Isolated five known iridoids glycosides (Scrophuloside A, Harpagoside B, 5-hydroxyloganin, 8-O-acetylharpagide and 6-O-methyl,1-glucopyranosyl catalpol), one phenyl ethanoid glycoside (Verbascoside) and a phenyl ethanol amine (2-(4-Chlorobenzyl amino) ethanol) compound from the methanolic extract of aerial parts of Scrophularia oxysepala using by high performance liquid chromatographyare based ...

An effective high-speed counter-current chromatography method was established for the preparative isolation and purification of two phenylpropanoid glycosides from the Tibetan medicinal plant Pedicularis longiflora Rudolph. var. tubiformis (Klotz). Tsoong. With a two-phase solvent system composed of chloroform-n-butanol-methanol-water (4:3:4:5, v/v), 40 mg of an extract of Pedicularis longiflor...

Vegetable and natural product utilization are conversely connected with diminished malignant growth rate mortality. Fruit antioxidants have been extensively studied for their ability to scavenge free radicals, preventing develop the chronic degenerative diseases. As antiproliferative agents, mixtures of biophenols were more effective than individual biophenols. The tyrosol hydroxytyrosol major ...

This paper investigates the impact of a polyphenol-enriched supplement comprised hibiscus (Hibiscus sabdariffa) and lemon verbena (Lippia Citriodora) (brand name Metabolaid®) on gut microbiota composition functionality, by performing fermentations with human faecal under gut-simulated conditions. Results indicated that Metabolaid®, in dose-dependent manner, modulated bacteriome to higher relati...

Girdling (a ring of bark approximately 5 mm wide) was applied on olive mother plants to investigate its effect the rooting ability cuttings. Treatment in autumn and spring. The cuttings were then immersed for s into 2000 mg L?1 indole-3-butyric acid (IBA) a 45% v/v ethanolic solution. Thirty days after girdling, taken from girdled control shoots part just above girdle zone (basal), as well righ...

BACKGROUND Most researches were focused on chemical constituents and bioactivities of Pedicularis. However, there were a few reports on simultaneous determination of the series phenylpropanoids compounds in Pedicularis by High Performance Liquid Chromatography (HPLC). OBJECTIVE To establish an HPLC method for simultaneous determination of salidroside, verbascoside, iso-verbascoside, leucosept...
