“…Unfortunately, the relative stereochemistry of the stereogenic centers at C-7 and C-10 could not be ascertained by a NOESY experiment since, after running the HMBC spectra, compound 2 decomposed. In Figure 1 we tentatively report the stereochemistry at C-7 and C-10 by analogy with artalbic acid, co-occurring in the same species, and on the base of biogenetic hypothesis [14].…”

Phytochemical investigation of the CH 2 Cl 2 extract of the aerial parts of Artemisia alba Turra afforded one new irregular sesquiterpenoid, artemiric acid, and five known metabolites: hydroxydavanone, the coumarins isofraxidin and scopoletin, (6S*,7S*,10R*)-6,10-dimethyl-7,10-epoxyocta-11-enoic acid and artalbic acid. From the MeOH extract three flavonoids were identified: chrysoeriol, quercetin and isorhamnetin. The possible biogenetic pathways of artemiric and artalbic acids are discussed.

“…Dicaffeoylquinic acids are widely distributed through the representatives of the Asteraceae family and probably play significant role for their antioxidant activity. [14] The coumarins umbeliferone (5) and scopoletin (6) have been previously isolated from A. alba from Italy [7] as well as from A. lobeli [5] and A. incanescens JORD. [10] Flavonoids are the most thoroughly studied compounds in A. alba.…”

The aim of this study was to evaluate flower and leaf methanol extracts of Artemisia alba Turra for their total phenolic and flavonoid contents, antioxidant capacity and to investigate their phenolic composition. The flower extract was richer in total phenolics and flavonoids and possessed higher antioxidant activity through DPPH and ABTS assays. The UHPLC-PDA-MS analysis of the flower and leaf methanol extracts revealed similar phenolic profile and allowed identification of 31 phenolic compounds (flavonoids, coumarins, and phenolic acids) by comparison with the respective reference compounds or tentatively characterized by their chromatographic behavior, UV patterns, and MS fragmentations. The presence of hispidulin, jaceosidin, desmethoxycentaureidin, and dicaffeoyl esters of quinic acid in A. alba is reported herein for the first time. The distribution of flavonoids in A. alba from different origins was discussed from chemotaxonomic point of view.

“…As continuation of our researches on Sicilian plants (Maggio et al 2011;Maggio et al 2012;) we decided to investigate on the chemical composition and the biological activity against several microorganisms, including Bacillus cereus, Bacillus subtilis, Fusarium oxysporum and Aspergillus niger, species infesting textile historical material (Kamel et al 2014), of the essential oil of M. spinosa collected in Sicily. Considering that in addition to microorganisms using biochemical processes of degradation, may be found on textile materials microorganisms whose growth can be connected with the presence of substances added during the production process (adhesives, dyes, finiture, etc.…”

In this study the chemical composition of the essential oil from aerial parts of Moluccella spinosa L. collected in Sicily was evaluated by GC and GC-MS. The main components of M. spinosa L. were α-pinene (26.6%), caryophyllene oxide (16.8%) and β-caryophyllene (8.6%). A comparison with other studied oils of genus Moluccella is made. Antibacterial and antifungal activities against some microorganisms infesting historical textiles were also determined.
