SESQUITERPENE LACTONS FROM AERIAL PARTS OF ARTEMISIA CAMPESTRIS (var. MARSCHALLIANA) SPRENG.

About 500 species of wormwood are known in the world. In flora Azerbaijan, this genus is represented by 42 taxa. The main chemicals shown to be sesquiterpene lactones, coumarins, steroids, and essential oils. From aerial parts Artemisia campestris (var. Marschalliana) Spreng., collected during phenological phase budding, an acetone extract was obtained, which, after removal solvent, subjected column chromatography neutral alumina oxide (II degree activity) eluted graduality with hexane, benzene, chloroform their mixtures increasing polarity. As a result chromatographic separation, two lactones eudesmann type were isolated - α-santonin (substance I) m.p. 170–172 °С artemisin II) 201–203 °С. Moreover, acetyl derivative III) 196–198°C, identification which carried out on basis physicochemical spectral data (UV, IR, 1H, 13C, 13C Dept 45, 90, 135 NMR spectra obtained. Substances I II from Spreng. for first time.
