Chemical characterization and antioxidant potential of volatile oil from an edible seaweed Porphyra tenera (Kjellman, 1897)
BACKGROUND Porphyra tenera (Kjellman, 1897) is the most common eatable red seaweed in Asia. In the present study, P. tenera volatile oil (PTVO) was extracted from dried P. tenera sheets that were used as food by the microwave hydrodistillation procedure, after which the characterization of its chemical constituents was done by gas chromatography and mass spectroscopy and its antioxidant potenti...
متن کاملNutritional composition of edible seaweed Gracilaria changgi
Gracilaria changgi, an edible seaweed was analyzed to determine its proximate chemical composition, mineral elements, vitamin C, b-carotene, free fatty acid and amino acid contents. G. changgi showed vitamin A activity of 865 mg rectinol equivalents/100 g sample. It contained a higher composition of unsaturated fatty acids (74%), mainly the omega fatty acids and 26% of saturated fatty acids (ma...
متن کاملThe nucleotide sequences of 5S rRNAs from two red algae, Gracilaria compressa and Porphyra tenera.
The nucleotide sequences of 5S rRNA from two red algae, Gracilaria compressa and Porphyra tenera have been determined. The two 5S rRNAs are fairly dissimilar to each other in their sequences (65% identity), although they are both composed of 121 nucleotides. Their secondary structures are generally of the eukaryotic with a prokaryotic characteristic. Judged from the 5S rRNA sequence data, the r...
متن کاملStudies on the Listerella Group: I. Biochemical and Hemolytic Reactions.
Although the organisms now known as Listerella were first reported as a new species by Murray, Webb and Schwann (1926), and were given the genus name by Pirie (1927), earlier reports contain descriptions which indicate that the organisms were seen prior to 1926. Atkinson (1917) noted a gram-positive diphtheroid organism in five human cases of what was thought to be epidemic cerebrospinal mening...
متن کاملHigh-Resolution Lipidomics of the Early Life Stages of the Red Seaweed Porphyra dioica.
Porphyra dioica is a commercial seaweed consumed all over the world, mostly in the shape of nori sheets used for "sushi" preparation. It is a well-known part of the Asian diet with health benefits, which have been associated, among others, to the high levels of n-3 and n-6 fatty acids in this red alga. However, other highly valued lipids of Porphyra are polar lipids that remain largely undescri...
