露兜兰属植物是著名的观赏植物，其花芳香宜人。中国云南是分布最广的一个地区。采用固相微萃取-气相色谱-质谱联用技术（SPME-GC-MS）对不同花发育阶段的紫露草挥发性有机物（VOCs）进行了分析。的花挥发物多态性的评价。将峰面积归一化为百分比，并用于测定挥发物的相对量。结果表明，在4个不同发育阶段共鉴定出39种化合物。其中蕾期26株，初花期26株，盛花期32株，终花期32株。含量最高的化合物是丹皮酚（51%-83%），其次是（E，E）-α-法呢烯、环萨文和δ-杜松烯。所有这些挥发性化合物创造了L.铁杉花花香的散发呈先升后降的趋势，在初花期达到高峰。花挥发物的多样性在花发育的第三期和后期最丰富。主成分分析表明，在整个花发育过程中，花香味成分及其相对含量存在差异。研究结果对今后香菊属植物的花香育种具有重要意义。L.铁线蕨是一种有益的室内植物，由于其主要的花香化合物具有许多药用特性，因此除了作为芳香的观赏植物外，铁线蕨还具有作为精油开发的良好前景。
Luculia plants are famed ornamental plants with sweetly fragrant flowers, of which L. pinceana Hooker, found primarily in Yunnan Province, China, has the widest distribution. Solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) was employed to identify the volatile organic compounds (VOCs) emitted from different flower development stages of L. pinceana for the evaluation of floral volatile polymorphism. Peak areas were normalized as percentages and used to determine the relative amounts of the volatiles. The results showed that a total of 39 compounds were identified at four different stages of L. pinceana flower development, including 26 at the bud stage, 26 at the initial-flowering stage, 32 at the full-flowering stage, and 32 at the end-flowering stage. The most abundant compound was paeonol (51%–83%) followed by (E,E)-α-farnesene, cyclosativene, and δ-cadinene. All these volatile compounds create the unique fragrance of L. pinceana flower. Floral scent emission offered tendency of ascending first and descending in succession, meeting its peak level at the initial-flowering stage. The richest diversity of floral volatile was detected at the third and later periods of flower development. Principal component analysis (PCA) indicated that the composition and its relative content of floral scent differed throughout the whole flower development. The result has important implications for future floral fragrance breeding of Luculia. L. pinceana would be adequate for a beneficial houseplant and has a promising prospect for development as essential oil besides for a fragrant ornamental owing to the main compounds of floral scent with many medicinal properties.
