Three new neo-clerodane diterpenoids, one C-16 epimeric pair, scutegalerins C and D, and scutegalerin E, together with the known scutaltisin B, were isolated from the acetone extractof the aerial parts of Scutellaria galericulata. The chemical structures of the new compounds were elucidated by spectroscopic techniques and a comparison with data of similar compounds as (13S,16R,19S)-6a-acetoxy-2...
Sex discriminating genetic markers are commonly used to facilitate breeding programs in economically and ecologically important animal and plant species. However, despite their considerable economic and ecological value, the development of sex markers for kelp species has been very limited. In this study, we used the recently described sequence of the sex determining region (SDR) of the brown a...
A rapid method of microwave-assisted extraction coupled with high-speed counter current chromatography and UV detector was established for the preparation of phytosterols from edible marine algae. Extraction conditions, namely microwave power, liquid/solid ratio, irradiation time and extraction temperature were optimized using orthogonal array design. The microwave-assisted extraction of Undari...
American skullcap (the aerial part of Scutellaria lateriflora L.) has been traditionally used by Native Americans and Europeans as a nerve tonic, sedative, and anticonvulsant. However, despite some previous studies, the quality and safety, the bioactive ingredients, and the pharmacological properties of American skullcap are not fully understood. The aims of this study were to characterize the ...
مقدمه: داروهای سیتوتوکسیک عواملی هستند که به طور مستقیم سلول را نابود می‌نمایند به طوری که بر مراحل مختلف سنتز و فعالیت اسیدهای نوکلئیک اثر می‌گذارند و تقسیم سلولی را مهار می‌کنند. بررسی اثرات سیتوتوکسیک عصاره‌های خام گیاهی به روش‌های in vitro هزینه کمتری داشته، حساسیت بیشتری دارا بوده و آزمایش در زمان کوتاه قابل انجام است از طرفی مقدار نمونه موردنیاز برای آزمایش نیز کمتر است. هدف: در این مط...
