4. Conclusion
Mangrove plant
Avicennia marina
is a promising source of natural product. From the present study, preliminary phytochemical analysis concluded that due to the presence of extra
phytochemical in test extracts, they are beneficial one for its biological activity. The observed antibacterial activities of the crude extract and the isolated compounds betulinic acid could
justify the traditional use of the plant for the treatment of different bacterial infections. Thus, further test is recommended on large number of bacterial strains to decide their potential as
candidates in development of antibacterial drugs.

Abstract A flavonoid compound, namely matteucinol 5,7-dihydroxy-
4’-methoxy-6,8-dimethyl flavanone had been isolated from the stem of the fern
Chingia sakayensis.
It was separated by chromatographic techniques, purified by recrystalization and obtained as pale yellow powder with melting point of 171-
172
o
C. Its molecular structure was elucidated on the basis of spectroscopic evidences, including UV, IR,
1
H-NMR,
13
C-NMR, 2D-NMR, and EIMS as well as by comparation with those reported data in literature.
Keywords: Fern,
Chingia sakayensis
, flavonoid, matteucinol
