STUDY OF THE ACCUMULATION DYNAMICS AND LOCALIZATION OF 9,13-EPOXYLABDANES IN THE VEGE-TATIVE ORGANS OF INTRODUCED PLANTS OF THE GENUS LAGOCHILUS
Extracts of the plant Lagochilus inebrians Bunge (Lamiaceae) are used as sedatives, antihypertensive and anti-allergic agents, and to stop bleeding. The main active ingredients of this plant are diterpenoids of the 9-13-epoxylabdanes series, as well as some alkalides. Not rational use of stocks of wild Lagohilus has led to the fact that this plant is currently included in the Red Book. Currently, work is underway to introduce this plant species. Therefore, the study of the dynamics of accumulation and localization of 9,13-epoxylabdans in the vegetative organs of introduced and wild plants of the genus Lagochilus (Lamiaceae) is of interest in terms of collecting the plant for use as a medicinal raw material, for the systematics of data on the accumulation of diterpenoids in the vegetative organs of the plant, for their use. in practical terms, the preparation of diterepenoids and their modification is an urgent task. Some systematic chemical studies of plants of the genus Lagochilus (Lamiaceae) were carried out by the school of Academician A.S. Sadykov. As a result of studying 10 plants of the species Lagochilus (Lamiaceae), more than 20 new diterpenoids of the labdan series were isolated. All of them are natural derivatives of the diterpene alcohol lagochilin. Their structure and configuration were established using IR, PMR and mass spectroscopy, as well as by synthesis from lagochilin or transformation into lagochilin. By studying the composition of diterpenoids of an introduced and wild plant of the genus Lagochilus, it was shown that the main diterpenoids of the 9-13-epoxylabdans series, exhibiting the main biological activity: lagochiline and its acetyl derivatives, accumulate mainly in the leaves and calyx of the plant in August, which is also consistent with some literature data. data. For isolation, extraction methods were used with various solvents. The methods of thin layer chromatography and spectroscopic research methods such as IR, PMR and mass spectrometry were used for identification.
