Abstract
Avicennia lanata is commonly known as grey mangroves or white mangroves which
classified in the family of A vicenniaceae. Several researches were conducted on its
closely related species Avicennia marina but there is no or few being carried out on A.
lanata. The leaf, bark and root part of this plant has been extracted sequentially using
dichloromethane, ethyl acetate and methanol respectively. Each of the extracts is
tested for its anti-cholinergic and antimicrobial properties. Two major active
compounds (phenols/tannins and saponins) were observed in the root extracts which
also contained glycosides and freeze dried leaf extract with alkaloid compounds. The
highest anticholinesterase (AchE) enzyme activity is showed by freeze dried leaf
extract with 86.22% of AchE enzyme inhibition then followed with 73.37% and
71.73% from methanol root extract and ethyl acetate root extract respectively at
concentration of 2.5µg/ml.
