هیپرکلسترولمی یکی از عوامل خطر در ایجاد بیماری های قلبی و عروقی است. یک روش درمانی مورد استفاده برای هیپرکلسترولمی، مهار سنتز کلسترول، بوسیله مهارکننده های آنزیم 3-هیدروکسی-3-متیل گلوتاریل کوآنزیم آ ردوکتاز است. داروهای مورد استفاده برای کنترل بیماری، عوارض جانبی نشان می دهند. بنابراین، با درنظر داشتن این هدف، تأثیر عصاره متانولی شانزده گیاهان بر روی آنزیم 3-هیدروکسی-3-متیل گلوتاریل کوآنزیم...
Hypericum is a genus of flowering plants and presents nearly worldwide distribution. The relevance its species mainly based on the occurrence specialised secondary metabolites exhibiting wide range pharmaceutical cosmeceutical properties. most well-reported in last decade H. perforatum, together with exceptional polycyclic polyprenylated acylphloroglucinols metabolites. Several inhibitory enzym...
in the present study, the tangrah region located in the vicinity of golestannational park was selected for exploring the changes in the amount of the secondaryessential of hypericin in hypericum perforatum in different highlands of the easterngolestan province. the aerial flowered parts of the herb were collected randomly and inthree replications from four altitudes of 300 m, 600 m, 900 m, and ...
Corolla chirality, the pinwheel arrangement of petals within a flower, is found throughout the core eudicots. In 15 families, different chiral type flowers (i.e., right or left rotated corolla) exist on the same plant, and this condition is referred to as unfixed/enantiomorphic corolla chirality. There are no investigations on the significance of unfixed floral chirality on directed pollen move...
Antimicrobial and cytotoxic constituents from native Cameroonian medicinal plant Hypericum riparium.
Bioassay guided fractionation of Hypericum riparium leaves extract has resulted in the isolation and characterization of three new compounds namely chipericumin E (1), hyperenone C (3), and hyperixanthone (5), together with twenty known compounds. Their structures were elucidated based on comprehensive interpretation of spectroscopic and spectrometric data. Compounds 1-4, and 6-8 displayed mode...
