General description
Steviol, a diterpenoiic carboxylic alcohol is an aglycone of sweet glycosides which is accumulated in Stevia rebaudiana. ent-kaurenoic acident-KA undergoes hydroxylation reaction in presence of molecular oxygen and NADPH, to yield steviol.
Application
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Steviol may have been used as reference standard to compare retention time and UV spectra in HPLC analysis for the quantification of steviol in Aconitum heterophyllum plant extract.

The diterpenoic compound steviol (ent-kaur-16-en-13-ol-19-oic acid) is the aglycone of sweet glycosides accumulated in Stevia rebaudiana Bertoni. This compound is the hydroxylated form of ent-kaurenoic acid (ent-kaur-16-en-19-oic acid; ent-KA). The hydroxylation of ent-KA to form steviol requiring NADPH and molecular
