Diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the humans and experimental animals. Due to the anti-diabetic and antioxidant activity of pelargonidin (PG), this research study was conducted to evaluate the efficacy of chronic oral PG on alleviating learning and memory disturbance in streptozotocin-diabetic rats. Male Wistar rats were divided into...

Background: Diabetes mellitus in some clinical cases is accompanied with hyperalgesia. In this study, we evaluated the possible beneficial effect of chronic pelargonidin (PG) treatment on hyperalgesia in streptozotocin (STZ)-diabetic neuropathic rat. Methods: Male Wistar rats (n = 56) were divided into seven groups, i.e. control, diabetic, PG-treated control, PG (single- and multiple-dose)-trea...

Nudicaulins are a group of indole alkaloid glycosides responsible for the color of yellow petals of Papaver nudicaule (Iceland poppy). The unique aglycone scaffold of these alkaloids attracted our interest as one of the most unusual flavonoid-indole hybrid structures that occur in nature. Stable isotope labeling experiments with sliced petals identified free indole, but not tryptamine or l-tryp...

The effects of six flavonoids viz., apigenin, genistein, morin, naringin, pelargonidin and quercetin on the susceptibility of low-density lipoprotein (LDL) to oxidative modification were investigated. Flavonoids were added to plasma and incubated for 3 hr at 37 degrees C, and the LDL fraction was separated by ultracentrifugation. Oxidizability of LDL was estimated by measuring conjugated diene ...

During the harvest season of two consecutive years, five strawberry cultivars ('Arosa', 'Elsanta', 'Marmolada', 'Miss' and 'Raurica'), grown in the continental part of the Republic of Croatia, were examined. Strawberry fruits quality was evaluated by individual phenol compounds, individual anthocyanins and fruit color. Fruits were harvested in three different periods. Analyzed strawberry cultiv...

Evidence suggests that a combination of oxidative stress, neuroinflammation and the formation of endogenous neurotoxins contribute to the underlying neuronal death associated with neurodegenerative diseases. In this study we have investigated the ability of the berry-derived flavonoids to protect against neuronal damage induced by neuroinflammation and the neurotoxin 5-S-cysteinyl-dopamine. The...
