Callus Induction and Cellular Suspensions from Murtilla (<i>Ugni molinae</i> Turcz.) for <i>trans</i>-resveratrol Production

“…Under these conditions retention times were 17.4 min for t-R and 14.1 min for t-P. The plant material extracts were analyzed by HPLC according to the methodology by Vitrac et al (2002) …”

“…In all these studies, concentrations varied depending on genotype and sample collection area. Some authors have explained that this phenomenon may be due to the attribution of abiotic or biotic stress factors from the surrounding environment, time of harvesting, climatic conditions, geographic origin, plant development and even crop type (organic, wild or agricultural) (Vitrac et al, 2002;Li et al, 2006). The comparative studies between in vivo and in vitro material (calli) to quantify secondary metabolites have been conducted for species like Vaccinium macrosporum and Buddleja cordata (Madhavi et al, 1995;Estrada-Zuniga et al, 2009).…”

Results of potentiometric and optical properties of shabo terroir wines

“…Как известно, для оценки состояния фенольных ве-ществ в столовых виноматериалах определяют следу-ющие показатели: ∆Eh -абсолютный прирост ОВ-по-тенциала: ∆Eh=Eh 1 -Eh 2 , где Eh 1 и Eh 2 , -начальное и конечное значение потенциала виноматериала или вина до и после титрования раствором йода соот-ветственно, мВ; ω -удельный прирост потенциала, рассчитываемый как частное от деления прироста по-тенциала ∆Eh на количество йода 1M (см 3 ), пошедшего на титрование: ω=∆Eh/1M; W -показатель окисляемо-сти, характеризует состояние окисленности феноль-ных веществ в винограде [5][6][7].…”
