Antimicrobial activity and chemical composition of the essential oils of mosses (Hylocomium splendens (Hedw.) Schimp. and Leucodon sciuroides (Hedw.) Schwägr.) growing in Turkey
(TÜBİTAK, 2013)In the present work, the volatiles of mosses [Hylocomium splendens (Hedw.) Schimp. (Hylocomiaceae) and Leucodon sciuroides (Hedw.) Schwägr. (Leucodontaceae)] have been investigated by GC-FID and GC/MS. Fifty-eight compounds ... -
Antimicrobial activity and volatile constituents of the flower, leaf, and stem of Paeonia daurica grown in Turkey
(TÜBİTAK, 2011)The volatile constituents of the essential oils from the flower, leaf, and stem of Paeonia daurica Andrews were analyzed by GC and GC-MS. A total of 74 compounds were identified, constituting over 95.0%, 80.8%, and 98.2% ... -

(TÜBİTAK, 2010)The essential oils of mosses [Tortula muralis Hedw. (Pottiaceae), Homalothecium lutescens (Hedw.) H. Rob. (Brachytheciaceae), Hypnum cupressiforme Hedw. (Hypnaceae), and Pohlia nutans (Hedw.) Lindb. (Mniaceae)] were ... -
Design and synthesis of new 1,2,4-triazole deriaties containing morpholine moiety as antimicrobial agents
(TÜBİTAK, 2012)2-Morpholine-4ylethyl-3H -1,2,4-triazole-3-ones (2a, 2b) were obtained from the condensation between the corresponding ethoxycarbonylhydrazones and 2-morpholinoethanamine. 2a was conerted to acetohydrazide (4) ia the ... -
