A Review on Halodule uninervis – A Potent Seagrass

Halodule uninervisis a βlowering plant commonly known as needle seagrass. Halodule uninervis is widely distributed in the Indo-paciβic region. In the Indian Ocean, it is found from Geographe Bay in Western Australia. It is a eury-
haline species that can tolerate high salinity, grows, reproduce and complete their entire life cycle undersea at the submerged condition. Halodule unin- erviswas found to be rich in phenol and phenylpropanoid derivatives such as
p-coumaric acid, caffeic acid, p-hydroxybenzoic acid and vanillic acids. As the seagrasses are known to produce unique secondary metabolites as a defense mechanism, many research was targeted towards them in order to search novel potent antioxidants or antibiotics. p-hydroxybenzoic acid acts as an intermediate for several bioproducts that are commercially valuable in food, cosmetics, pharmacy, fungicides, etc. Caffeic acid acts as a free radical scav-
enger. It has been found that caffeic acid phenyl ester inhibits DNA, RNA and protein synthesis in HL-60 cells; thus, it arrests the growth of human
leukaemia cells. The western Paciβic and Indian oceans are the indigenous origins of Halodule uninervis. Interesting the fact that Halodule uninervisis an important food for the green sea turtle and dugong and as well as it was used
traditionally for wound ailments. These make the seagrass Halodule uninervis a potent plant that needs to be exposed. This review elaborates on the features and recent approaches of the seagrass Halodule uninervis.
