This study aimed to investigate the ash content and concentrations of inorganic elements present in the stem of Acacia mangium. The tree samples (24 years) were collected from five different provenances (Sidei, West of Morehead, Daintree, Ellerbeck, and El Arish). Meanwhile, the disc samples were obtained from the trunk of each tree on the lower parts. The samples were collected from four radial positions (bark, sapwood, outer heartwood, inner heartwood), and the ash and insoluble acid contents were determined. Furthermore, the concentration of 5 elements (Ca, Mg, Fe, Mn, K, and Na) was measured by Atomic Absorption Spectrophotometry (AAS). The interaction of provenance and radial position factors affected ash and potassium contents. Also, acid insoluble ash and calcium contents showed a provenance factor effect. The barks obtained from the tree samples contained the highest concentrations of ash content and most of the elements. The wood and bark of El-Arish provenance showed the lowest (0.50~0.72%) and highest levels (4.75%) of ash content respectively. Furthermore, the highest amount of insoluble acid ash (3075 ppm) and calcium (4513 ppm) content was also measured in samples of El-Arish provenance, and radial position factor was a significant source of variation for Ca, Mg, Na, and Mn concentrations. Except Mg, the inner and outer portions of the heartwood mostly showed no significant difference in unprecedented element concentrations. Ash content was positively correlated with Ca in sapwood (r=0.39) and Mn in bark (r=0.54). In addition, moderate correlations were observed between Mg and Ca in heartwood (r=0.63) and bark (r=0.54) tissues. For ash and silica content, the comparatively low concentration on samples from El-Arish provenance are good options to improve wood quality for breeding programs.

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.

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.

Dalbergia latifolia is one of the famous species that naturally grows in Java, Indonesia. The wood of this species is purple in color and the leaf is utilized as forage. The purpose of this study is to determine the bioactivity and phenol contents of D. latifolia leaf ethanolic extract. The antioxidant activity and anti-termite activity were measured through the DPPH method and Neotermes bosei activity. Furthermore, phenol contents were determined through colorimetric method and ethanolic extract constituents were identified by GC-MS. The DPPH inhibition of ethanol extract of D. latifolia leaf exhibited 138.20±2.14 µg/ml. While the measurement of total phenol and total flavonoid content of D. latifolia leaf showed a value of 192.67±9.41 mg GAE/ g and 55.23±5.11 mg QE/ g of dried extract sample. The termiticidal activity of ethanolic extract showed low activity. The GC-MS detection showed fatty acids as dominant compounds. The inhibition of DPPH by D. latifolia leaf ethanol extract in this study suggested this leaf is potent as antioxidant agents.
