摘　　要：从感观评价和化学成分方面,对越南红土沉香与越南黄熟香、吊口沉香以及报道的奇楠沉香和普通沉香进行比较,结果发现:红土沉香木心为紫褐色;与报道的奇楠沉香比较,奇楠沉香油脂丰富,易于切割成卷,而红土沉香油脂含量不高(6.16%),较硬,不易切割。采用GC-MS技术分析越南红土沉香、黄熟香和吊口沉香乙醚提取物的化学成分和相对含量,发现红土沉香油脂中2-(2-苯乙基)色酮和2-[2-(4-甲氧基)苯乙基]色酮的相对含量之和高达51.57%,其油脂的成分组成与奇楠沉香油脂接近,而黄熟香和吊口沉香中二者相对含量之和分别为0.77%和0.78%。说明红土沉香是介于普通沉香与奇楠沉香之间,质量更接近于奇楠沉香。In this article, agarwood ＂Hong Tu＂ was compared with agarwood ＂Huang Shu Xiang＂, ＂Diao Kou＂,＂Qi-Nan＂reported previously and ordinary agarwood from the side of organoleptic evaluation and chemical composition. It found that the colour of wood surface of ＂Hong Tu＂ was purple brown; agarwood ＂Hong Tu＂compared with agarwood ＂Qi-Nan＂ found that agarwood ＂Qi-Nan＂ was rich in resin and was easy to be cut in curly, while the resin content of agarwood ＂Hong Tu＂was not so high（6.16%）, and it was difficult to be cut. The chemical constituents and relative contents of the ether extracts of the three types of agarwood were analyzed by gas chromatography-mass（GC-MS） spectrometry. The relative content of compounds 2-（2-phenylethyl）chromone and2-[2-（4-methoxyphenyl）ethyl]chromone in ＂Hong Tu＂was 51.57%, which the constitute of resin gets close to ＂QiNan＂, while the relative content of the two compounds in ＂Huang Shu Xiang＂and ＂Diao Kou＂ was 0.77% and0.78%, respectively. The results indicated that the quality of ＂Hong Tu＂ was between ordinary agarwood and ＂QiNan＂, while it was closer to agarwood ＂Qi-Nan＂.
