CNS depressant effects, anti-inflammatory activity and anti-cholinergic actions ofSantolina chamaecyparissus extracts
1988
The pharmacological activity of several extracts together with the lyophilized infusion of S. chamaecyparissus ssp. squarrosa were investigated. The lethal dose 50% (LD50), effect on animal metabolism, mechanical and thermic analgesia and spontaneous, anti-inflammatory, and anti-ulcer activity have been determined. Studies on isolated organs (rat duodenum and rat uterus) were also carried out. The hexanic and chloroformic extracts were potent antagonists of the thermic analgesia test; the former extract was also active in the mechanical analgesia test. The chloroformic extract and, to a lesser extent, the ethyl acetate extract and lyophilized infusion demonstrated noteworthy activity as ant…
Orobanche apuana (Orobanchaceae) a new species endemic to Italy
2015
Orobanche apuana , a new species belonging to Orobanche sect. Orobanche , is described and illustrated from the Apuan Alps, Central Italy. Its relationships with the other species of the group of O. caryophyllacea ( O . grex Galeatae ) and with other Orobanche that parasitize Santolina species are examined. The names Boulardia latisquama , Orobanche lutea and O. teucrii are here lectotypified.
Oxygenated germacranes from Santolina chamaecyparissus
1993
The polar fraction of an extract of Santolina chamaecyparissus ssp. squarrosa yielded six new germacrane derivatives and a novel seco-germacrane lactone. The structures have been derived from spectral data, X-ray diffraction and chemical correlations.
<i>Santolina ageratifolia</i> Bamades ex Asso (<i>Compositae</i>) and their relationships with <i>S. rosmarinifolia<…
1997
The status of Santolina ageratifolia Bamades ex Asso as a distinct species belonging to S. rosmarinifolia L. aggr. is vindicated. An historical approach, a revision of the diagnostic characters and a detailed chorology of the species in Spain is presented. Likewise, some doubtful questions conceming taxonomy and chorology in Spain of the whole aggregate (including S. rosmarinifolia L. s. str., S. canescens Lag., S. pectinata Lag. and S. semidentata Hoffmanns. & Link) are clarified. A new nomenclatural combination is proposed: S. semidentata subsp. melidensis (Rodriguez-Oubina & Ortiz) Lopez Udias, Fabregat & Mateo.
Control of Erigeron bonariensis with Thymbra capitata, Mentha piperita, Eucalyptus camaldulensis, and Santolina chamaecyparissus Essential Oils
2020
In the search of sustainable and environmentally friendly methods for weed control, there is increasing interest in essential oils (EOs) as an approach to reduce synthetic herbicide use. The phytotoxicity of Thymbra capitata, Mentha piperita, Eucalyptus camaldulensis, and Santolina chamaecyparissus EOs against the noxious weed Erigeron bonariensis were evaluated in pre- and post-emergence assays in greenhouse conditions. The EOs were applied at 2, 4, and 8 µ
Germacrane derivatives from Santolina chamaecyparissus
1991
Abstract The aerial parts of Santolina chamaecyparissus subsp. squarrosa yieleded five new germacrane derivatives and a known eudesmane dialcohol.
Faceted phospholipid vesicles tailored for the delivery of Santolina insularis essential oil to the skin
2015
The aim of this work was to formulate Santolina insularis essential oil-loaded nanocarriers, namely Penetration Enhancer containing Vesicles (PEVs), evaluate the physico-chemical features and stability, and gain insights into their ability to deliver the oil to the skin.S. insularis essential oil was obtained by steam distillation, and was predominantly composed of terpenes, the most abundant being β-phellandrene (22.6%), myrcene (11.4%) and curcumenes (12.1%). Vesicles were prepared using phosphatidylcholine, and ethylene or propylene glycol were added to the water phase (10% (v/v)) to improve vesicle performances as delivery systems. Vesicles were deeply characterized by light scattering,…
Isolation and identification of an antiinflammatory principle from santolina chamaecyparissus
1989
The chloroform extract from Santolina chamaecyparissus squarrosa exhibited a potent anti-inflammatory effect on carrageenan-induced oedema in the rat hind paw. β-Sytosteryl 3-β-D-glucoside, isolated by fractionating this extract, was anti-inflammatory in the above test, with intraperitoneal and oral ED50 values of 70 and 146 mg/kg, respectively.
Anti-phospholipase A2 and anti-inflammatory activity of Santolina chamaecyparissus
2000
The activity of the Santolina chamaecyparissus methanol extract was tested against the phospholipase A2 (PLA2)-induced mouse paw edema and in vitro inhibition of PLA2 activity. After fractionation, only the dichloromethane extract was active against the PLA2 in vitro test. In addition, it reduced the edema induced by arachidonic acid, and by 12-O-tetradecanoylphorbol-13-acetate in a multidose test. After chromatography on silicagel and gel filtration on Sephadex, and using an in vitro anti-PLA2 assay-guided process, we have isolated and identified from the dichloromethane extract the flavone nepetin and four sesquiterpenes.
El género <i>Lysaphidus</i> (Hymenoptera: Braconidae) en la Península Ibérica
1995
The genus Lysaphidus Smith, 1944 (Hymenoptera, Braconidae, Aphidiinae) is recorded for the first time from the Iberian Peninsula represented by two species: L. arvensis Stary, 1960, first record for the Iberian Peninsula, and L. santolinae n. sp., both of them parasitoids of Coloradoa Wilson,1910 genus (Homoptera, Aphididae). The mummies were collected on Santolina chamaecyparissus L. and Santolina rosmarinifolia L. (Asteraceae).
