The mixture of bark and gum obtained after size-grading of Siam benzoin gum was studied to establish its potential application as a valuable new grade of the balsamic resin. An analysis of its volatile constituents by means of static headspace and SPME led to the identification of 26 and 50 compounds, respectively. Significant differences were observed in both the headspace composition and olfactory properties of the byproduct as compared to those of Siam benzoin gum. This prompted the further analysis of its volatile extract and its resinoid by GC techniques, resulting in the identification of 60 (99.5%) and 16 (89.1%) components, respectively. To examine the influence of bark pieces, different extracts obtained from the raw material and from a sorted sample were analyzed by GC and HPLC techniques. The chemical compositions and the yields determined for the two resinoids lead to the conclusion that this harvesting byproduct is a new grade of Siam benzoin gum, providing interesting olfactory notes that differ from those of other grades.
对暹罗安息香树胶进行粒度分级后得到的树皮与树胶混合物进行了研究，以确定其作为一种有价值的新型香脂树脂的潜在应用。通过静态顶空和固相微萃取对其挥发性成分进行分析，分别鉴定出了26种和50种化合物。与暹罗安息香树胶相比，该副产品的顶空成分和嗅觉特性均存在显著差异。这促使通过气相色谱技术对其挥发性提取物和树脂类提取物进行进一步分析，分别鉴定出了60种（99.5%）和16种（89.1%）成分。为了研究树皮碎片的影响，采用气相色谱和高效液相色谱技术对从原材料和分选样品中获得的不同提取物进行了分析。两种树脂类提取物的化学成分和产率得出的结论是，这种收获副产品是一种新型的暹罗安息香树胶，具有与其他等级不同的有趣嗅觉特征。
