During the course of our studies on physic logically active substances in citrus fruit peelings, three terpenoids and five terpenoid glycosides wereisolated from unshiu and young unshiu peelings. The structures were established by MS, 1H-NMR and 13C-NMR spectroscopy, and chemical evidence: (1 S, 4 R, 6 R)-1, 3, 3-trimethyl-2-oxabicyclo [2. 2. 2] octan-6-ol [1], 6-hydroxy-3-oxo-α-ionone [2], abscisic acid [3], trans-carveol 6-β-D-glucopyranosidt [4], (2 E, 6 R)-2, 6-dimethyl-2, 7-octadien-6-ol-1-O-Β-D-glucopyranoside [5], vomifoliol 9-O-β-glucopy ranoside [6], (6 R, 7 E, 9 R)-9-hydroxymegastigma-4, 7-dien-3-one-9-O-β-D-glucoside [7] and (1 S, 4 R, 6 S)-1, 3, 3-trimethyl-2-oxabicyclo [2. 2. 2] octan-6-O-β-glucopyranoside [8]. Among these compounds, [8] is, a new terpenoid glycoside, whereas [1]_??_[7] were found in unshiu and young unshiu peelings for the first time.
