Abstract
The anthocyanin pigments of red garlic (Allium sativum L.) and red onion (Allium cepa L.) were extracted with 0.01% HCl in methanol and purified by paper chromatography. The purified pigments were identified by chromatographic, spectral and chemical properties of each anthocyanins, anthocyanidins and sugar moieties. Red garlic and red onion anthocyanins were separated 7 or 8 bands by paper chromatography. The anthocyanin pattern of red garlic was very similar to that of red onion. The major pigment of red garlic and red onion was cyanidin 3-glucoside. Cyanidin 3-laminariobioside which recently reported to occur in spanish red onion was found in two varieties of red onion in Japan.
