citrus unshiu/抗アレルギー

A study was carried out to examine the effect of 50% ethanolic extract from green fruit of Citrus unshiu Markovich on type I, II and IV allergic reactions. Forty eight-hour homologous passive cutaneous anaphylaxis (PCA) in rats as a typical model of the type I reaction was significantly inhibited by

In a bioassay-guided search for anti-allergic compounds from higher plants of Korea, polymethoxyflavones, 3',4',5,6,7,8-hexamethoxyflavone (1), 5-hydroxy-3',4',6,7,8-pentamethoxyflavone (II) and 3',4',5,7,8,-pentamethoxyflavone (III) have been isolated from the immature peels of Citrus unshiu.

A study was carried out to clarify the active component of green fruit of Citrus unshiu MAKOVICH on the type I allergic reaction. The flavonoid component, isolated from its methanolic extract, hesperidin, was found to inhibit histamine release from peritoneal mast cells of rats induced by compound

Effect of 50% ethanolic extract of unripe fruits of Citrus unshiu (CU-ext) on type IV allergic reaction was examined by inhibitory activity of ear swelling of picryl chloride-induced contact dermatitis (PC-CD) in mice. Oral administration of CU-ext and subcutaneous administration of prednisolone

This study examined the passive cutaneous anaphylaxis-inhibitory activity of the flavanones isolated from the pericarp of Citrus unshiu (Family Rutaceae) and the fruit of Poncirus trifoliata (Family Rutaceae). Naringenin, hesperetin and ponciretin potently inhibited IgE-induced beta-hexosaminidase

When hesperidin isolated from pericarpium of Citrus unshiu (family Rutaceae) was incubated with human intestinal microflora, its main metabolite was hesperetin, which was a main metabolite in urine of orally hesperidin-administered rats. The antiallergic activity of hesperidin and its metabolite

In a previous study we found that 50% ethanol extracts of immature fruits of Citrus unshiu (satsuma mandarin) have anti-allergic effects against the Type I, II and IV allergic reactions. However, many adverse interactions between citrus fruit, especially grapefruit juice, and drugs have been

Nobiletin and tangeretin are polymethoxy flavonoids that are abundantly present in the pericarp of Citrus unshiu (family Rutaceae) and the fruit of Citrus depressa (family Rutaceae). They exhibit various biological activities, including anti-inflammatory and anti-asthmatic effects. To evaluate the

In April 2015, Consumer Affairs Agency of Japan launched a new food labeling system known as "Foods with Function Claims (FFC)." Under this system, the food industry independently evaluates scientific evidence on foods and describes their functional properties. As of May 23, 2017, 1023 FFC
