The genus Lontcera (Caprifoliaceae) comprises of 200 species with 21 growmg m Kazakhstan. The genus Grludes shrubs with both climbing and non-climbing sprouts. The fiuits of most species are either inedible or poisonous

The present aimed to investigate Fwo Lonïcera species, Lonïcera tltensïs Pojark and L. altaica Pall. ex DC collected in different vegetation stages for chemical composition of the essential oils. These species belong to subsection of blue honeysuckles Caeruleae Rehd (section Istka Rehd.), both of them have edible fiuits (2—4).

Flower, leaf at blooming and fruiting stages and fimits of two Lonïcera species were hydrodistilled with Clevenger apparatus to obtain essential oils. Chemical compositions of the oils were investigated by GC-FID and GC,'MS techniques. Detected constituents were classified as monoterpenes, sesquitelpenes, alkanes, phenylpropanoids, fatty acids, aldehydes and alcohols.

Quantitative and qualitative diversity depending on species, organ and phase of development of the plants have been detected A high abundance of alkanes (17.1—44.5%) was detected in the volatiles of all the L. ïltensïs organs Investigated. In the flowers, leaves at blooming stage and fruits of L. altaïca alkanes were found as dominating group. However, alkanes have not been detected in the leaf oil of L altaïca collected at fruiting stage Polycy:lic aromatic hydrocarbons were the distinguishing characteristic in the volatiles of L. altaïca leaves at fruiting stage while oxygenated monoterpenes were in high percentages in the leaves at blooming stage. The flowers of L ïhensïs and L_ altaïca have been found to be rich by oxygenated sesquitelpenes (21.0 and 15.0%, respectively) with hexahydrofamesyl acetone as the major representative.

The present work is the first contribution into chemistry of volatiles of Lonïcera species growing in Kazakhstan.
