A new flavan‐4‐ol glycoside, abacopterin K ( 1 ), and a new dihydrochalcone glycoside, abacopterin L ( 2 ), were isolated from the rhizomes of Abacopteris penangiana. Their structures were elucidated on the basis of various spectroscopic analyses and chemical evidences. The novel glucosylation pattern of abacopterin K consisting of two ‘glucose‐fused’ dioxepine ring moieties is found for the first time within natural flavonoids.
