Abstract

Agarwood is one of non-timber forest product comodites (NTFPs) which has high economic value and as an export commodity. Agarwood produce an aromatic resin substance in the form of lumps that located between the wood cells in various shapes and colors. According to Indonesian National Standards, the category of agarwood is classified into several levels such as agarwood sapwood, kemedangan, and agarwood powder. The classification system is based on color, weight, and aroma. This classification method shows that the current quality of agarwood welding systems is still subjective. Therefore, more objective welding system is needed which is related to the chemical composition and resin content. This study objective is to identify the chemical components of agarwood sapwood from the results of fungal inoculation in agarwood-producing plants of gyrinops versteegii. The research conducted by extracting agarwood sapwood sample using acetone. This agarwood sapwood sample collected from the result of Fusarium, Rhizopus and Trichoderma fungi inoculation for 1 year. Furthermore, the agarwood acetone extract fractionated with a gradient column chromatography with hexane-ethyl acetate eluent. The method to identify the compounds/component is using chromatography gas-spectro-photometer mass (GC-MS). The results showed that the chemical components contained in agarwood from fungal inoculation were mostly in the form of ester compounds. The highest types compounds and the highest density compound were found in agarwood produced by Trichoderma fungi inoculant, namely Hexanedioic acid, dioctyl ester; 11-octadecanoic acid, methyl ester; Cyclopropanedodecanoic acid, 2-octyl-, methyl ester; 9-octadecanoic acid, methyl ester; Octadecanoic acid, 9.10- dihydroxy-, methyl ester; Cyclopropanepentanoic acid, 2-undecyl-, methyl ester; Pentadecanoic acid, 14-methyl-, methyl ester; and non-ester compounds, namely: 2-tridecenI-ol; 2- (2 ’, 4’, 4 ’, 6’, 6 ’, 8’, 8’Heptamethyltetrasiloxan -2 ’; 3-Hydroxybutanamide. 8- methoxy-2- (2.

Highlights

Agarwood sapwood is a solid lump product with brownish-black color or black color that has a nice fragrance and produced on the wood or roots of the host tree
MATERIALS AND METHODS Material in the form of agarwood from 4 treatments, namely: A, B, C, and D
The sapwood samples were produced by agarwood-producing trees (Gyrinops versteegii) that had been inoculated for 1 year (12 months) in farmland at Marga Dauhpuri Village, Marga District, Tabanan Regency

Summary

Introduction

Agarwood sapwood is a solid lump product with brownish-black color or black color that has a nice fragrance and produced on the wood or roots of the host tree (for example Aquilaria sp.). The wood part underwent a process of physical and chemical changes due to the infection of fungi (Faizal and Esyanti, 2018). Agarwood is one of the non-timber forest product commodities (NTFPs) that has high economic value, as an export. IDENTIFICATION OF AGARWOOD SAPWOOD CHEMICAL COMPONENTS FROM FUNGAL INOCULATION RESULTS ON Gyrinops versteegii (Gilg.) DOMKE PLANTS I M. The government has declared agarwood as a national non-timber forest product commodity that needs to be developed on a broader scale (Santosa, 2009). The great number of agarwood sapwood demands abroad because of the benefits of agarwood such as perfume, cosmetics, medicines, and religious ritual purposes (Akter et al, 2013)
