“…Research into isosteviol and its derivative being used as a plant regulator, were carried out recently where the synthesized derivatives were tested on lettuce hypocotyl and barley aleurone bioassays. 17-hydroxy-16-ketobayeran-19-oic acid (17-hydroxyisosteviol, 6,16-ketobayeran-19-oic acid (isosteviol), 16,17-dihydroxybeyeran-19-oic acid, and 16-hydroxyiminobayeran-19-oic acid (isosteviol oxime) are the isosteviol moieties that were obtained by biotransformation of stevioside using Penicillium citrinum fungi [ 54 ]. The result of lettuce hypocotyl bioassay revealed that isosteviol was found to be more active than gibberellin acid at a concentration of <10 −9 M of the activity, however, decreased at highest concentration [ 54 ].…”

Steviosides, rebaudiosides and their analogues constitute a major class of naturally occurring biologically active diterpene compounds. The wide spectrum of pharmacological activity of this group of compounds has developed an interest among medicinal chemists to synthesize, purify, and analyze more selective and potent isosteviol derivatives. It has potential biological applications and improves the field of medicinal chemistry by designing novel drugs with the ability to cope against resistance developing diseases. The outstanding advancement in the design and synthesis of isosteviol and its derivative has proved its effectiveness and importance in the field of medicinal chemical research. The present review is an effort to integrate recently developed novel drugs syntheses from isosteviol and potentially active pharmacological importance of the isosteviol derivatives covering the recent advances.

“…Moreover, our results suggest that SVglys could prevent the destructive consequence of drought stress for stevia, but their precise mechanism has not been identified until now. However, the SVglys behavior may attribute to a hormonal result because the weak hormonal effect of SVglys derivatives has been suggested by researchers (Ruddat et al 1963;de Oliveira et al 2008). In addition, the maintenance of high water potential in plant cell is a vital mechanism for plant in overcoming the drought stress (Ingram & Bartels 1996;Farooq et al 2009) and soluble compounds like SVglys could be helpful in this operation.…”

Steviol glycosides (SVglys) are a group of diterpenoids mainly present in the leaves of stevia (Stevia rebaudiana Bertoni). An experiment was conducted to find the functional role of SVglys compounds in stevia affected by drought stress. In this study, a liquid blend of SVglys (200 ppm) was sprayed on stevia plants grown in well-watered (90% field capacity) and drought-stress conditions (45% field capacity) and then the morphological traits and metabolites were evaluated. It was observed that leaf losses caused by drought stress were stopped through external application of SVglys and consequently the harvest index of stevia was increased. Metabolite analysis of stevia leaves showed that the total SVglys content was significantly decreased due to drought stress, but was compensated by external application of SVglys. Among the SVglys, Rebaudioside A responded more to external SVglys. A slight promotion in total antioxidant activity of stevia leaves was observed when external SVglys was applied. The glucose availability in stevia leaves was increased by external application of SVglys but only in well-watered plants. According to our findings, it can be concluded that in stevia, SVglys may have a positive function in drought stress tolerance by exerting a protective role under such conditions.

“…It has been pharmaceutically used to improve cognitive functions including memory, alertness, learning, and psychotic stability. In addition, it has been used as a plant-growth factor (Ko et al, 2013;de Oliveira et al, 2008). It might also have potential antihyperglycemic effects on stimulating pancreatic beta cells to secrete insulin (Jeppesen et al, 2000).…”
