| description | Teak (Tectona grandis (L.) Finn.) and acacia (Acacia mangium Willd.) are
important forest crop. These plants contain high secondary metabolites in the
leaves. Phenolics and terpenoids as parts of secondary metabolites have an
allelopathic effects which give negative interaction with another organism as a
defense mechanism. The aim of this work was to assess the changes of phenolics
and terpenoids type and composition in the leaf of different ages. Extraction of
secondary metabolites were made by maceration using khloroform, methanol,
ethanol : water and n-hexane. Phenolics and terpenoids extracts from different leaf
age were analyzed qualitatively by TLC (Thin Layer Chromatography) and
quantitatively by GC � MS ( Gass Chromatography Mass Spectra). Total
phenolics compound (TPC) was measured by spectrophotometry methods using
Folin Ciocalteau reagent. Leaf anatomy on different age were observed under
light microscope, leaf tissue thickness measured by Image Raster Optilab. TLC
were observed under UV 254 nm, 366 nm and using FeCl3, sulfuric acid
anisaldehyde reagents. GC � MS analysis indicated a changes in levels and types
of phenolics and terpenoids components of leaf extracts of different age. Total
phenolics compound in acacia is higher than in teak and change according to the
age of the leaf. Leaf cross section of teak showed the presence of trichomes as a
site of secondary metabolites accumulation. Thickness of mechanical tissues
increases with leaf age. |
