Mallotus roxburghianus is used in the traditional medicine in North‐Eastern India, but previously no work has been done on the identification of bioactive compounds. Two new compounds, 3‐(1‐ C ‐ β ‐ D ‐glucopyranosyl)‐2,6‐dihydroxy‐5‐methoxybenzoic acid ( 6 ) and 2,4,8,9,10‐pentahydroxy‐3,7‐dimethoxyanthracene‐6‐O‐ β ‐ D ‐rhamnopyranoside ( 7 ) together with β ‐sitosterol ( 1 ), stigmasterol ( 2 ), betulinic acid ( 3 ), 4‐hydroxybenzoic acid ( 4 ), β ‐sitosterol‐ β ‐ D ‐glucoside ( 5 ), and bergenin ( 8 ) were isolated and identified from the leaves of M. roxburghianus. The chloroform soluble portion of the alcoholic extract of leaf, and compounds 3, 6, 7 , and 8 exhibited encouraging antioxidant activities.
