The volatile constituents of Calamintha sylvatica Bromf. subsp. sylvatica

Abstract

The volatile constituents of Calamintha sylvatica Bromf. subs. sylvatica in the different development stages (pre-blossom, full blossom and post-blossom) have been analysed using GC and GC-MS. Thirty-three constituents were identified. The most representative compound in all stages was cis-piperitone oxide (66.6-74.6%).

Essential Oils of TwoCalamintha glandulosa(Req.) Bentham chemotypes in a Wild Population from Zakynthos, Greece

“…In M. x piperita the main constituents were menthofuran (21.5%) and pulegone (13.9%) in the inflorescence oil and menthone (24.2%) and menthol (45.8%) in the leaf oil, while in M. spicata, the main constituents were piperitenone oxide (32.4-46.3%) in the inflorescence oils and 1,8-cineole (11.9-40.5%), trans-piperitone oxide (1.4-33.5%) and piperitenone oxide (19.7-26.2%) in the leaf oils (39). C. sylvatica plants prior to flowering (vegetative stage) had a higher isomenthone content (13.4%) than flowering (1.9%) or post-flowering plants (0.9%) (22).…”

Composition and antimicrobial activity of the essential oil of Clinopodium ascendens (Jordan) Sampaio from Madeira

“…subsp. sylvatica 23,24 of southern European species, show major differences: the first concludes that pulegone is the major product (54.2%), whereas the second states that the major product is cis-piperitone oxide (66.6%, 69.2% and 74.6%, depending on the stage of plant evolution, pre-full blossom and post-blossom).…”

Plant Volatiles Providing Additional Evidences to the Occurence of a Wild‐Growing Population of Calamintha vardarensis (Greuter et Burdet) Šilić Outside of Its Natural Habitat

“…Since the oils from the plant material collected prior to, during, and after anthesis show differences, it was important to include these literature data in the MVA data set (C. sylvatica ssp. sylvatica oils [9]). …”
