Development of high-performance thin layer chromatography method for identification of phenolic compounds and quantification of rosmarinic acid conte…

2020

ABSTRACT Aim: Representatives of Nepetoideae Burnett subfamily are promising species of the Lamiaceae Martinov family because of accumulating such valuable groups of secondary metabolites as terpenoids and polyphenols. A high-performance thin layer chromatography (HPTLC) fingerprint method for the qualitative determination of phenolic compounds and for the quantification of rosmarinic acid (RA) content in methanol extracts of five species of this subfamily was developed for the first time. Materials and Methods: Dried aerial parts of Dracocephalum moldavica L., Ocimum americanum L., Lophanthus anisatus (Nutt.) Benth., Monarda fistulosa L., and Satureja hortensis L. collected in flowering pe…

The chemical composition of the aerial parts essential oil of Ammi crinitum Guss. (Apiaceae) endemic of Sicily (Italy)

2022

Ammi L. is a small genus of economically important plants belonging to Apiaceae family that includes only six taxa. In the present study the chemical composition of the essential oil from aerial parts of Ammi crinitum Guss., a very rare plant, endemic of Sicily, was analyzed by GC–MS. No previously paper has been published on this species. The results showed the presence of large quantity of monoterpene hydrocarbons with sabinene (63.9%), as the most abundant component. Other metabolites present in good quantity were γ-terpinene (8.0%), and 4-terpineol (3.7%). Based on the composition of the essential oil of all the other Ammi taxa, several considerations have been carried out.

Polyphenols and Pharmacological Screening of a Monarda fistulosa L. dry Extract Based on a Hydrodistilled Residue By-Product

2021

This study aimed to determine the composition and content of polyphenols in the dry extract obtained from the hydrodistilled residue by-product of the wild bergamot (Monarda fistulosa L., Lamiaceae Martinov family) herb (MFDE) and to evaluate its safety and pharmacological properties. The total phenolic content (TPC) in the MFDE was 120.64 mg GAE/g. The high-performance liquid chromatography (HPLC) analysis showed the presence of a plethora of phenolic compounds, including hydroxycinnamic acids and flavone derivatives in the MFDE, with rosmarinic acid and luteolin-7-O-glucoside being the main components. With an IC50 value of 0.285 mg/mL, it was found to be a strong DPPH radical scavenger. …

Comparison of essential oil components and in vitro anticancer activity in wild and cultivated Salvia verbenaca.

2015

The objectives of our research were to study the chemical composition and the in vitro anticancer effect of the essential oil of Salvia verbenaca growing in natural sites in comparison with those of cultivated (Sc) plants. The oil from wild (Sw) S. verbenaca presented hexadecanoic acid (23.1%) as the main constituent, while the oil from Sc plants contained high quantities of hexahydrofarnesyl acetone (9.7%), scarce in the natural oil (0.7%). The growth-inhibitory and proapoptotic effects of the essential oils from Sw and Sc S. verbenaca were evaluated in the human melanoma cell line M14, testing cell vitality, cell membrane integrity, genomic DNA fragmentation and caspase-3 activity. Both t…

A new species of Silene sect. Dipterosperma (Caryophyllaceae) from Sicily

2012

Silene kemoniana, a new species of the section Dipterosperma from NW Sicily, is described and illustrated. It is a therophyte that occurs in mountains near Palermo, where it grows on Mesozoic limestones in xerophilous garigues. Its relationships with S. colorata and allied species are also examined. A key of the species belonging to sect. Dipterosperma is provided. Se describe e ilustra Silene kemoniana, una nueva especie del NW de Sicilia perteneciente a la sección Dipterosperma. Se trata de un terófito que habita en algunas montañas próximas a Palermo, donde crece sobre calizas mesozoicas entre matorrales mediterráneos xerófilos. Se estudian sus relaciones con S. colorata y otras especies…

Cytotaxonomical investigation on Allium paniculatum ssp. exaltatum (Alliaceae) from Cyprus.

2004

Arare Allium endemic to Cyprus island, known as A. paniculatum subsp. exaltatum, is here examined. Relevant features in its morphology, caryology and leaf anatomy emphasize the marked taxonomic isolation of this taxon and allow it to be treated as a distinct species, proposed as Allium exaltatum. It is an exaploid plant (2n=48), probably arisen out of allopolyploidy and morphologically related only to some Middle East taxa.

Diversity in the population of Brassica incana Ten. (Cruciferae) in Sicily

2014

henotipic diversity in Sicilian populations of Brassica incana Ten. (Cruciferae) is here ana- lyzed in comparison with the only one known population of B. raimondoi Sciandrello et al., taxonomic close species recently described from the coastal relief of eastern Sicily. The analysis of diagnostic characters of these two taxa does not reveal significant differences that justify a treatment at species level of the population of B. raimondoi. On this base, the authors deemed to include this taxon in the infraspecific variability of B. incana and consider most appropriate the rank of subspecies. Therefore is here proposed the establishment of the trinomial com- bination B. incana subsp. raimond…

Neotrinia gen. nov. and Pennatherum sect. nov.in Achnatherum (Poaceae: Stipeae)

2019

Stipa splendens (syn. Achnatherum splendens) has been transferred to Neotrinia (Tzvelev) M. Nobis, P. Gudkovaet A. Nowak gen. nov.as N. splendens (Trin.) M. Nobis, P. Gudkova et A. Nowak, based on a comparison of the macromorphology and lemma micromorphology of the Asian representatives of the tribe Stipeae. Lemma epidermal patterns in the examined species are presented and discussed. Additionally, a new section Pennatherum M. Nobis comprising Achnatherum pelliotii, a species recently transferred to Achnatherum from Ptilagrostis is also proposed. This taxon clearly differs from Ptilagrostis by the lemma micromorphology. The species with typical maize-like lemma micromorphological pattern is…
