Opis:
Stevia rebaudiana Bertoni is a perennial plant belonging to Asteraceae family and its leaves contain steviol glycosides (SGs) that are 150 to 300 times sweeter than sucrose. The sweeteners obtained from S. rebaudiana can be safely used by diabetics as insulin secretion is not required during digestion of this sweetener. As it has zero calories, it is also used in diet products. Adaptation studies for Stevia conducted in Antalya, Turkey have shown that the stevia plant could easily be cultivated as a perennial. However, the lack of a sustainable vegetative propagation method creates a significant problem for stevia production. In the generatively populations, homogeneity and therefore quality are decreased because of cross-pollination. Stevia, as a self-incompatible and cross-pollinated species, has been shown to have very high genetic diversity. Therefore, development of a sustainable in vitro propagation method to prevent genetic heterogeneity of selected varieties is crucial for stevia cultivation. The aim of this study was to evaluate 2 different gelling agents (plant agar and Gelrite) and 20 different growth regulators combinations. The results demonstrated an approximately 200-fold multiplication rate obtained within 13 weeks using MS medium supplemented with 0.5 mg·dm–3 BAP and 0.25 mg·dm–3 kinetin and solidified with Gelrite. Average stevioside and rebaudioside A contents in in vitro propagated plant samples were found to be 8.1% and 8.6%, respectively.

Opis:
Introduction: Steviol stevioside, which has been used in the production of food products as a low-calorie sweeten, is one of the main glycoside groups in the leaves of the Stevia plants. It is useful for human health. Objective: The main objection of the present study was to find out some major chemical compositions of the dried Stevia rebaudiana Bertoni leaves and an effective, affordable, and environmentally friendly method to reach the high extraction yield of total steviosides from them. Therefore, a novel extraction, ultrasound-assisted extraction (UAE), was carried out to extract total steviosides from dried leaves of S. rebaudiana plant with ethanol of 70% (v/v) as a solvent. Methods: Some major chemical compositions of the dried S. rebaudiana leaves were analyzed according to the AOAC (Association of Official Analytical Chemists) and total steviosides content (TSC) was measured by anthrone-sulphuric acid colorimetric assay with main influencing factors including material/solvent ratio, extraction temperature, and extraction time. Results: The results referred that some chemical compounds such as protein, lipid, fibre, sugar, etc. existed in this material. The best extraction conditions were the sample/solvent ratio of 1:100 (g/ml), extraction temperature of 75oC, and extraction time of 30 min. Conclusion: The highest amount of total steviosides content of 8.894 % was obtained at the optimal extraction condition. Consequently, these results demonstrated that the parameters of UAE were applied successfully for producing total glycosides.
