They are also widely spread due to their horticultural use as ornamental shrubs. The most popular species in the genus is Buddleja davidii Franch. – butterfly bush, and nowadays it is known in around 90 horticultural cultivars. Its aerial parts were used to estimate quantitatively and qualitatively active compounds such as phenolic compounds (phenolic acids, flavonoids, tannins) and iridoids. By means of pharmacopoeial and Folin-Ciocalteau method iridoid content in dry mass was 0.85%, flavonoid content was 0.47% (as hiperoside), phenolic acids content was 0.20%, tannins content was 10.21% and total phenolic compounds content was 3.36%. It was also established by HPTLC-densitometry and HPLC method that the main iridoid in aerial parts of butterfly bush is aucubin – iridoid glycoside, and the most abundant phenolic acid is chlorogenic acid, both obtained the most efficiently by means of heating extraction method.
