Chemical composition and antibacterial effect of Smyrnium olusatrum L. Fruit Essential Oil
2020
The plants of the <em>Apiaceae</em> family are mainly used for food purposes and their multiple therapeutic properties and biological activities. This study aims to determine the chemical composition of Essential Oil (EO) of the fruits of <em>Smyrnium olusatrum</em> L. obtained by hydrodistillation in Clevenger-type apparatus. GC/MS analyzed the EO and the antibacterial activity was evaluated against clinical bacterial strains by two complementary methods (Disc diffusion and micro-atmosphere) and determination of Minimal Inhibitory Concentration (MIC). The results of chemical composition show that the EO is dominated by hydrocarbon monoterpenes (55,95%). The antibact…
The Essential Oil Composition ofEryngium foetidumL. in South Vietnam Extracted by Hydrodistillation under Conventional Heating and Microwave Irradiat…
2008
Abstract Essential oils of Eryngium foetidum L. (Apiaceae) in the South Vietnam isolated by hydrodistillation under conventional heating or microwave irradiation showed somewhat similar in chemical compositions. The microwave method gave a higher extraction yield in a much shorter time frame than the conventional heating protocol. Noticeably, the oil obtained from the microwave method showed a stronger antimicrobial activity than the other. Among all parts of the plant, inflorescence contained the highest oil content, and three-month old plant material was found richest in oil content as well. Physical, chemical and antibacterial properties of the oil products isolated from both methods wer…
The Diterpenoids of the Genus Elaeoselinum (Apiaceae) and their Biological Properties
2008
The natural kaurane, beyerane and atisane diterpenoids isolated from the genus Elaeoselinum (Apiaceae)and their semi-synthetic derivatives are reviewed. Published 13C NMR spectroscopic data and biological properties of these diterpenes are also reported.
Chemical Composition of Essential Oils from Athamanta sicula
2008
The genus Athamanta L. (Apiaceae) consists of about nine species, which are distributed mainly in southeastern Europe. Some of the Athamanta species are used in traditional medicine as antiseptics, diuretics, and in the therapy of sclerosis [1]. Phytochemical studies of species from the genus Athamanta report the presence of coumarins [2–5], flavonoids [6], and fatty acids [7]. Athamanta sicula L. is an annual perennial herb, growing to a height of 30 to 100 cm. It occurs in calcareous vertical cliffs 100 meters to 1500 meters above sea level and is widespread in South Italy, particularly in Sicily. In the popular medicine, it is known as “spaccapietre” (rock splitters), and infusions of it…
Coumarins from Seseli bocconi
1986
Abstract A new khellactone, bocconin, in addition to known compounds, have been isolated from Seseli bocconi subsp. bocconi and subsp. praecox Gamisans . Their structures were elucidated on the basis of spectral analyses and hydrolytic studies.

The Application of the Essential Oils of Thymus vulgaris L. and Crithmum maritimum L. as Biocidal on Two Tholu Bommalu Indian Leather Puppets
2021
The chemical profile of the Thymus vulgaris (Lamiaceae) essential oil (EO) was investigated in order to evaluate its biological properties against microorganisms affecting two Tholu Bommalu, typical Indian leather puppets stored at the International Puppets Museum “Antonio Pasqualino” of Palermo, Italy. A GC–MS analysis, using both polar and apolar columns, was used to determine the chemical composition of the essential oil. The aim of this study was to evaluate the antimicrobial effectiveness of the Thymus vulgaris and Crithmum maritimum essential oils in vapor phase to disinfect heritage leather puppets. Pieces of leather artifacts that were affected by different bacterial colonies were e…
Chemical Composition of the Essential Oils of Three Species of the Apiaceae Family Growing Wild in Sicily: Bonannia graeca, Eryngium maritimum and Op…
2013
n the present study the chemical composition of the essential oils from aerial parts of Bonannia graeca (L.) Halácsy and Opopanax chironium (L.) Kock, and from aerial parts and roots of Eryngium maritimum L. was evaluated by GC and GC-MS. α-Pinene (15.2%) and β-pinene were recognized as the main constituents of B. graeca, whereas the aerial parts of O. chironium contained mainly the diterpene cembrene and the coumarin angelicin. In both aerial parts and roots of E. maritimum germacrene D (10.4% and 15.9%, respectively) and 2,4,5-trimethylbenzaldehyde (8.3% and 6.7%) were the most abundant components
Andromonoecy and developmental plasticity in Chaerophyllum bulbosum (Apiaceae–Apioideae)
2013
Background and Aims: Andromonoecy, the presence of hermaphrodite and male flowers in the same individual, is genetically fixed or induced, e.g. by fruit set. Little is known about the forces triggering andromonoecy in the Apiaceae. In the present study, a natural population of the protandrous Chaerophyllum bulbosum was investigated to elucidate architectural constraints and effects of resource reallocation. Methods: Three sets of plants (each n ¼ 15) were treated by hand pollination, pollinator exclusion and removal of low-order inflorescences. Fifteen untreated plants were left as controls. Key Results: Untreated plants produce umbels up to the third branch order, with increasing proportio…
On the chemical composition and nutritional value of Pleurotus taxa growing on Umbelliferous plants (Apiaceae)
2005
Unpublished data on the chemical composition and nutritional value of Pleurotus mushrooms, growing on Umbelliferous plants (Apiaceae), are here reported. Cultivated basidiomata of four different Pleurotus taxa were analyzed in order to evaluate the composition in lipids, sugars, nitrogen, water, vitamins, ashes, and energetic values. The results showed that Pleurotus mushrooms are suitable in every type of diet thanks to their low caloric content, gastronomic value, vitamins, and mineral salt contents. The presence of a high content of vitamin B(12) and riboflavin in Pleurotus nebrodensis is noteworthy.
