Comparative Analysis of the Composition of Flower Volatiles from Lamium L. Species and Lamiastrum galeobdolon Heist. ex Fabr.
TLDR
The volatiles of fresh flowers from nine natural populations of four Lamium species and Lamiastrum galeobdolon were analyzed by GC/MS and the presence of homological series of straight chain alkanes from C12 to C31 was shown. Expand
Iridoid Patterns of Genus Plantago L. and Their Systematic Significance
TLDR
The distribution of 14 iridoid glucosides in 14 Plantago L. species (44 samples corresponding to 18 taxa) was shown and showed a good correlation with morphological and other chemical features of the representatives of genus Plantago. Expand
A biosystematic study ofValeriana officinalis (Valerianaceae) distributed in Bulgaria
TLDR
Valeriana officinalis L. is an extremely polymorphic polyploid complex and the two subspecies were subdivided into diploid and tetraploid cytotypes. Expand
Benzoxazinoids and iridoid glucosides from four Lamium species.
TLDR
A new class of compounds for the plant family Lamiaceae, benzoxazinoids, was found in Lamium galeobdolon and the iridoids, 5-deoxylamiol and sesamoside, as well as the phytoecdysone, 24-epi-pterosterone, were found for the first time for the genus Lamium. Expand
Iridoid glucosides from Plantago cornuti, Plantago major and Veronica cymbalaria
TLDR
The iridoid alpinoside with a 8,9-double bond was found for the first time in genus Veronica, and the main constituents in V. cymbalaria were the known catalpol, amphicoside and verproside. Expand
Constituents of essential oils from Nepeta cataria L., N. grandiflora M.B. and N. nuda L
TLDR
Essential oils from Bulgarian populations of Nepeta nuda L. and N. cataria L. (two origins) and of the Caucasian endemic N. grandiflora M.B. (Lamiaceae) were analyzed and some of the constituents were found for the first time in the genus Nepeta from natural sources. Expand
Iridoid Glueosides from Plantago altissima L., Plantago lanceolata L., Plantago atrata Hoppe and Plantago argentea Chaix.
TLDR
Globularin and methyl ester of the desacetylasperulosidic acid were isolated for the first time from Plantaginaceae plants (P. altissima and P. lanceolata) and asperuloside was found for thefirst time in P. atrata. Expand
Iridoid Glueosides from Plantago altissima L., Plantago lanceolata L., Plantago atrata Hoppe and Plantago argentea Chaix.
Plantago altissima L., Plantago lanceolata L., Plantago atrata Hoppe and Plantago argentea Chaix. were examined for iridoids. In all four species aucubin and catalpol were found. Globularin andExpand
