The greater Equisetum arvense is an herbaceous plant from the family Equisetaceae commonly found in North America, Europe and Asia. has been used since ancient times medical practice because of its pharmacological applications, presence many biologically active compounds, including flavonoids, alkaloids, carbohydrate, proteins amino acids, phytosterols, saponins sterols. Scientific data reveals...

Stelleropsis genus belongs to Thymelaeaceae and has two species in Iran of which S. iranica Pobed. subsp. Iranica Bonge (aerial parts) were collected from the North-East of Iran and extracted with AcOEt and MeOH, consequently. The main phenolic compounds were isolated by different chromatography methods and the structures identified by spectroscopic methods (1H-NMR, 13C-NMR, HMBC, HMQC, H-H COS...

A new flavonoid, acacetin-7-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucuronopyranoside (1), together with four known flavonoids, apigenin-7-O-β-D-glucopyranosyl-(1 (2), acacetin (3), acacetin-7-O-β-D-glucuronide (4) and genkwanin-5-O-primveroside (5) were isolated from the leaves of Glyphaea brevis. Their structures elucidated by spectroscopic techniques. The compounds (1 - 5) tested for their antiox...

Abstract The present study introduces a systematic approach using analytical quality by design (AQbD) methodology for the development of qualified liquid chromatographic method, which is challenge in herbal medicinal products due to intrinsic complex components botanical sources. ultra-high-performance chromatography-photodiode array-mass spectrometry (UHPLC-PDA-MS) technique 11 flavonoids Genk...

Within the secondary metabolite class of flavonoids, which consist of more than 10,000 known structures, flavones define one of the largest subgroups. The diverse function of flavones in plants as well as their various roles in the interaction with other organisms offers many potential applications including in human nutrition and pharmacology. We used two genes, flavone synthase (PFNS-1) that ...
