Avrainvillea Explained

Avrainvillea is a genus of green algae in the family Dichotomosiphonaceae.

Description

Avrainvillea is a green siphonous marine macroalgal species.^[1] In the tropical species the dichotomously and branched filaments are generally united.^[2]

Distribution

The genus has a worldwide tropical and tropical distribution.^[1]

Ecology

The species occur from the intertidal to 60m.^[1]

As sources of bioactive natural products

Avrainvillea erecta was reported to have strong hemagglutination activity.^[3] In addition, the chloroform fraction of a methanol extract of Avrainvillea erecta exhibited hydrogen peroxide scavenging activity as strong as that shown by gallic acid.^[4]

Eight new species are listed and described.^[1]
