Comparison of chemical composition of the essential oil from Marrubium vulgare L. and M. incanum Desr. during the second year of cultivation

Abstract

Horehound herb (Marrubium vulgare L.) is harvested from plantations in Poland. In our country, there are also favorable conditions for M. incanum Desr. growing. The aim of the study was to compare the chemical composition of essential oils from M. vulgare L. and M. incanum Desr. in the second year of cultivation. The study revealed the presence of 31 compounds in the essential oil from M. vulgare L. and 24 compounds in the essential oil from M. incanum Desr. Chromatographic analysis revealed that the main compounds in the essential oil of M. vulgare L. from a two-year plantation were as follows: E-caryophyllene (34.51-36.78%), germacrene D (22.45-27.18%), bicyclogermacrene (9.54-11.12%), δ-amorphene (6.15-8.18%), and carvacrol (4.71-6.64%), whereas the following compounds prevailed in the oil from M. incanum Desr.: germacrene D (28.75-32.14%), E-caryophyllene (23.18-29.57%), α-cadinol (13.59-20.84%), and carvacrol (2.08-7.47%).

Phytochemical screening and antiviral activity of Marrubium vulgare

“…Terpene compounds isolated from the oils includes linalool, 1-8-cineole, thymol, marrubiin (Zawislak, 2012). In this study, the methanol crude extract of M. vulgare showed the highest level of inhibitory effect on HSV-1 followed by the hexane fraction.…”

Phytochemical profile and therapeutic potential of white horehound (Marrubium vulgare) – a review of the current state of knowledge

“…Ziele szanty zawiera ponadto do 0,09% olejku eterycznego [22][23][24]. Dominującymi związkami wchodzącymi w skład frakcji lotnej są seskwiterpeny, m. in.…”

Essential Oil of Two Iranian Horehound Species: Marrubium propinquum and Marrubium parviflorum

“…(28.75-32.14%). 52,56 Likewise, bicyclogermacrene, one of the major compounds of the sesquiterpene hydrocarbons in M. propinquum and M. parviflorum essential oils, was usually absent in the essential oil of M. vulgare, the most famous species of Marrubium genus. As we know, geographical, seasonal and climatic issues would commonly influence the chemical composition of the essential oils within various populations of these species.…”

“…40 Several studies on essential oil composition of Marrubium species are found in literature. [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] Evaluating the naturally occurring volatile constituents in the essential oil of a plant would be of value in characterizing species within a genus. According to the valuable results from previous studies on Marrubium species, M. propinquum and M. parviflorum were selected for assessing chemical components in their essential oils.…”
