Essential oil of the malagasy grass Elionurus tristis Hack. contains several undescribed sesquiterpenoids

Chemical Constituents of the Mushroom Dictyophora indusiata and Their Anti-Inflammatory Activities

“…Edible fungi are considered prolific producers of structurally diverse terpenoid compounds, as these fungi possess an extensive repertoire of natural product biosynthesis pathways [ 44 , 45 ]. Compound 1 was a tricyclic sesquiterpenoid with a skeleton of antsorane [ 46 , 47 ], compound 2 was a rearranged cuparane-type sesquiterpenoid [ 48 ], and compound 4 was an acyclic norsesquiterpenoid [ 49 , 50 ]. The antsorane skeleton contained in compound 1 was quite unusual.…”

“…Several analogs were successively identified from Eremophila fraseri [ 51 ], Vetiveria nigritana [ 52 ], and Chrysopogon zizanioides [ 53 ]. The structure of antsorane was fully characterized by Gabriel P. Garcia et al in 2019 [ 47 ]. To the best of our knowledge, compound 1 is the second natural compound ever reported with this specific sesquiterpenic ketone skeleton and the first one isolated from fungi.…”

Chemical constituents and biological activities of essential oil from Mentha longifolia: effects of different extraction methods

“…After four hours, the EOs were collected and dried by sodium sulfate anhydrous and then stored at 4°C until analysis. [10] The extraction was performed three times.…”

Comprehensive Two-Dimensional Gas Chromatography Advances in Technology and Applications: Biennial Update

“…The authors determined odor-active compounds by GC−O, identifying 13 substances in this study, from which bulnesol (rosylike odor) was the main odorant. The same group used GC×GC to study the composition of other fragrance ingredients, such as vetiveryl acetate 135 and the essential oil of aerial parts and roots of Elionurus tristis, 137 identifying key components and determining odorants.…”
