I want to determine the amount of flavonoids in the licorice root. Analysis of the literature shows that for the quality of the standard is used liquirase or liquviritigenine. But I do not have standard samples. Can I use the quality of the quercetin standard to determine the amount of flavanoid sum in the licorice root?
Hi, yes you can.
Quercetin is a very well-known flavonoid and can be used as a standard sample in estimating the total flavonoid content (TFC).
Yes, you can use quercetin as a standard to estimate the total flavonoid content in licorice root in the absence of specific standards like liquiritigenin or isoliquiritigenin.
Good morning, although in the article presented I have not determined flavonoids, but if you can use quercetin as a pattern, there are scientific articles that mention about it, where they use the colorimetric method, greetings.
Yes, you can but the results will be expressed as quercetin equivalents and may not reflect the exact amount of specific flavonoids like liquiritigenin.
