“…This triterpenic compound from the lupane series was not found in fresh Shorea resins and is considered as a biomarker characteristic for the distinction between Dipterocarpaceae genera. It appears to be unexpectedly resistant to alteration processes, since it has been detected in some archaeological dammars studied in the laboratory, notably in samples 2307 and 2308 from the terrestrial excavations in Khao Sam Kaeo (4th-2nd c. BC), Thailand (Burger 2008;Burger et al 2009). The resistance of betulonal in the Brunei samples could probably be due to the specific context of preservation: anaerobic contexts are very favourable for the conservation of organic matter.…”

“…1873 and 1874). This particular pattern is characteristic for dammar and allows consequently the discrimination between dammars and other triterpenic resins (Burger 2008;Burger et al 2009), especially mastic (Pistacia genus, Anacardiaceae family) where they are absent (Charrié-Duhaut, pers. comm.…”

“…Triterpenic-derived compounds, not detected in fresh resins, have been characterised in most apolar fractions of archaeological dammars analysed in our laboratory (Burger 2008;Burger et al 2009). We identified them as degradation compounds stemming from the pentacyclic triterpenoids oxygenated in position 3, mainly produced by higher plants (Das and Mahato 1983;Mahato and Sen 1997;Pant and Rastogi 1979).…”

Plant and particularly non-wood forest products have played an important role in the evolution of human cultures all over the world, as source of food but also of raw substances fulfilling material, spiritual, and medicinal requirements. Plant exudates and particularly dammar resins (Dipterocarpaceae family) were widely used in the past in Asia notably as waterproofing and caulking materials. This study focuses on the GC-MS chemical characterisation of freshly collected dammars and establishes new molecular parameters enabling discrimination between dammars and other types of plant resin, whatever their botanical origin. Such analyses provide clues for a precise identification (taxonomy, occurrence of other material in addition to the resin, alteration state) of unknown resinous material discovered in archaeological contexts. The value of our approach is illustrated by the taxonomic characterisation of two samples collected in jars from the Brunei wreck and a Chinese junk lost more than 40 km off the Sultanate of Brunei during the end of the fifteenth century or the early beginning of the sixteenth century.

“…For such an analysis, a solvent extraction followed by derivatization and GC-MS is the most often used technique for the characterization and identification of a wide variety of organic compounds in very small quantities. [15][16][17][18][19][20] HPLC technique is used to characterize olibanum resin or resinous material in general [21][22][23][24][25] but gas chromatography is preferred to analyze archaeological samples, because the use of a such technique is interesting for the analysis of samples available only in small amounts. Indeed, it is very difficult to identify these triterpenic compounds by their single UV spectrum, because these molecules showed very similar maximal absorption wavelengths.…”

& A chromatographic method using fluorescing derivatization was developed for the analysis of triterpenoids in natural resins. The separation was performed using a Luna-C 18 column, an acetonitrile-water eluant mixture, a flow-rate of 1 mL Á min À1 . The fluorescent compounds were detected at 530 nm (excitation at 347 nm). A derivatization reaction of hydroxyl groups of triterpenoids using dansyl chloride is described; this process appeared unusual and provided some novelty. The detection limits were obtained in the range of 0.15-0.45 ng=mL (S=N ¼ 3) for dansylated standard compounds. The described procedure allowed the simultaneous determination of twelve triterpenoids present in frankincense species (Boswellia carteri and B. frereana) and was successfully applied to an archaeological sample coming from an Egyptian mummy. Two other resinous materials, dammar and mastic resins employed in Cultural Heritage, were also studied, in which nine and seven triterpenoids are respectively characterized.

“…It also requires very small sample sizes, which is particularly important for museum and archaeological sampling. GC-MS is the main tool used for chemically characterising archaeological resins in art and archaeology with the subsequent comparison of the molecular compositions with fresh modern resins for genus or species identification [27][28][29][30].…”

Background: Six ethnographic museum resins with documented adhesive, medicinal and narcotic uses have been analysed by gas chromatography-mass spectrometry (GC-MS) as a step towards understanding the role of specific resins in 20 th century Australia and New Guinea. Curated in the Pitt Rivers Museum for over a hundred years, these specimens are examples of resin used for three different purposes, some accompanied by ethnographic accounts from the collectors themselves. Results: The six ethnographic resins have been chemically characterised and identified to species where possible: an adhesive resin from New South Wales is identified as Xanthorrhoea resinosa Pers.; adhesives from New Guinea are tentatively identified as Canarium luzonicum Miq. and beeswax mixed with Canarium spp.; a narcotic resin from New Guinea is identified as Canarium salomonense B.L.Burtt; and the characterisation of spinifex resin from West Australian 'medicine shells' hypothesised to be Triodia irritans R.Br is presented. Conclusions: This study concludes that molecular differentiation between resins from different species is still possible after a hundred years of aging in a museum environment and demonstrates the potential of resin analysis on such aged museum items. These data alongside re-visited ethnographic accounts can confirm, correct, or provide new information to museum records. Furthermore, they can shed new light on the study of the role of these particular resins and mixtures that were used in Indigenous Sahul and contribute towards a framework of analysis and understanding of archaeological resins from this region.
