Myrcia paivae O.Berg (Myrtaceae) Essential Oil, First Study of the Chemical Composition and Antioxidant Potential

Abstract

The Myrtaceae family is one of the most representative in the Amazon. Several species have high added-value pharmacological potential. In order to contribute to the knowledge of the aromatic profile of Myrtaceae species from the Amazon, the present study presents the first report on the productivity, chemical composition, and antioxidant profile of the essential oil (EO) of Myrcia paivae. Dry leaves of the species were submitted to hydrodistillation to obtain their EO. The EO performance was calculated on a moisture-free basis and the analysis of the chemical profile was carried out by GC/MS. The determination of the antioxidant capacity was assessed by means of the antioxidant capacity equivalent to the inhibition Trolox of the ABTS•+ and DPPH• radicals. The results indicate that EO performance was equivalent to 1.69%. As for the chemical composition, hydrocarbon monoterpenes were predominant in the sample (>77%); terpinolene (14.70%), α-phellandrene (14.69%), γ-terpinene (9.64%), sylvestrene (7.62%), α-thujene (6.46%), and α-pinene (6.39%) were the constituents with higher content. Regarding the antioxidant capacity, the results show that the EO presented good results in the inhibition of ABTS•+ (0.886 ± 0.226 mM L−1) and DPPH• (2.90 ± 0.083 mM L−1), which can be attributed to the high monoterpene content in the sample.

Potential Effects of Essential Oil from Plinia cauliflora (Mart.) Kausel on Leishmania: In Vivo, In Vitro, and In Silico Approaches

“…The extraction of PCEO via hydrodistillation provided a higher yield of essential oil (7.33% v/w) when compared to reports of other species of the same family, such as Myrciaria tenella, Calycorectes sellowianus [35], and Myrcia paivae [36]. The chemical characterization of crude essential oils has a pivotal role in identifying the major components and understanding their possible mechanism of action.…”

Exploring the Potential of Myrcia Genus Essential Oils: A Review of Biological Activities and Recent Advances

“…Monoterpenes are natural organic compounds that represent a large group in the field of chemistry [ 38 ]. In this study, it was possible to observe that this chemical class characterized the profile of the essential oils of Myrcia lundiana (MLUN19), M. lundiana (MLUN23), M. mollis , M. ovata , and M. Paivae [ 7 , 13 , 39 , 40 ].…”

“…De Moraes et al [ 7 ] reported the antioxidant activity of Myrcia floribunda and Myrcia sylvatica essential oil via ABTS •+ and DPPH • methods. The results of their study indicated that the essential oil (EO) of M. floribunda exhibited an ABTS •+ inhibition rate of 53.27 ± 8.27%, comparable to Trolox (45.74 ± 4.16%) in terms of antioxidant potential.…”

“…Plant species are capable of producing compounds such as terpenes, carotenoids, phenols, flavonoids, and anthocyanins, with antioxidant properties capable of neutralizing free radicals, which have a negative impact on the biological cells of living organisms [ 6 ]. Some species of the Myrtaceae family reported in the literature have exhibited strong antioxidant properties, which can be utilized in the pharmaceutical and cosmetic industries due to their antioxidant potential [ 3 , 7 , 8 ].…”

Chemical Constituents, Antioxidant, and Enzyme Inhibitory Activities Supported by In-Silico Study of n-Hexane Extract and Essential Oil of Guava Leaves

“…It is a diverse botanical family that comprises characteristic genera, including, but not limited to, Syzygium, Eucalyptus, Myricaria, Melaleuca, Eugenia, Myrtus, and Pisidium [14][15][16][17]. It has an economic potential value due to its pleasant sensory properties and bioactive constituents, and it is considered as a continuous source of antioxidant agents [18].…”
