Тhe aim of the study was identification and determination of the content of flavonoids in dry extracts of Teucrium polium, collected from Republic of Macedonia. Two different drying procedures were used, freeze and spray draying. In freeze-dried (FDE) and spray-dried (SDE) extracts of aerial parts of T. polium five flavone aglycones (luteolin, apigenin, cirsiliol, cirsimaritin and cirsilineol) ...
The migration of flavonoids from low-density polyethylene (LDPE) film (0.4%, w/w) to aqueous food simulants over 16 weeks at 0, 15, and 30 °C was investigated. The migration amount of total flavonoids was calculated based on the rutin contents determined by high-performance liquid chromatography (HPLC). Diffusion and partition coefficients, along with the activation energy (Ea) were calculated ...
The paper determined the content of total flavonoids in different types and parts rhizome shoot winter bamboo shoots by UV spectrophotometry for comparison. results showed that sheath had a higher level than shoots, parts.
Okra (Abelmoschus esculentus (L.) Moench), a healthy vegetable, is widely spread in tropical and subtropical areas. Previous studies have proven that okra pods possess anti-fatigue activity, and the aim of this research is to clarify the anti-fatigue constituents. To achieve this, we divided okra pods (OPD) into seeds (OSD) and skins (OSK), and compared the contents of total polysaccharides, to...
Propolis was used as medicine, cosmetic and beverage additives since past decades. The most important active compounds in the propolis are phenolic and flavonoids, which are in the resin category. The purpose of this study was to measure the total amount of flavonoids and quercetin in propolis of northern Iran and compare obtain data with different extraction methods. The soxhlet, maceration an...
