The effects of different nitrogen doses on dry weight yield, stevioside and rebaudioside A contents, yields were evaluated in stevia (Stevia rebaudiana Bertoni). This study was carried out at the Instituto Federal Catarinense, Rio do Sul (SC), Brazil, under decreasing photoperiods. randomized complete block design with four blocks five treatments (0, 65, 135, 200 270 kg ha-1 N) used. Variables ...

Two additional novel minor diterpene glycosides were isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. The structures of the new compounds were identified as 13-{β-D-glucopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-oxy} ent-kaur-16-en-19-oic acid {β-D-xylopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)]-O-β-D-glucupyranosyl-ester} (1), and 1...

BACKGROUND Stevia rebaudiana Bertoni has been used for the treatment of diabetes in, for example, Brazil, although a positive effect on antidiabetic and its complications has not been unequivocally demonstrated. This herb also has numerous therapeutic properties which have been proven safe and effective over hundreds of years. Streptozotocin is a potential source of oxidative stress that induce...

The present study was conducted to optimize the green house conditions for Propagation of Stevia rebaudiana cuttings. belonging family Asteraceae, is a native Brazil and Paraguay. Its leaves produced stevioside, an caloric natural sweetener. sweetness stevioside 150 -300 times greater than sucrose. Seeds were very small in size. Production through seeds not beneficial because viable germination...
