Abstract

The investigation on the n-hexane lipophilic extractives of Swietenia mahagoni, alongside the antifungal and antioxidant properties was conducted. The leaf sample was collected from 2- and 3-years-old trees in Perhutani enterprise of Temanggung, Central Java, Indonesia. In addition, the antifungal activity was tested using the white-rot of Phanerochaete chrysosporium, while the antioxidant property involved the DPPH (1,1-diphenyl-2-picrylhydrazyl) method. The results show antifungal of 28.6% and 37.5% growth inhibition in 2- and 3 -years-old leaf, respectively, while 21.7% and 25.4% antioxidant activity were also recorded. Furthermore, the GC-MS results showed the domination of S. mahagoni leaf by fatty acids and hydo-carbons, while the terpenoids and steroids were in minor quantities. These components possibly exhibit growth inhibitory and antioxidant effects against P. chrysosporium and DPPH radicals, respectively.

Abstract

Dalbergia latifolia wood is a beautiful wood with color of dark purple to dark brown and rich in flavonoid compounds. This study aimed to investigate the presence of flavonoid compounds from D. latifolia wood and their contribution to its color. The D. latifolia wood sample was powdered and extracted with ethanol-toluene (1/2, v/v). The ethanol- toluene extract then was column chromatographed to obtain fraction 1 to fraction 12. Methylation was conducted to each fraction to detect flavonoid compounds by GC-MS. The results of GC-MS analysis showed that ethanol- toluene extract gave Fr- 1- Fr. 3 as soluble flavonoids (34.2%) and Fr. 4- Fr. 12 as insoluble polymers (62.6%). Furthermore, 12 flavonoids i.e latifolin, dalbergiphenol, chalcone, dalbergin, and their derivatives were characterised and these compounds might be significance in contributing to color of D. latifolia wood.
