Inula graveolens

In this work, Essential oils extracted from roots and aerial parts of Inula graveolens by hydrodistillation and their fractions obtained by chromatographic simplification were first investigated for their chemical composition by GC-MS and then evaluated for the first time for thier repellency and contact toxicity properties against Tribolium castaneum adults. Twenty-eight compounds were identified in roots essential oil (REO), which accounted for 97.9% of the total oil composition, with modhephen-8-β-ol (24...

OBJECTIVE: Crude oil extracts, components of extracts, and ethanolic extracts of Inula graveolens possess various pharmacological activities on various cancer cells including antioxidative and antiproliferative effects. Aqueous extract of this species has not been investigated on the liquid malignancies and solid tumors with a high incidence of treatment refractoriness and poor survival outcomes such as glioblastoma and leukemia. Hence, the present study aimed to evaluate the cytotoxic efficiency of I...

Inula graveolens (L.) Desf. is an annual aromatic herb which has various uses on alternative medicine in many region of the world. In this study, antioxidant activities of ethanol and water extracts of the plant leaves were determined by in vitro DPPH method and phenolic composition of the plant sample was determined by LC-MS/MS analysis. The results showed that chlorogenic acid, quinic acid, hyperoside, protocatechuic acid and quercetin were the major phenolic compounds among the 27 standard compounds. The significant antioxidant capacity of the plant might be related with the high abundance of phenolic compounds...

Diabetes represents a group of common diseases that are characterized by dysregulation of blood glucose levels. Plants are traditionally used for management of diseases including diabetes. In this study, we screened the anti-diabetic effect of extracts of 21 plants grown in Jordan. Extracts of plants were screened for their antihyperglycemic activity. Diabetes was induced in Sprague Dawley rats using Alloxan. Plant extracts were dosed at 1gm/kg. Blood glucose was measured at baseline and at every hour for 3 hours...

Inula graveolens is a poisonous annual plant of Mediterranean origin. The invasive nature of the plant suggests that it may possess phytotoxic activity. The aim of this study was to assess the ability of I. graveolens to inhibit the growth of different plants in Petri dish and to identify the main bioactive compounds. Bio-guided fractionation of the plant extracts led to the isolation of 2,3,11β,13-tetrahydroaromaticin (THA) and ilicic acid. Both compounds showed selective and significant phytotoxic activity at 25 ppm...

CONTEXT: Natural flora are considered a major source of new agents for the treatment of Helicobactor pylori. The plants used in this study were selected based on previous traditional use. OBJECTIVE: In this study, we evaluated the effect of extracts of 16 medicinal plants grown in Jordan against clinical isolates of H. pylori. MATERIALS AND METHODS: Tested plant extracts included Aloysia triphylla (L'Her.) Britton (Verbenaceae), Anethum graveolens L...

UNLABELLED: The aim of this work was to find an alternative to chemical fungicides currently used in the control of postharvest citrus fruit diseases. In this study, we screened eight Moroccan medicinal and aromatic plants extracted with petroleum ether, chloroform, ethyl acetate and methanol for their anti-fungal activity against Penicillium italicum, the causal agent of citrus blue mould. The anti-fungal activity of these extracts was tested based on the disc diffusion method. Petroleum ether extracts of Inula viscosa, Asteriscus graveolens, Bubonium odorum and Thymus leptobotrys and chloroformic extract of Anvillea radiata revealed the highest significant anti-fungal activity with inhibition zones that ranged between 25·83 and 28·33 mm in diameter...

This study was conducted to evaluate the antibacterial activity of Inula graveolens and Santolina corsica essential oils on Staphylococcus aureus and investigate their effects at the cellular level. The mode of inhibition of both essential oils against S. aureus ATCC 6538P (CIP 53.156) was assessed by determining the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). The effects of time and treatment dose on cell viability were determined by time-kill and bacteriolysis assays...

Commercially available essential oils extracted from Artemisia dracunculus L., Inula graveolens L., Lavandula officinalis Chaix, and Ocimum sanctum L. and the components of these oils were screened by the microplate assay method for determining their acetylcholinesterase (AChE) inhibitory activity. The composition profiles of the oils were characterized by gas chromatography-mass spectrometry (GC-MS) analysis, and the relationships between the oil components and the AChE inhibitory activity of the oils were outlined...

In bioassay-guided searches for novel bioactive natural products from higher plants of the Egyptian flora, two new eudesmane sesquiterpene derivatives, 3alpha-hydroxyilicic acid methyl ester (1) and 2alpha-hydroxy-4-epi-ilicic acid (2), together with 11 known sesquiterpenes were isolated from bioactive fractions of the active epigeal parts extracts of Dittrichia graveolens (L.) GREUTER (Asteraceae) growing in the coastal regions of northwestern Egypt. Four other known sesquiterpene lactones with different carbon skeletons, named 2alpha-hydroxy-2R-xanthalongin (8), 4-epi-isoinuviscolide (9), 8-epi-helenalin (10), and bigelovin (11), were also isolated for the first time from the same source...

The enantiomeric differentiation of bornyl acetate was carried out by 13C-NMR spectroscopy using a chiral lanthanide shift reagent. The technique was successfully applied to the determination of the enantiomer of bornyl acetate present in the essential oil of Inula graveolens.

The ascaricidal efficacy of six commonly used traditional herbs. Artemesia santonica, Inula helenium, Cassia abutnsifolla, Albizzia lebbek, Acacia auriculoformis and oil of Apium graveolens, was tested in vitro against the eggs and larvae of Ascaris lumbricoides. Aqueous extracts of 1% Artemesia and 5% of Albizzia and Inula were effective in killing both the infective larvae ill less than 40 days and eggs in 20 days. The results showed that Artemesia, Albizzia and to less extent Inula were promising antihelmintics against Ascaris lumbricoides...

Diarrhoea and mortality in sheep on a farm in the Winter Rainfall area of the Republic of South Africa were found to be due to an enteritis produced by the massive penetration of the mucous membrane of the small intestine by the bristles of the pappus of the Cape Khakiweed.
