Chemical composition, phytotoxic potential, biological activities and antioxidant properties of Myrcia hatschbachii D. Legrand essential oil

Abstract

Myrcia hatschbachii D. Legrand (Myrtaceae) is a native and endemic species from Brazil. This study investigated the essential oil composition, phytotoxic potential, in vitro toxicity, antioxidant properties and antibacterial activity of species. Chromatographic analysis of essential oil identified trans-calamanene, (E)-caryophyllene and spathulenol as major components. Antioxidant capacity was determined by the DPPH• scavenging method and phosphomolybdenum complex formation assay. Antibacterial activity was evaluated using the Minimal Inhibitory Concentration test, demonstrating that the essential oil was active toward Enterococcus faecalis and Staphylococcus aureus. Phytotoxic activity of essential oil was analyzed by testing interference on germination and growth of Lactuca sativa, demonstrating significant inhibition of the hypocotyls and radicles of seeds. Preliminary toxicity studies were determined using Artemia salina, resulting in an LC 50 of 409.92 µg/mL, and through hemolytic activity. The results of the phytotoxic activity point to a possible application for Myrcia hatschbachii in the development of natural herbicides and the in vitro toxicity assays suggests the performance of antitumoral activity tests, having in mind the prospection of antineoplastic drugs.

Phytochemical Profile and Herbicidal (Phytotoxic), Antioxidants Potential of Essential Oils from Calycolpus goetheanus (Myrtaceae) Specimens, and in Silico Study

“…In both cases analyzed, we can see that, for this variable studied, receptor plant S. obtusifolia was the most affected by the EOs. The results of this study, when compared to the literature, do not follow the same pattern of response; for example, in previous studies, the most affected receptor species was M. pudica [ 59 , 60 ]; however, these response patterns depend on factors other than the receptor species, such as the chemical profile of the essential oil [ 60 , 61 , 62 , 63 ].…”

Chemical Composition and Antioxidant Activity of Essential Oils from Eugenia patrisii Vahl, E. punicifolia (Kunth) DC., and Myrcia tomentosa (Aubl.) DC., Leaf of Family Myrtaceae

“…Furthermore, specimen A of E. punicifolia exhibited higher antioxidant activity in the DPPH assays compared to the other specimens studied. This may be attributed to the presence of oxygenated compounds in their composition, as DPPH is more sensitive to polar substances [55]. Additionally, synergistic action between the chemical constituents may have contributed to the higher antioxidant activity observed [56].…”

Phytotoxic and Enzymatic Study of Philodendron meridionale on seeds of Lactuca sativa L.

“…The resistance or tolerance of secondary metabolites that serve as allelochemicals is becoming more and more defined and is found in more sensitive species than others, such as Lactuca sativa L. (lettuce) (Ferreira & Aquila, 2000;Reigosa et al, 2013). This is the most common plant used as a target species among hydrophytes, due to the short time required for germination (24 to 48 h) and growth (Elakovich, 1999, Gatto et al, 2020.…”
