Carum petroselinum = Petroselinum crispum = persilja

Apiin, the glucoside of apigenin, is found in the leaves, stem, and seeds of parsley (Carum (Apium) petroselinum, Benth. and Hook.), (Rump, Buchner's Repert. f. Pharm., 1836, 6, 6; Braconnot, Ann. Chim. Phys., 1843, iii., 9, 250). [---]

Apigenin closely resembles chrysin in its tinctorial properties, although it is a somewhat stronger dyestuff. The shades it gives upon wool mordanted with aluminium, chromium, and iron are respectively pure yellow, weak yellow-orange, and chocolate-brown.

Apigenin is also present in weld (Reseda luteola), (Perkin and Horsfall, Chem. Soc. Trans., 1900, 77, 1314), in the flowers of Antirrhinum majus (Wheldale and Bassett, Biochem. Jour., 1913, 7, 441), and exists probably also in chamomile flowers (Perkin).
