Abstract

The outer part of a tree, known as the bark, protects the internal tissues from external conditions and attacks from microorganisms. Its antifungal activities are due to the presence of chemicals in this bark. This study aimed at evaluating the toxicity of triterpenoids and steroids from the bark of Pinus merkusii against Phanerochaete chrysosporium (white-rot). The triterpenoids and steroids were isolated from n-hexane extract of the bark through column chromatography. Then, the antifungal activity was evaluated by measuring the growth rate of the fungus on potato dextrose agar (PDA) medium in a Petri dish. The isolation resulted in three triterpenoids (3β- methoxyserratt-14-en-21-one, serrate-14-en-3β,21β –diol, 3α,21β- dimethoxy-D14-serratene) and two steroids (β-sitosterol, Stigmast-4-en-3-one). There was more of antifungal activity with β-sitosterol and serrate-14-en-3β,21β –diol, due to presence of hydroxyl bond and their hydrophobicity.

Abstract

The bark of Swietenia machrophylla is colored dark red, and it is correlated with the extractives constituents such as phenolic compounds. This study, therefore, aims to investigate extractives from the inner and outer bark of S. machrophylla and their effects to color properties. The results showed that the extractive content in the inner bark was higher than the outer except for hot water solubles. In addition, the polyphenols and sugar levels from inner to outer bark were increased, except in the soluble-sugar of hot water extractive. The highest correlation between the absorbance of methanol, hot water-soluble extracts, and total polyphenols were observed using the visual spectrophotometer. The extractives that contributed to the bark's color were indicated from flavonoids with a precursor such as monophenol of catechol and resorcinol.

Abstract

Dalbergia latifolia or sonokeling is a native species of Java, Indonesia, used as an important wood for furniture and building materials, due to the high of durability and beautiful color. This study, therefore, aim to investigate the phenol composition, represented by total phenolic,  flavonoid, and flavanol content, as well as antioxidant activity, conducted by DPPH (1, 1-diphenyl-2-picrylhydrazyl) method on Dalbergia latifolia wood. The sample was extracted using ethanol-toluene solvent in a Soxhlet apparatus, and subsequently subjected to column chromatography. This treatment yielded 12 fractions, which were then evaluated for phenol contents and antioxidant activity. The results showed a high antioxidant activity and total phenolic content in Fr.1- Fr.3, while latifolin was detected and characterized by GC-MS and a literature comparison. Therefore, it was established that the antioxidant activity of D. latifolia wood extractives properly correlated with the total phenolic, but not with the total flavonoid and flavanol contents.
