A previously undescribed fatty acid, all-cis 7,11-20:2 (dihomotaxoleic acid, DHT), has been characterized by gas chromatography-mass spectrometry as being present (approximately 0.1%) in seed oils of two Taxaceae containing high levels (11-16%) of taxoleic acid (all-cis 5,9-18:2). This compound was absent from oils of 10 other conifer genera, as well as from one member of Taxaceae containing very low amounts of taxoleic acid, suggesting that DHT is a taxoleic acid elongation product.
一种先前未被描述的脂肪酸，全顺式7,11-二十碳二烯酸（二高紫杉油酸，DHT），已通过气相色谱-质谱法鉴定出存在于两种红豆杉科植物的种子油中（含量约为0.1%），这两种植物的种子油中含有高水平（11-16%）的紫杉油酸（全顺式5,9-十八碳二烯酸）。在其他10个针叶树属的种子油中以及在一种紫杉酸含量极低的红豆杉科植物中均未发现该化合物，这表明DHT是紫杉油酸的延伸产物。
