Asterosaponins isolated from the starfish Asterias amurensis.
Three new asterosaponins 1-3 and four known saponins 4-7 have been isolated from the starfish Asterias amurensis LÜTKEN. By means of high magnetic field 1D- and 2D-NMR ((1)H-(1)H correlation spectroscopy (COSY), total correlation spectroscopy (TOCSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear single quantum coherence (HSQC), heteronuclear multiple bond correlation (HMBC), a...
متن کاملThe Restoration Method for Recognition of Asterias Amurensis
This paper aims to recognize and extract deformed Asterias amurensis through the use of the concave and convex feature points, central moment, and short lines and long lines. Another purpose of this paper is to restore Asterias amurensis using the radial symmetry. Marked by the characteristics that include pentaradiality and the ability to vary in outward shapes according to circumstances, Aste...
متن کاملThe Restoration Technique for Recognition of Asterias Amurensis
Asterias amurensis, also referred to as the Northern Pacific seastar, is so indiscriminate a predator that it deserves to be called pirates of the sea. They usually eat fish and shellfish including abalones and clams. Due to the high fertility rate, Asterias amurensis is one of the main culprits in devastating fishing grounds. Starfish are anywhere in the East Sea and South Sea. In recent years...

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
Isolation and characteristics of carboxypeptidase B from the pyloric ceca of the starfish Asterias amurensis.
Carboxypeptidase B was purified from the pyloric ceca of the starfish Asterias amurensis. The final enzyme preparation was nearly homogeneous in polyacrylamide gel electrophoresis and its molecular weight was estimated as approximately 34,000. The optimum pH and temperature of the enzyme for hydrolysis of benzoyl-glycyl-L-arginine were at approximately pH 7.5 and 55 degrees C, respectively. The...
