Periplocain A ( 2 ), a new naphthalene derivative together with four known compounds: 2‐ethylhexyl benzoate ( 1 ), quercetin‐3‐ O ‐ α ‐ l ‐rhamnopyranoside ( 3 ), quercetin‐3‐ O ‐ β ‐ d ‐glucopyranoside ( 4 ), and quercetin‐3‐(6‐ O ‐ α ‐ l ‐rhamnopyranosyl‐ β ‐ d ‐glucopyranoside) ( 5 ) were isolated from the AcOEt fraction of the aerial parts of Periploca aphylla (Asclepiadaceae). Their structures were established by multiple spectroscopic methods in addition to HR‐ESI‐MS and by comparison with literature data.
