Abstract

The article examines the representatives of the genus of Scutellaria L. distributed in the Ferghana Valley. On the basis of samples collected during field research and stored in the National Herbarium (TASH) Fund of the Institute of Botany Academy Sciences Republic of Uzbekistan, the growth of 23 species in the region was noted. Representatives of the genus Scutellaria L. are important due to the abundance of endemic species and their widespread use in modern pharmaceuticals. At the same time, opinions and comments on the study of natural resources of some species common in the valley are presented.

Highlights

The Fergana Valley is an intermountain lowland with an area of 22,000 km2 and 80,000 km2 of surrounding mountains
Our research field has shown that 23 species of Scutellaria L. are distributed in the flora of the Fergana valley in general, of which 15 species are distributed in the flora of Uzbekistan, and the remaining species are found in the flora of Kyrgyzstan and Tajikistan (Table 1)
The peculiarity of the study of the species distributed in the valley is that in recent years, there has been an increase in research on the chemical composition of many species in the region, the abstraction of species as a result of irregular collection of biologically active substances, the relative obsolescence of existing data, targeted floristic studies of flora in the region and is not confirmed by herbarium specimens of the species listed

Summary

Introduction

The Fergana Valley is an intermountain lowland with an area of 22,000 km and 80,000 km of surrounding mountains. The part of the Fergana Valley belonging to the Republic of Uzbekistan corresponds to the Kurama, Chatkal and Alai ridges, and administratively to Namangan, Fergana and Andijan regions (Figure 1). The species composition of the regions, the state of the population of plants belonging to a particular group, natural resources and others are being studied. (Lamiaceae) species in the flora of the Fergana Valley” Another need for research on Scutellaria L. species is that in recent years chemists working in our country have been conducting research to study the chemical composition of Scutellaria L. species in the flora of Uzbekistan. A.M. Karimov (2017) [2] and G.U. Siddikov (2018) [3] studied to isolate some species of Scutellaria L. distributed in the flora of Uzbekistan S. sordifrons Juz., S. phyllostachya Juz., S. comosa Juz., S. haematochlora Juz., S. immaculata Nevski ex Juz., S. ocellata Juz. and, for the first time, new flavonoids, glycosides, and aglycones. It is advisable to develop measures to preserve the natural populations of the species
