“…Extraction temperature and static extraction time were independent factors during subcritical water extraction ( Table 1). The effect of independent factors on system response was determined by changing the level of one factor and keeping the other factors constant and, it was also reported by Ç am and Hışıl [13] and Ö zkaynak Kanmaz and Ova [3]. The aim of this study was to investigate the effect of material type (different food by-products), extraction temperature (50, 100, 120, 140, 160, 180, 200°C) and static extraction time (5, 15, 30, 45 min) on 5-HMF formation during subcritical water extraction.…”

“…So, apolar compounds can be extracted with pressurized hot water or subcritical water [1,2]. In the literature, it was reported that various phenolic compounds and other antioxidant compounds were extracted from plants, foods and food-by products with subcritical water [1,[3][4][5][6][7].…”

“…Because of that, material type is an important factor to form corresponding 5-HMF during subcritical water extraction. Besides, extraction temperature is the most important parameter during subcritical water extraction of bioactive compounds and also, static extraction time is an effective parameter to extract bioactive compounds with subcritical water [3,4,13].…”

The aim of this study was to investigate the effect of material type (artichoke leave, lemon peel, flaxseed meal), extraction temperature (50, 100, 120, 140, 160, 180, 200 °C) and static extraction time (5, 15, 30, 45 min) on 5-hydroxymethylfurfural (5-HMF) formation during subcritical water extraction. 5-HMF content of artichoke leave and lemon peel extracts increased 7.2 and 26.1 times with the rise of extraction temperature from 160 to 180 °C for 5 min during subcritical water extraction, respectively. Besides, 5-HMF content of artichoke leave, lemon peel and flaxseed meal extracts increased 1.4, 2.0 and 4.5 times as static extraction time increased from 15 to 45 min at 180 °C during subcritical water extraction, respectively. The highest 5-HMF content of artichoke leave and lemon peel extracts were obtained as 58.83 and 231.21 mg/L at 180 °C and 45 min, respectively. However, for flaxseed meal, the highest 5-HMF content (222.94 mg/L) was obtained at 200 °C and 15 min during subcritical water extraction.

“…These values were similar to those obtained by other authors. Kanmaz and Ova (2013) reported 12.9 mg g −1 of SDG dry weight (d. w.). Chen et al (2007) observed between 5.7 and 13 mg g −1 of SDG in flaxseed from the Gansu province, China.…”

“…Other technique includes the use of supercritical CO 2 for lignan extraction from flaxseed which results in lower SDG extraction compared to the traditional solvent extractions (Comin, Temelli, & Saldaña, 2011). However, supercritical water is suitable for SDG extraction from flaxseed (Kanmaz & Ova, 2013).…”

Optimization of secoisolariciresinol diglucoside extraction from flaxseed (Linum usitatissimum L.) and isolation by a simple HPLC-UV method Optimización de la extracción de secoisolariciresinol diglucósido desde linaza (Linum usitatissimum L.) y su purificación a través de un método simple HPLC-UV This research was conducted to develop and optimize a methodology to quantify the content of secoisolariciresinol diglucoside (SDG), the main vegetable lignan present in flaxseed. However, at the time of this work, commercial SDG was not available for standard use. Therefore, an effective method to obtain purified SDG from flaxseed was developed using chromatographic techniques. The SDG obtained was of approximately 97% purity. The methanol extraction time, alkali concentrations, and reaction temperature were optimized through a response surface methodology (RSM), and the optimal conditions established for the extractions were 47°C, 58 mmol L −1 sodium methoxide, and 24 h. This methodology was then applied to study the variation of SDG content in flaxseed from different cultivars. The SDG content in different varieties of flaxseed ranged from 10.8 to 17.9 mg g −1 in defatted flaxseed flour and from 6.0 to 10.9 mg g −1 in whole flaxseed.Keywords: flaxseed; lignan; secoisolariciresinol diglucoside; RSM El objetivo de esta investigación fue desarrollar y optimizar una metodología para cuantificar el contenido de secoisolariciresinol diglucósido (SDG), el cual es el principal lignano vegetal presente en linaza. Sin embargo, al realizar este trabajo no existía SDG comercial para ser utilizado como estándar externo. Por lo tanto, se desarrolló un método efectivo para obtener SDG purificado usando técnicas cromatográficas. El SDG obtenido fue de 97% de pureza. Se optimizó el tiempo de extracción metanólica, concentración de alcali y temperatura de reacción a través de un diseño de superficie respuesta. Las condiciones óptimas establecidas fueron: 47°C, 58 mmol L −1 de metóxido de sodio y 24 h. Esta metodología luego fue aplicada para estudiar la variación del contenido de SDG en linaza de diferentes cultivares. El contenido de SDG en diferentes variedades de linaza se encontró en el rango de 10,8 a 17,9 mg g −1 en harina desgrasada de linaza y de 6,0 a 10,9 mg g −1 en linaza entera.
