Morphology

Fronds
Pinnate, rigid, coriaceous, glabrous, 0.9–1.8m long and 30cm wide, with a rigid naked strip 30–60cm long. The pinnae oblong-lanceolate, the lower shortly stalked and barren, 15–35cm long and 2.5–5.0cm wide; the upper fertile, almost sessile, one 10–15cm long, 1.5–2.5 cm broad, with a recurved margin all rounded and obtuse, or mucronat at the apex, rounded or shortly cuneate at the base and with the margin entire. The mid-rib conspicuous; veinlets often obtuse, anastomosing freely into small irregular areolae, but without any main veins, or any free veinlets. The fertile pinnae wholly occupied with sori except the mid-rib.

Chemical compound
Ethanol extract of A. aureum has been reported to contain reducing sugars, alkaloids, glycosides, saponins, tannins, steroids, flavonoids, gums and terpenoids. Methanol extract on the leaf parts of A. aureum contains patriscabratine, (2-acetamido-3-phenylpropyl) 2- benzamido-3-phenylpropanoate, (2R,3S)-sulfated pterosin C and tetracosane.
