5 Antiviral Compounds
The antiviral compounds are responsible for producing protective or therapeutic
effects to clear a detectable advantage of the virus-infected host. The use of aquatic
plants traditionally as antiviral components is certainly broader than their applica-
tions in modern drugs. The antiviral compounds isolated from the aquatic plants
include alkaloids, lavol, lavonone, isolavonone, etc.
ANKISTRODESMUS CONVOLUTUS CORDA, 1838
Phylum: Chlorophyta Class: Chlorophyceae
Order: Sphaeropleales Family: Selenastraceae
Distribution: Central Asia, Australia, New Zealand
Habitat: Ponds, lakes, rivers
Description: This species has solitary or groups of two to ive cells (5 µm
diameter, 25 µm long) that are sigmoid, twisted, or fusiform in shape. The
apices of cells are sharply pointed, invariably twisted in opposite directions.
Compounds and activities: The methanol extracts of this species containing
antiviral ACF 1 a and b have been found to be active against Epstein-Barr
virus (EBV). This extract displayed low cytotoxicity and a potent effect in
reducing cell-free EBV DNA (EC 50 < 0.01 µg/ml) with a high therapeutic
index (>28,000) (Kok et al., 2011).
