A new glycoside from the leaves of Neoalsomitra integrifoliola

A new ionone glycoside (6R,9R)-blumenyl α-l-rhamnopyranosyl-(1 → 6)-β-d-gluco-pyranoside (1), together with a new natural product 2-methoxyl-4-trans-propenyl-phenol α-l-rhamnopyranosyl-(1 → 6)-β-d-glucopyranoside (2), was isolated from the leaves of Neoalsomitra integrifoliola. Their structures were elucidated by chemical and spectral analysis. Compound 1 showed weak anti-inflammatory and low-level antioxidant activities.
