Alcoholic extracts of 8 different types of seaweeds from Iran's Persian Gulf were tested for their antimalarial and acetylcholinesterase enzyme (AChE) inhibitory activities for the first time. A modified Ellman and Ingkaninan method was used for measuring AChE inhibitory activity in which galanthamine was used as the reference. The antimalarial assay was performed using microculture radioisotop...

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. S...

Gracilariopsis lemaneiformis has a high economic value and is one of the most important aquaculture species in China. Despite it is economic importance, it has remained largely unstudied at the genomic level. In this study, we conducted a genome survey of Gp. lemaneiformis using next-generation sequencing (NGS) technologies. In total, 18.70 Gb of high-quality sequence data with an estimated gen...

agar is a gelling biopolymer that can be extracted from cell wall of some red algae. in this present, response surface methodology was used to investigate the procedure of agar melting point and gelling temperature from cultural algae of gracilariopsis persica. independent variables, alkalinity concentration (2, 3.2, 5, 6.8, -8%), extraction temperature (90, 96, 105, 114, 120°c) and extraction ...

Oliveira, V. P.; Freire, F. A. M. & Soriano, E. M. 2012. Influence of depth on the growth of the seaweed Gracilaria birdiae (Rhodophyta) in a shrimp pond. Braz. J. Aquat. Sci. Technol. 16(X): 33-39. eISSN 1983-9057. This study evaluates the influence of depth and environmental parameters on the development of Gracilaria birdiae Plastino & Oliveira (Gracilariaceae) in an organic shrimp pond. The...

OBJECTIVE In vitro antioxidant activities of three selected Indian seaweeds viz., Halimeda tuna (H. tuna), Turbinaria conoides (T. conoides) and Gracilaria foliifera (G. foliifera) were evaluated. METHODS Total antioxidant activity, total phenolic content, and reducing power of crude methanol and diethyl ether extracts were determined. RESULTS Total phenolic content and total antioxidant ac...

Makroalga telah digunakan industri pangan sejak lama karena komponen yang dikandungnya misalnya alginat, karagenan, dan agar. Selain itu alga mengandung nutrisi bioaktif lainnya sebagai fungsional. Kandungan protein keragaman jenis asam amino dapat menjadi informasi penting untuk memaksimalkan potensi dimiliki alga. Penelitian ini bertujuan mengetahui kandungan profil pada S.aquifolium, U. lact...
