title: [Chemical constituents of Drynaria propinqua (Wall) J. Sm].
abstract: Four compounds isolated from the rhizomes of Drynaria propinqua collected in Sichuan have been identified. One of them was a new natural product, namely propinqualin, whose structure was established as (-)-epiafzelechin-3-O-beta-D-allopyranoside. The other three were 4-O-beta-D-glucopyranosyl caffeic acid, beta-sitosterol-3-O-beta-D-glucopyranoside and sucrose.
