Microphynolides A and B, new spiro-γ-lactone glycosides from <i>Thymelaea microphylla</i>

<div><p>Two new spiro-γ-lactone glycosides named microphynolide A (<b>1</b>) and microphynolide B (<b>2</b>), together with twelve known compounds including five biflavonoids namely neochamaejasmin A, neochamaejasmin B, daphnodorin B, genkwanol A and stelleranol, one bis-coumarin daphnoretin, two lignans called pinoresinol and matairesinol, one flavonoid glucoside, tiliroside, a sinapyl alcohol glucoside, syringin, and two phytosterols, β-sitosterol and β-sitosterol-3-<i>O</i>-glucoside, were isolated from ethyl acetate extracts of the aerial parts and roots of the plant <i>Thymelaea microphylla</i> Coss. and Dur. All the isolated compounds were characterised by using spectroscopic methods and comparison with the literature data.</p></div>
