POTAMOGETON MALAIANUS MIQ
Phylum: Magnoliophyta
Class: Liliopsida
Order: Alismatales
Family: Potamogetanaceae
Common name: Pond weed
Distribution: China, Central and South America, Central Asia
Habitat: Aquatic habitats, ponds
Description: In this submersed species, the leaves (7 × 2 cm) are member-
anous, light green, and linearly elliptical.
Compounds and activities: The methanol extract of this species has yielded
bioactive compounds such as new furanoid labdone diterpenes, viz., pota-
mogetonyde and potamogetonol, and two known compounds, viz., potamo-
getonin and 15,16-epoxy-12-oxo-8,13,14-labdatrien-20,19-olide. Among
them, the compounds shown below exhibited cytotoxity against the vero
cell line with respective IC 50 values of 31 and 28 µg/ml. These compounds
showed potent antiviral (HSV-1) activity with IC 50 values of 8 and 3 µg/ml
respectively. However, all compounds showed antimalarial activity and
cytotoxicity toward mosquito larvae with IC 50 values ranging from 11 to
72 µg/ml (Kittakoop et al., 2001) .
