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 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 کاملEffects of Extraction and Processing Methods on Antioxidant Compound Contents and Radical Scavenging Activities of Laver (Porphyra tenera)
Laver is one of the most consumed edible red algae seaweeds in the genus Porphyra. Laver is primarily prepared in the form of dried, roasted, and seasoned products. We investigated the total polyphenol and flavonoid contents of laver products, and evaluated the in vitro antioxidant properties of solvent extracts from commercially processed laver products. Significant differences in the concentr...
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 کاملHemoglobin Yakina. I. Clinical and biochemical studies.
Three members of a family who have erythrocytosis and a new hemoglobin, designated hemoglobin Yakima, are described. The abnormal hemoglobin is characterized by the substitution of histidine for aspartic acid at residue 99 in the beta-chain. Of three possible structure-function relations which would account for the increased oxygen affinity of hemoglobin Yakima, only two seem likely. These are:...
