A New Acylated Flavonol Glycoside from Chenopodium foliosum
A new acylated flavonol glycoside, namely gomphrenol-3-O-(5'''-O-E-feruloyl)-β-D-apiofuranosyl(1→2)[β-D-glucopyranosyl-(1→6)]-β-D-glucopyranoside (1) was isolated from the aerial parts of Chenopodium foliosum Asch. The structure of 1 was determined by means of spectroscopic methods (1D and 2D NMR, UV, IR, and HRESIMS). Radical scavenging and antioxidant activities of 1 were established using DP...

علف هرزکاتوس از مهم‌ترین عوامل محدود‌کننده کشت نیشکر می‌باشد. به منظور تعیین کارایی علف‌کش ایندازیفلم در مقایسه با سایر علف‌کش‌های مورد کاربرد در نیشکر بر مهار علف هرزکاتوس، آزمایشی در قالب طرح بلوک‌های کامل تصادفی با 7 تیمار و چهار تکرار در یکی از مزارع پلنت منطقه شعیبیه شوشتر درسال96-1395 انجام شد. تیمارهای آزمایشی در این مطالعه شامل کاربرد علف‌کش <...
متن کاملAcylated flavonol glycosides from the flower of Inula britannica.
Three new acylated flavonol glycosides, patuletin 7-O-(6' '-isobutyryl)glucoside (1), patuletin 7-O-[6' '-(2-methylbutyryl)]glucoside (2), and patuletin 7-O-(6' '-isovaleryl)glucoside (3), were isolated from the n-BuOH extract of Inula britannica flowers by bioassay-guided fractionation, together with other known flavonoids. The structures were elucidated by 1D and 2D NMR, FABMS, and other spec...
متن کاملAntidiabetic and antioxidant activities of major flavonoids of Cynanchum acutum L. (Asclepiadaceae) growing in Egypt.
Seven flavonoids were isolated from the butanol fraction of the methanolic extract of the aerial parts of Cynanchum acutum L. (Asclepiadaceae). All of which have been isolated for the first time from the genus Cynanchum. Their structures were established as quercetin 3-O-beta-galacturonopyranoside (1), quercetin 7-O-beta-glucopyranoside (2), tamarixtin 3-O-beta-galacturonopyranoside (3), kaempf...
