KARAKTERISASI SENYAWA ISOPRENOID DAN PERTUMBUHAN SEMAI MANGROVE AVICENNIA ALBA BL.
ABSTRACT: This study aims to
determine the characterization of isoprenoid compounds in the mangrove A. alba
and seedling growth of A. alba at different levels of salinity. The results
showed the total lipids in the leaves of A. alba (21 mg) was higher than that
in the roots (11,7 mg). Total Non Saponifiable Lipids (NSL) content in the
leaves of A. alba (1,1 mg) greater than that in the roots (0,6 mg). NSL
composition of A. alba consists of 3 major factions namely triterpenoids,
phytosterols, and other compounds. Phytosterol composition in the leaves and
roots of A. alba showed the presence of compounds such as campesterol,
stigmasterol and β-sitosterol. As frase for the composition triterpenoid found
the presence of β-amyrin, germanicol, betulin, lupeol and α-amyrin. Phytol,
cholesterol, and squalene were also found as the other compounds. The content
of the NSL triterpenoid was higher than phytosterol in the leaves and roots of
A. alba. The results also showed that phytol compounds had the highest content
of leaves of A. alba (71.4 %) and the β-sitosterol had the highest content of
root A. alba (27.8 %). Based on the analysis of the effect of salinity on
seedling growth of A. alba showed that the salinity of 2% significantly
affected the seedling height and diameter of 3 months of A. alba.
