Extraction and Identification of Two Secondary Metabolites from Teucrium stocksianum Boiss.

TeucriumstocksianumBoiss belongs to Lamiaceaefamily that havenumerous traditional uses as medicinal plant [1]. Reported activities for the Teucrium genus are anti-inflammatory, antibacterial, antifungal, antioxidant and antispasmodic.Moreover, the importance of the biological activities of the Teucrium species is evident as larvicidal, hypoglycemic, antispasmodic, antinocieceptive, hepatoprotective[2, 3]. Teucriumstocksianum Boiss. Growin gwild in south of Iran, Hormozgan: Hajiabad, Sirmand, Talmara, 800 m, was collected in April 2015 by M. A. Soltanipour. As a part of ongoing research program aimed at the isolation, structural elucidation and pharmacological evaluation of bioactive secondary metabolites from plants, we started the phytochemical analysis of TeucriumstocksianumBoiss. Our studies led to the isolation of two flavonoids(1 and 2 in Figure 1), together with several compounds, whose structures were secured by 1D and 2DNMR spectroscopic studies, in particular homo-COSY and hetero-(HMQC and HMBC).
