Chemical composition and bio-functional perspectives of Erica arborea L. extracts obtained by different extraction techniques: Innovative insights

Procyanidins: From Agro-Industrial Waste to Food as Bioactive Molecules

“…Extraction obtaining bioactive compounds by the ultrasound method from agro-industrial residues has been widely reported [ 164 , 179 ]. However, few reports of procyanidin extraction have been reported in the last five years, and most studies have focused on the evaluation of different extraction conditions on the yields of bioactive compounds [ 164 , 180 , 181 , 182 , 183 , 184 , 185 , 186 ]. The mechanism of extraction occurs by mechanical vibration through waves that penetrate a liquid system and form gas bubbles [ 187 ].…”

Distribution of polyphenolic and sugar compounds in different buckwheat plant parts

“…† The compounds were conrmed using the standards and the previously published MS data. 27,31,35,[40][41][42][43][44][45][46][47][48][49][50][51] The frequency of phenolic compounds in the buckwheat sample extracts is presented as colour scale, which dened the intensity of the obtained peak area of one compound per sample (Fig. 2).…”

First Extensive Polyphenolic Profile of Erodium cicutarium with Novel Insights to Elemental Composition and Antioxidant Activity

“…[39] National and regional limits for arsenic and toxic metals in herbal medicines refer to crude herbal drugs and finished herbal products with limits in the range from 4 to 5 mg kg À 1 , where the limit for raw herbal materials in Canada is stated as 5 mg kg À 1 and a limit of 2 mg kg À 1 for herbal materials in China. [40,41] The National Sanitation Foundation draft proposal (Raw Dietary supplement) states the limit for arsenic to be 5 mg kg À 1 for other herbal products and the National Sanitation Foundation draft proposal (Finished Dietary Supplement) states the limit as 0.01 mg arsenic day À 1 . [38] The maximum amounts of metals in medicinal plant materials can also be given based on the ingested weekly basis, the so called Provisional Tolerable Weekly Intake (PTWI), and it is being proposed to be 15 μg kg À 1 b.w.…”

“…A Syncronis C 18 column (100 × 2.1 mm, 1.7 μm) thermostated at 40°C was used as the analytical column for separation. Chromatographic and mass spectrometry settings were as previously described in Zengin et al [41] The mobile phase consisted of (A) water + 0.1 % formic acid (V/V), and (B) 100 % acetonitrile (MS grade) + 0.1 % formic acid, which were applied in the following gradient elution: 5 % B in the first minute, 1.0 -16.0 min 5-95 % B, 16.0 -16.2 min from 95 % to 5 % B, and 5 % B until the 20 th min. The flow rate was set to 0.3 mL/min and injection volume was 5μL.…”
