A comparative study of the antifungal activity of essential oils of Varronia cu...
Nizio, Daniela Aparecida de Castro; Blank, Arie Fitzgerald; Brito, Fabiany de Andrade; Gagliardi, Paulo Roberto; Alves, EduardoThis work aimed to compare the antifungal activity of the essential oil of Varronia curassavica obtained by hydrodistillation and microwave against the fungus Colletotrichum musae and verify the alterations caused by these extraction methods on the leaf surface. This study used four essential oil samples obtained by different methods, two by hydrodistillation [HD1 (1.0 L of water and 100 min.) and HD2 (2.0 L of...
Influence of storage temperatures and storage time of dry leaves on patchouli [...
Arrigoni-Blank, Maria de Fatima; Santos, Priscilla Santana; Blank, Arie Fitzgerald; Brito, Fabiany de Andrade; Andrade, Thiago MatosPatchouli [Pogostemon cablin (Blanco) Benth.] is a plant of the family Lamiaceae, widely used as an essential oil in the cosmetics and perfumery industry. This study aimed to evaluate the influence of storage time and temperature of dry leaves on the patchouli essential oil content and chemical composition. The experiment was performed in a completely randomized design in a 6x2x2 factorial scheme, testing stora...
Distillation methods affect the chemical composition of Varronia curassavica Ja...
Nizio, Daniela Aparecida de Castro; Blank, Arie Fitzgerald; Sampaio, Taís Santos; Brito, Fabiany de Andrade; Andrade, Thiago MatosThe objective of this work was to evaluate the chemical composition of essential oil from Varronia curassavica Jacq. obtained by microwave (MI) and hydrodistillation (HD) extraction methods. The MI method tested three powers (500, 600, and 700W), three distillation times (20, 30, and 40 min.), and three water volumes (0, 25, and 50 mL per sample). The HD method tested three distillation times (100, 120, and 140...
Essential oils of Myrcia lundiana Kiaersk and their major compounds show differ...
Alves, Mércia Freitas; Blank, Arie Fitzgerald; Gagliardi, Paulo Roberto; Arrigoni-Blank, Maria de Fátima; Nizio, Daniela Aparecida de CastroThe present study evaluated the antifungal activity of the essential oils of chemotypes of Myrcia lundiana and their major compounds on the fungi Fusarium pallidoroseum, Fusarium solani, and Colletotrichum musae. The essential oils were obtained by hydrodistillation and analyzed by GCMS/FID. For the evaluation of the antifungal activity, the essential oils and the major compounds were tested at the concentratio...
Molecular characterization of patchouli (Pogostemon spp) germplasm
Sandes, Silvio Santos; Zucchi, Maria Imaculada; Pinheiro, José Baldin; Bajay, Miklos Maximiliano; Batista, Carlos Eduardo de AraujoPatchouli [Pogostemon cablin (Blanco) Benth.] is an aromatic, herbaceous plant belonging to the Lamiaceae family native to Southeast Asia. Its leaves produce an essential oil regularly used by the perfume and cosmetics industries. However, since patchouli from the Philippines and India were described and named Pogostemon patchouli, there has been a divergence in the identity of these species. The objective of t...
Analysis of genetic diversity of a native population of Myrcia lundiana Kiaersk...
Alves, Mercia Freitas; Nizio, Daniela Aparecida de Castro; Brito, Fabiany de Andrade; Sampaio, Taís Santos; Muniz, Ana Veruska Cruz da SilvaMyrcia lundiana Kiaersk. is a tree of the family Myrtaceae found in tropical and subtropical areas of the southern hemisphere that produces essential oil. The aim of this study was to characterize the genetic diversity of M. lundiana plants from a native population of Parque Nacional de Itabaiana, using inter-simple sequence repeat molecular markers. Thirty-five primers were tested, 20 of which were polymorphic...
Genetic diversity analysis of Varronia curassavica Jacq. accessions using ISSR ...
Brito, Fabiany de Andrade; Nizio, Daniela Aparecida de Castro; Muniz, Ana Veruska Cruz da Silva; Diniz, Leandro Eugenio CardamoneVarronia curassavica Jacq. is a medicinal and aromatic plant from Brazil with significant economic importance. Studies on genetic diversity in active germplasm banks (AGB) are essential for conservation and breeding programs. The aim of this study was to analyze the genetic diversity of V. curassavica accessions of the AGB of Medicinal and Aromatic Plants of the Federal University of Sergipe (UFS), using inter-...
