Purpose: To evaluate the mechanism of antioxidant activity of the methanol extract of Codonopsis pilosula. Methods: Anti-oxidative properties were assessed by measuring free radical scavenging activity, nitric oxide (NO) levels, protein oxidation and reducing power, while the mechanism of antioxidative effect of Codonopsis pilosula extract was determined by measuring iNOS and COX-2 expression i...

We investigated the role of transcription factors (R, SN, C1, and PL) in the regulation of anthocyanin biosynthesis by different light qualities (white, red, blue, and ultraviolet) and by cytokinin in maize (Zea mays). We analyzed anthocyanin accumulation, structural gene expression, and regulatory gene expression in the seed aleurone and the seedling mesocotyl. In the mesocotyl, white, blue, a...

Solanum tuberosum L. cv Hongyoung (SH) is a widely consumed anthocyanin-rich food and medicinal plant, which possesses anti‑inflammatory and anti‑allergic activities. The present study aimed to examine the inhibitory effects of SH extract on atopic dermatitis (AD)‑like skin lesions induced by the topical application of 2,4‑dinitrochlorobenzene (DNCB) in NC/Nga mice. SH extract was orally admini...

dorema aucheri boiss. (apiaceae) is an endemic plant growing in iran. this plant is used as food and its extracts are recommended for the treatment of a wide range of diseases. to conduct this study, leaf, stem, and flower of d. aucheri were collected from near yasouje, iran. antioxidant and antimicrobialeffects of methanol extracts were measured. further, total phenolic,flavonoid, anthocyanin,...

in this investigation some chemical and morphological properties of dog rose fruit in 10 regions of north iran were measured. results showed significant difference between traits in studied regions. beta-carotene ranged between 0.05 – 0.323 (mg/g fw). total soluble carbohydrate varied from 5.9 – 23.3%. the highest content of total anthocyanin 23.7 and the lowest was 7.71(mg/l cyanidin-3-glucosi...

Anthocyanin is a critical factor involved in coloration of plant tissues, but the mechanism how medium pH values affect anthocyanin accumulation in woody plants is unknown. We analyzed anthocyanin composition and the expression of elements encoding anthocyanin and flavonols biosynthesis underlying different medium pH values by using three different leave color type cultivars. HPLC analysis demo...

To elucidate plant mechanisms involved in molybdenum (Mo) sequestration and tolerance, Brassica spp. seedlings were supplied with molybdate, and the effects on plant physiology, morphology, and biochemistry were analyzed. When supplied with (colorless) molybdate Indian mustard (Brassica juncea) seedlings accumulated water-soluble blue crystals in their peripheral cell layers. Energy dispersive ...

Vaccinium fruit ingredients within dietary supplements were identified by comparisons with anthocyanin analyses of known Vaccinium profiles (demonstration of anthocyanin fingerprinting). Available Vaccinium supplements were purchased and analyzed, their anthocyanin profiles (based on high-performance liquid chromatography [HPLC] separation) indicated if products' fruit origin listings were auth...

This study aimed to investigate the effect of six chloride salts on butterfly pea flower extract’s anthocyanins stability. The were NaCl, KCl, CaCl2, MgCl2, FeCl3, and AlCl3. samples analyzed using a UV-Vis spectrophotometer observe color degradation change in hue during storage. extraction was done modified method, solutions stored dark vials at room temperature. kinetics benzene derivatives, ...

A comparative study in Malva sylvestris L. plants was carried out for change in growth pattern and their anthocyanin production with various induced stress. Exogenous administration of 0.1mM concentration of abscisic acid, silver nitrate as foliar spray for five successive days and supplemental thirty minutes exposure dose of UV-B for continuous three days to the plants significantly induced va...
