From methanolic extract of aerial parts of Peucedanum ruthenicum M. Bieb (Apiaceae) collected from Mazandaran province of Iran, four flavonoids namely Isorhamnetin 3-0-rutinoside 1, rutin 2, quercetin 3, morin 4 and two phenolic acids namely caffeic acid 5 and p-coumaric acid 6 have been isolated by Paper Chromatography (PC) and crystallization. Their structures were elucidated by MS, 1H, 13C N...

This study aimed to investigate the potential use of anthocyanin Berberis crataegina DC. as a natural food coloring agent in industry. For this aim, ultrasound-assisted extraction (UAE) method was performed extract The effect ultrasound power (X1: 20-100%), temperature (X2: 20-60 °C), and time (X3: 10-20 min) on TPC TAC extracts were examined optimized by applying Box–Behnken experimental desig...

The concentration of anthocyanins in fruits of "Assaria" pomegranate, a sweet Portuguese cultivar typically grown in Algarve (south Portugal), was monitored during storage under different conditions. The fruits were exposed to cold storage ( $5^{\circ}$ C) after the following treatments: spraying with wax; spraying with $1.5$ % CaCl(2); spraying with wax and $1.5$ % CaCl(2); covering boxes with...

Plumeria rubra Linn of the family Apocynaceae is locally known in Malaysia as "Kemboja". It has been used by local traditional medicine practitioners for the treatment of arthritis-related disease. The LCMS/MS analysis of the methanol extract of flowers (PR-ME) showed that it contains 3-O-caffeyolquinic acid, 5-caffeoquinic acid, 1,3-dicaffeoquinic acid, chlorogenic acid, citric acid, 3,3-di-O-...

The purpose of this research is to investigate and identify polyphenolic complexes other biologically active compounds by tandem mass spectrometry, presented in the leaves stems Ledum palustre L. Carbon dioxide, compressed a supercritical state, was used for most environmentally friendly extraction effective characteristics (pressure 350 bar; temperature 60 °С; time 1-hour, co-solvent MeOH 3.5%...

BACKGROUND Ten genotypes representing two elderberry species, Sambucus canadensis L. (eight genotypes) and S. nigra L. (two genotypes), were examined for their anthocyanins (ACY), total phenolics (TP),°Brix, titratable acidity (TA), and pH over two growing seasons. RESULTS Overall, fruit generally had higher ACY, TP, ACY/TP,°Brix, and pH in 2005 than 2004. All samples of S. canadensis had sim...

A tannin, EA (1), and other nine non-tannins compounds, gallic acid (2), quercetin (3), myricetin (4), 3-O-methylellagic acid-4?-O-?-L-rhamnopyranoside (5), quercetin-3-O-?-D-galactopyranoside (6), kaempferol-3-O-?-D-glucoside (7), quercetin-3-O-?-D-glucuronide (8), quercetin-3-O-rutinoside (9), 3,3?,4-tri-O-methylellagic acid-4?-O-?-D-glucopyranosyl (10) were isolated from a valuable medicinal...
