Etlingera maingayi (also known as Malay rose)[1] is a species of herbaceous perennial plant[citation needed] of the Zingiberaceae family. This species occurs in southern Thailand, where its flowers are eaten as vegetables, and Malaysia.[2]

Description[edit]

E. maingayi grows to less than 2 m (6 ft 7 in) high.[3] Its leaves are variable, with undulating fringes, and emit a sour scent when crushed.[4] Young leaves are translucent and reddish on both sides.[2]

Chemistry[edit]

Leaves of E. maingayi displayed ferrous ion chelating ability and lipid peroxidation inhibition activity that were much higher than young leaves of Camellia sinensis.[4] Leaves of E. maingayi had the highest yield of oil (1320 mg/100 g) consisting mainly of lauric acid (45%) and decanoic acid (43%). The unpleasant sour scent of leaves when crushed may be due to these two acids.
