Why do stevia plants have high concentration of ent kaurenoic acid?
Theoretically, in Stevia, if the genes responsible for production of ent Kaurenoic acid is enhanced or “over expressed”, that may result into high concentration of that ent Kaurenoic acid in the plant cells.
What are the chemical properties of stevia?
The active compounds are steviol glycosides (mainly stevioside and rebaudioside), which have about 50 to 300 times the sweetness of sugar, are heat-stable, pH-stable, and not fermentable. The human body does not metabolize the glycosides in stevia, so it contains zero calories as a non-nutritive sweetener.
What is the chemical in stevia that makes it sweet?
Scientists have crystallized the structure of the enzyme that adds glucosides to ribaudioside A, one of the main components of the sweetener stevia. Researchers have crystallized the enzyme that makes the natural product stevia taste 200 times as sweet as sugar.

How long does it take to analyze stevia leaves?
Stevia leave analysis of up to 21 samples took 13 min when separated up to a migration distance of 60 mm ( Fig. 5.2A) ( Morlock and Heil, 2020 ). Although 12 steviol glycosides were intended to be separated, a coeluting zone of rebaudioside D/M was evident. In such a case, HPTLC–HRMS was a helpful tool to prove which steviol glycoside was present ( Fig. 5.2B and C ). The elution of a zone took 0.5 min at a flow rate of 200 µL/min, plus 0.5 min rinsing time. The mass spectrometric detector was only used on-demand and highly targeted (not for the whole run including background and matrix, as for analysis of new samples in column techniques). As a new asset, in the steviol glycoside mixture, compounds were detectable as bright zones using the HPTLC– Aliivibrio fischeri bioassay, which was employed to obtain information on bioactive compounds in the Stevia leaf extracts ( Fig. 5.2D) ( Morlock and Heil, 2020 ). This bioanalytical tool (a combination of chromatographic separation with biological assay) was able to point to unknown active compounds. Such effect-directed detections are an attractive non-target tool for quality control and safety assessment of Stevia products along the global product chain ( Morlock, 2019 ).

In the EU steviol glycosides have been approved since 2011 for limited applications. There is a maximum usable dose of 330 mg/kg in essoblaten. In Japan and other Asian countries as well as in some South American countries it has been permitted for a longer time. Typical uses are Asian foodstuffs such as sauces and pickles, refreshing drinks, tabletop sweeteners and sweets. In the United States rebaudioside A-based natural sweeteners obtained a GRAS approval in 2008.
