Oleanane saponins in "kancolla", a sweet variety of Chenopodium quinoa.
Seven triterpenoid saponins were isolated from the seeds of "kancolla", a sweet variety of Chenopodium quinoa. Their structures were phytolaccagenic acid 3-O-[alpha-L-arabinopyranosyl-(1' '-->3')-beta-D-glucuronopyranosyl]-28-O-beta-D-glucopyranoside, oleanolic acid 3-O-[beta-D-glucopyranosyl-(1''-->3')-alpha-L-arabinopyranosyl]-28-O-beta-D-glucopyranoside, hederagenin 3-O-[beta-D-glucopyranosyl-(1''-->3')-alpha-L-arabinopyranosyl]-28-O-beta-D-glucopyranoside, phytolaccagenic acid 3-O-[beta-D-glucopyranosyl-(1''-->3')-alpha-L-arabinopyranosyl]-28-O-beta-D-glucopyranoside, oleanolic acid 3-O-[beta-D-glucuronopyranosyl]-28-O-beta-D-glucopyranoside, oleanolic acid 3-O-[alpha-L-arabinopyranosyl-(1''-->3')-beta-D-glucuronopyranosyl]-28-O-beta-D-glucopyranoside, and the new compound serjanic acid 3-O-[beta-D-glucopyranosyl-(1''-->3')-alpha-L-arabinopyranosyl]-28-O-beta-D-glucopyranoside (1). The structure of 1 was characterized on the basis of spectroscopic and chemical evidence.
