Gracilaria lemaneiformis is cultivated on a large scale in China for industrial production of agarose, a natural polysaccharide, which has been shown to have many beneficial bioactivities such as antitumor, antiviral antioxidant activities, etc. In the present study, the hypoglycemic and antioxidant effects of a polysaccharide extracted from Gracilaria lemaneiformis (GLP; Mw, 121.89 kDa) and it...

The economically important seaweed Gracilariopsis lemaneiformis ( Gp. ) is the main resource for agar production and abalone bait. Few studies have focused on functions of glycosyltransferases (GTs) glycoside hydrolases (GHs) involved in saccharometabolism, including that agar. To investigate possible glycosyltransferase family 7 (GT7) hydrolase 16 (GH16) members metabolism, analyses these gene...

gracilariopsis persica (rhodophyta) is one of the most abundant algae, introduced newly from the indian ocean. in this study,   the main sterols of the algae have been isolated and identified. separation and purification of the compounds was carried out on silica gel and sephadex lh20 column chromatography (cc) and high performance liquid chromatography (hplc) to obtain five pure compounds 1-5....

The sulfated polysaccharides (SP) from the edible red seaweed, Gracilaria birdiae, were obtained using five different extraction conditions: Gracilaria birdiae 1 (GB1)-water; GB1s-water/sonication; GB1sp-water/sonication/proteolysis; GB2s-NaOH/sonication; and GB2sp-NaOH/sonication/proteolysis. The yield (g) increased in the following order: GB2sp>GB1sp>GB2s>GB1s>GB1. However, the amount of SP e...

BACKGROUND AND OBJECTIVES Leishmaniasis is a protozoan parasitic disease which is transmitted by the female Phlebotomus sand fly and is prevalent in four continents.The first-choice treatment for the leishmaniasis is pentavalent antimonials, which are potentially toxic and often ineffective and use of them exhibit therapeutic failure. These pharmaceutical problems point towards the need to deve...
