Secondary Metabolites from Pinus mugoTurra subsp. mugo Growing in the Majella National Park (Central Apennines, Italy)

Abstract

In this study, we examined the composition regarding secondary metabolites of P. mugo Turra ssp. mugo growing in the protected area of Majella National Park, which is the southernmost station of the habitat of this species. Both the nonpolar and polar fractions were considered. In particular, the essential-oil composition showed a high variety of compounds, and 109 compounds were detected, and 101 were identified, among which abietane-type compounds have a taxonomic relevance. Abietanes were also isolated from the polar fraction, together with an acylated flavonol and a remarkably high amount of shikimic acid.

Volatiles as Chemosystematic Markers for Distinguishing Closely Related Species within the Pinus mugo Complex

“…Them ajor components were a-pinene (2) 1 ), d-car-3-ene (6), and bornyl acetate(18)comprisingtogether in average39.3, 40.1,and 48.1% of the volatile composition for P. uncinata, P. uliginosa,a nd P. mugo,r espectively (Table). On the other hand, the present resultsd iffer from the recently reported essential-oil composition of P. mugo [19] [21].Differences in the composition and in the contents of particular volatile Due to the difficulties in obtaining agreateramount of plantmaterial from P. uliginosa, which is one of the most threatened species in Poland, it was decided to use HS-SPME as aless invasive method to obtain the volatiles of this protected tree species. The highest variation between individual samplesw as foundi nt he amounts of the three main volatile constituents, viz., d-car-3-ene (0.02 -24.38%), a-pinene(10.56-30.68%), and bornyl acetate( 1.36 -11.54%).…”

Comparison of Chemical Composition of the Essential Oils from Different Botanical Organs of Pinus mugo Growing in Poland

“…Several papers described P. mugo essential oil, its chemical composition and biological activities: antimicrobial, antioxidative, anti‐inflammatory, cytotoxic, and insect larvicidal . Most of them concerned the oils from P. mugo growing wild in the mountains of Southern Europe, i. e. Austrian Alps, Julian Alps, Dinaric Alps and Apennines . In the oils studied previously, 30–70 components were usually identified.…”

Chemical Composition and Interpopulation Variability of Essential Oils of Taxus baccata L. from Serbia

“…A considerable number of compounds (52 in total) were found in amounts between 0.1 and 0.5%. Trace amounts (< 0.1%) of 11 constituents were representing about 0.63% of the total oil content.…”
