Blackcurrant name is derived from "Ribes nigrum") and similar fruit syrups and juices. Raw blackcurrants are 82% water, 15% carbohydrates, 1% protein and 0.4% fat (table). Per 100 g serving providing 63 kilocalories, the raw fruit has high vitamin C content (218% of the Daily Value, DV) and moderate levels of iron and manganese (12% DV each). Other nutrients are present in negligible amounts (less than 10% DV, table). Polyphenol phytochemicals present in the fruit, seeds and leaves, are being investigated for their potential biological activities. Major anthocyanins in blackcurrant pomace are delphinidin-3-"O"-glucoside, delphinidin-3-"O"-rutinoside, cyanidin-3-"O"-glucoside, and cyanidin-3-"O"-rutinoside, which are retained in
Idiosoma nigrum Idiosoma nigrum Idiosoma nigrum, also called Black rugose trapdoor spider, occurs only in south-western Australia, in dry woodlands east of the Darling Scarp and north to Moore River. Females can reach a length of about 30mm, males about 18mm. "I. nigrum" digs burrows up to 32 cm deep. The species name is derived from Latin "Niger" "black". The Black Rugose Trapdoor Spider is adapted for life in semi-arid habitats. They live in burrows up to 32 cm deep. These spiders construct an arrangement of leaves and twigs radiating out from the burrow entrance to serve as remote sensing device -
