Abstract

Two new steroids provisionally named as pakisteroid‐A (1) and pakisteroid‐B (2) have been isolated in crystalline form from Abutilon pakistanicum. Their structures have been assigned as 3‐O‐β‐D‐glucopyranosyl‐stigmasta‐5,11(12)‐diene (1) and 24β‐ethylcholesta‐5, 9(11), 22E‐trien‐3β‐benzoate (2), respectively through extensive NMR studies.
