title: Bacopaside III, bacopasaponin G, and bacopasides A, B, and C from Bacopa monniera.
abstract: Two new saponins, 3-O-[6-O-sulfonyl-beta-d-glucopyranosyl-(1-->3)]-alpha-l-arabinopyranosyl pseudojujubogenin (1) and 3-O-[alpha-l-arabinofuranosyl-(1-->2)]-alpha-l-arabinopyranosyl jujubogenin (2), a new matsutaka alcohol derivative, (3R)-1-octan-3-yl-(6-O-sulfonyl)-beta-d-glucopyranoside (3), a new phenylethanoid glycoside, 3,4-dihydroxyphenylethyl alcohol (2-O-feruloyl)-beta-d-glucopyranoside (4), and a new glycoside, phenylethyl alcohol [5-O-p-hydroxybenzoyl-beta-d-apiofuranosyl-(1-->2)]-beta-d-glucopyranoside (5), were isolated from Bacopa monniera. Their structures were established by NMR, MS, and chemical methods.
