Abstract
The genus Ziziphora belongs to the family Lamiaceae and comprises 62 species growing as perennial or annual herbs from South-West Asia to Eastern Europe. In Pakistan this genus is represented by two species. One of these is Ziziphora tenuior which grows in Balochistan and Northern Provinces of Pakistan [1]. It is locally used as herbal tea due to its sweet fragrance. The literature revealed that no phytochemical or pharmacological studies have been carried out on this species so far. The chemotaxonomic and ethnopharmacological importance of the genus Ziziphora prompted us to carry out phytochemical studies on Z. tenuior. As a result, we herein report the isolation and structural elucidation of two new flavonides named as ziziphorin A (1) and ziziphorin B (2) (Fig. 1), along with the known compounds 1-hentetracontanol (3) [2], ursolic acid (4) [3], oleanolic acid (5) [4], β -sitosterol-3-O-β -glucoside (6) [5] (Fig. 2), and apigenin (7) [6].
