Root and Foot Rot of Lantana Caused by Phytophthora cryptogea
2005
Lantana (Lantana camara L.) is an evergreen shrub in the Verbenaceae. In some countries, this plant has been declared a noxious weed. However, a number of sterile or near-sterile forms are cultivated as attractive flowered potted and garden plants. In early spring 2004, ≈4,000 potted, small trees of lantana grown in a screenhouse in a commercial nursery of ornamentals near Giarre, Sicily, showed symptoms of chlorosis, defoliation, and sudden collapse of the entire plant. These aboveground symptoms were associated with a reduced root system, rot of feeder roots, and brown discoloration of the base of the stem. A Phytophthora sp. was isolated consistently from roots and basal stems of sympto…
Effectiveness of the Influence of Selected Essential Oils on the Growth of Parasitic Fusarium Isolated from Wheat Kernels from Central Europe
2021
The aim of the study was to determine the effectiveness of selected seven commercial essential oils (EsO) (grapefruit, lemongrass, tea tree (TTO), thyme, verbena, cajeput, and Litsea cubeba) on isolates of common Central European parasitic fungal species of Fusarium obtained from infected wheat kernels, and to evaluate the oils as potential natural fungicides. The study was conducted in 2 stages. At each stage, the fungicidal activity of EsO (with concentrations of 0.025
Evaluation of Fungistatic Activity of Eight Selected Essential Oils on Four Heterogeneous Fusarium Isolates Obtained from Cereal Grains in Southern P…
2020
The aim of the study was to determine the relationship between the chemical composition of eight commercial essential oils (EsO) (garlic, grapefruit, lemon grass, tea tree, thyme, verbena, cajeput, and Litsea cubeba) and their fungistatic activity in relation to four species of Fusarium: F. avenaceum, F. culmorum, F. graminearum, and F. oxysporum. The species identification of Fusarium isolates was confirmed by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometer. The determination of qualitative and quantitative chemical composition of the EsO was carried out using the gas chromatography&ndash
Chemical composition and biological activity of Salvia verbenaca essential oil
2011
Salvia verbenaca L. (syn. S. minore) is a perennial herb known in the traditional medicine of Sicily as “spaccapetri” and is used to resolve cases of kidney stones, chewing the fresh leaves or in decoction. The chemical composition of the essential oil obtained from aerial parts of S. verbenaca collected in Piano Battaglia (Sicily) on July 2009, was analyzed by GC and GC-MS. The oil was strongly characterized by fatty acids (39.5%) and carbonylic compounds (21.2%), with hexadecanoic acid (23.1%), ( Z)-9-octadecenoic acid (11.1%) and benzaldehyde (7.3%) as the main constituents. The in vitro activity of the essential oil against some microorganisms in comparison with chloramphenicol by the …
Structure and Synthesis of a New Indole Alkaloid, 19 (S)-Hydroxy-Nb-methylraumacline, Obtained by the Biotransformation of Ajmaline in Plant Cell Cul…
1992
Abstract From the plant cell suspension cultures of Tauwolfia serpentina Benth ., which were cultivated in the alkaloid-production medium after feeding of ajmaline (1) , a new indole alkaloid 19- ( S )-hydroxy- N b -methylraumacline ( 4 ) was isolated. The structure of 4 first elucidated by spectroscopic analysis was determined by the chemical synthesis from ajmaline ( 1 ).
Structural considerations on the iridoids as anti-inflammatory agents.
1994
Abstract Twelve iridoid glycosides have been evaluated for their anti-inflammatory activity on two models: the carrageenan-induced mouse paw edema and the TPA-induced mouse ear edema. Loganic acid was the most active (44.4% edema inhibition) on the former test, whereas the catalpol derivative mixture isolated from Scrophularia, aucubin, verbenalin, and loganin, showed the highest activity (from 72.0 to 80.0% edema inhibition) on the latter. The results allowed us to establish the relationship between the structure and anti-inflammatory activity on the basis of the different patterns of substitution, particularly hydroxylation, unsaturation, and acylation.

The Influence of Aroma Compounds on Senzorial Traits of Wines From the Apold Depression
2015
Abstract The present study aims at investigating aroma compounds in three wine varietals (Pinot gris, Traminer roz, Riesling) from Apold, the county of Sibiu, production of 2014, and their importance in realizing the sensorial profile of wines. Thus, it is ascertained that Traminer roz contains the highest amount of esters - 583.846 mg/L, a value that leads to the sensorial identification of floral and fruity notes. Higher alcohols determined through chromatography imprint specific traits to Pinot gris wines: bittersweet, floral notes validated through the determined amount (479.449 mg/L). Another wine trait is the concentration of higher fatty acids which reach an amount of 252.667 mg/L in…
Chemical Composition of the Leaf Oil ofLantana camara
2005
The essential oil of the fresh leaves of Lantana camera growing in Dehra Dun was analyzed by GC and GC/MS. The major constituents identified in the oil included β-caryophyllene (23.3%), α-humulene (11.5%), germacrene D (10.9%), davanone (7.3%) and γ-curcumene (6.3%).
