Methiin was present in all investigated samples. In the genus Allium, methiin-dominated species (rarely used by man) were common, but the occurrence of the other cysteine sulphoxides was variable and was largely correlated with use as spices or vegetables. Two major chemical types (named according to the species where they occur) could be distinguished, and at least two more may be recognized. Isoalliin dominates in the widely used "onion-type", which includes chive (A. schoenoprasum) and top… Expand
Evaluation and comparison of bioactive substances in selected species of the genus Allium
TLDR
The content of bioactive substances, especially the content of total polyphenols and antioxidant activity in several species of the genus Allium, were evaluated at full maturity stages from Zohor (Slovak Republic). Expand
An overview of the biological activities of less known wild onions (genus Allium sect. Codonoprasum)
TLDR
In zebrafish models, A. flavum and A. carinatum drastically improved the activity of doxorubicin (Dox) against cancer cells, and the results of these rewieved studies are indicative of the multiple beneficial pharmacological activities of wild Allium species. Expand
Allium species from Central and Southwest Asia are rich sources of marasmin.
TLDR
Allium species of the subgenus Melanocrommyum, especially Allium suworowii, are also very rich in marasmin and could be considered as natural sources for the isolation of this compound. Expand
Molecular identification of Allium ochotense and Allium microdictyon using multiplex-PCR based on single nucleotide polymorphisms
TLDR
This study is the first to report a simple, rapid, and efficient method for discriminating A. ochotense and A. microdictyon, indicating the utility of species-specific markers in the development of conservation and breeding programs. Expand
Can Allium chemical chest be a source of anticancer compounds?
TLDR
Allium plants, mainly represented by Allium sativum (garlic) and Allium cepa (onion), have been consumed by humans since prehistoric times for their bioactivity, including anticancer effect; many of these compounds have been investigated in terms of their anticancer potential. Expand
A taxonomic revision of Allium (Alliaceae) in the Canadian prairie provinces.
TLDR
The taxonomy, rarity, and conservation status of Allium L. is revised for the Canadian prairie provinces, based on analyses of herbarium specimens and fieldwork, including new illustrations, information on nomenclatural types, synonymies, and chromosomal and ecological data. Expand
The genus Tulbaghia (Alliaceae)--a review of its ethnobotany, pharmacology, phytochemistry and conservation needs.
TLDR
In order to derive the much anticipated benefits from the species without compromising their conservation status, the use of different biotechnological approaches highlighted in this review will certainly guarantee their continuous availability. Expand
Flavor precursors and sensory-active sulfur compounds in alliaceae species native to South Africa and South America.
TLDR
It was found that the pool of cysteine derivatives present in these plants is remarkably very simple, with S-((methylthio)methyl)cysteine 4-oxide (marasmin) being the principal flavor precursor, typically accounting for 93-100% of the pool. Expand
Influence of cultivar and harvest time on the amounts of isoalliin and methiin in leek (Allium ampeloprasum var. porrum).
TLDR
The amounts of ACSO changed significantly during the growth season, indicating the importance of harvest at specific time moments, although there was still an effect of cultivar on the ACSO amounts. Expand
Compartmentation and localization of bioactive metabolites in different organs of Allium roylei
TLDR
Saponin was the key component involved in plant protection against pathogen in Allium roylei and demonstrated significant antifungal activity depending on the applied concentration. Expand
