    COMPOZIȚIA CHIMICĂ A ULEIULUI VOLATIL DE NARCIS (NARCISSUS POETICUS L.) LOCAL
    (CEP USM, 2024) Ciocârlan, Alexandru; Arîcu, Aculina; Lungu, Lidia; Blaja, Svetlana; Dragalin, Ion; Popescu, Violeta
    Species of the Narcissus genus are important sources of biologically active compounds frequently used in various fields. Concrete, absolute, extracts and essential oil obtained from Narcissus poeticus L. plants, due to their specific chemical composition, are unique ingredients for the perfumery industry in the development of luxury products and medicine. The chemical composition of the concrete obtained from local narcissus plants has been described previously. In this paper, the data regarding the extraction of absolute from concrete and its chemical composition are reported. As result of the GC-MS analysis, 16 constituents belonging to various classes of natural compounds were identified.

    POLICHIMISMUL INTRASPECIFIC MENTHA SPICATA
    (CEP USM, 2020) Peleah, Elena; Melnic, Victor; Dragalin, Ion
    Pentru studiul comparativ al diferitelor chemotipuri de Mentha spicataL. acestea au fost colectate atât din populaţii spontane de pe teritoriul Moldovei, cât şi din alte zone geografice. Pentru depistarea posibilităţilor potenţiale ale ecotipuri-l or de mentă a fost efectuat studiul particularităţilor vegetaţiei, ponderea de ulei, compoziţia calitativă auleiului. După compoziţia calitativă mentele studiate au fost împărţite în 3 grupe.

    SYNTHESIS OF NEW HOMODRIMANE SESQUITERPENOIDS CONTAINING DIAZINE, 1,2,4-TRIAZOLE AND CARBAZOLE RINGS
    (2018) Duca, Gheorghe; Aricu, Aculina; Lungu, Lungu; Tenu, Nadejda; Ciocarlan, Alexandru; Gutu, Yacob; Dragalin, Ion; Barba, Alic
    The present paper reports on six step synthesis of 11-homodrim-6,8-dien-12-oic acid N-substituted amides containing diazine, 1,2,4-triazole and carbazole rings based on commercially available sclareolide. The mentioned compounds were prepared for the first time by interaction of the generated in situ acyl chloride with some heterocyclic amines: 2- and 4-aminopyrimidine, 2-aminopyrazine, 5-amino-1,2,4-triazole and N-aminocarbazole. Their structures were fully elucidated by elemental and spectral analyses (IR, 1H and 13C NMR).
