Kyrgyzstan is one of the world centers of the origin of culture plants.In the country there is significantly noteworthy taxonomic variety – 4200 species of high plants and high degree of endemism Eremuruscristatus Phlomoidesfetisowii Pyrethrum sovetkinae Iridodictyumwinkleri Campanula eugenica Hedysarumchaitocarpum

Maintenance and accession of the seed bank of Kyrgyzstan’s wild flora: collection and processing of seeds • Collection is conducted in all regions of the republic. Expeditions are financed by the Royal Botanic Gardens, Kew – Millennium seed bank. • Storage in the seed bank is carried out at two low-temperature regimes at -20°C and in liquid nitrogen at -196°C. Seed processing is carried out according to the conventional techniques with consideration of the key elements of the genetic bank standards

Main flavones of Scutellaria plant roots • Why wogonin and its glucuronide wogonoside are so interesting? This group of flavones was not adequately investigated until 2007 since their content in native roots of S. baicalensis is inappreciably small compared to with the baicalein and baicalin content: wogonin concentration not exceeds 1% and plants themselves are under extinction. In 2007 it was found out that flavone wogonin selectively induces apoptosis only oncogenic cells, not affecting normally growing cells, meaning that it is possible to develop unique selectively acting cytotoxic drug on its base. At present the mechanism of wogonin selective action is studied, and a group of scientists in the German CancerResearch Center , Heidelberg, is actively working in this direction. There is a lack of natural source of wogonin production, and chemical synthesis of flavones did not show positive results for the present. In this situation the large-scale cultivation of isolated growing skullcap roots can be successfully used for wogonin production.
