Edible flowers are receiving renewed interest as rich sources of bioactive compounds. Ethanol extracts of eight edible flowers were phytochemically characterized and investigated for their bioactivity. Rutin, quercetin, luteolin, kaempferol, and myricetin were selected as standards and quantified by HPLC. The fatty acids profile was analysed by GC and GC-MS. Antioxidant properties were evaluated by using different in vitro tests. The hypoglycaemic effects were investigated via the inhibition of alpha-amylase and alpha-glucosidase. S. nigra exhibited the highest radical scavenging activity (IC50 of 1.4 microg/mL), followed by H. coronarium (IC50 of 1.6 microg/mL). Both species contained high quercetin and rutin content. S. nigra extract exerted the highest activity in preventing lipid oxidation. M. sylvestris extract inhibited bothalpha-amylase and alpha-glucosidase with IC50 values of 7.8 and 11.3 microg/mL, respectively. These findings support the consumption of edible flowers as functional foods and their use as sources of natural antioxidants by food industry.
This research output has an Altmetric Attention Score of 5. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 June 2019.
All research outputs

of 34,400,738 outputs
Outputs from Journal of Agricultural & Food Chemistry
#9,717
of 25,829 outputs
Outputs of similar age
#93,206
of 302,276 outputs
Outputs of similar age from Journal of Agricultural & Food Chemistry
#66
of 201 outputs
Altmetric has tracked 34,400,738 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
So far Altmetric has tracked 25,829 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.2. This one has gotten more attention than average, scoring higher than 62% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 302,276 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
We're also able to compare this research output to 201 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
