Antioxidant Activity of Stevia rebaudiana

NIPPON SHOKUHIN KAGAKU KOGAKU KAISHI, 1998
ステビア茎粗抽出物は強い抗酸化活性を示した.その活性は抗酸化指数で葉に比べ5倍程度高く,現在ほとんど利用されていない茎の新たな利用価値を提示した.ステビア抽出末はマイワシ油およびリノール酸に対して100ppmの添加で抗酸化効果を発現した.その効果は同濃度のBHT,α-Tocに匹敵する強さを示した.ステビア抽出末はα-Tocおよびクエン酸を併用することにより抗酸化効果が増強された.ステビア抽出末の抗酸化有効成分は主として透析外液(分画分子量500)に存在した.外液濃縮物を逆相カラムクロマトグラフィー.薄層クロマトグラフィーで分画し,複数の有効画分を認めた.その多くは,ポリフェノール化合物であったが,最も強い効果を示した成分にはカリウムが高濃度で存在した.

A New Diterpene Glycoside from Stevia rebaudiana [PDF]

Molecules, 2011
From the commercial extract of the leaves of Stevia rebaudiana, a new diterpene glycoside was isolated besides the known steviol glycosides including stevioside, rebaudiosides A-F, rubusoside and dulcoside A. The new compound was identified as 13-[(2-O-β-D-glucopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-(2-O-α-L-

Green and Sustainable Synthesis of Silver and Gold Nanoparticles: A Stevia Leaf Extract Approach

Food Science &Nutrition, Volume 13, Issue 8, August 2025.
Stevia extracts offer a novel and environmentally friendly method for synthesizing silver (AgNPs) and gold (AuNPs) nanoparticles. The synthesized nanoparticles displayed characteristic surface plasmon resonance (SPR) in specific ranges and were confirmed to be spherical and well‐dispersed via TEM imaging.

Subcritical Fluid Extraction of Stevia Sweeteners from Stevia rebaudiana [PDF]

Journal of Chromatographic Science, 1997
In this paper, the extraction of steviol glycosides in Stevia rebaudiana, including stevioside, rebaudioside A, rebaudioside C, and dulcoside A by subcritical fluid extraction (SubFE) is investigated. A simple, efficient SubFE method is developed. The extraction conditions (extraction phase composition, extraction time, etc.) are optimized.
