摘要

 利用固相微萃取和GC-MS联用技术对闽鄂山茶(Camellia grijsii Hance)及其芽变品种‘珍珠茶’(‘Zhenzhucha’)的完整花、花瓣和雄蕊香气组成成分的相对含量进行检测分析。结果表明:闽鄂山茶和‘珍珠茶’花的香气组成成分分别有37和30种,总相对含量分别为458.92和126.44;二者共有成分有23种,且均以芳樟醇的相对含量最高,多数共有成分在闽鄂山茶中的相对含量明显高于‘珍珠茶’。闽鄂山茶花瓣和雄蕊的香气组成成分分别有35和44种,‘珍珠茶’花瓣和雄蕊的香气组成成分分别有40和39种;闽鄂山茶雄蕊主要香气组成成分的总相对含量明显高于其花瓣,而‘珍珠茶’花瓣和雄蕊主要香气组成成分的总相对含量相近。比较而言,闽鄂山茶的花香气更加浓郁,其花香气可能主要来源于雄蕊,而花瓣和雄蕊可能均是‘珍珠茶’花香气释放的主要部位。

Abstract

The relative contents of aroma components of entire flowers, petals, and stamens of Camellia grijsii Hance and its bud mutation cultivar ‘Zhenzhucha’ were detected and analyzed by combining technology of solid phase micro-extraction and GC-MS. The results show that flowers of C. grijsii and ‘Zhenzhucha’ have 37 and 30 aroma components respectively, and their total relative contents are 458.92 and 126.44 respectively; there are 23 common components between them, the relative content of linalool is the highest, and the relative contents of most common components in C. grijsii are evidently higher than those in ‘Zhenzhucha’. Petals and stamens of C. grijsii have 35 and 44 aroma components respectively, while those of ‘Zhenzhucha’ have 40 and 39 aroma components respectively; the total relative content of main aroma components in stamens of C. grijsii is obviously higher than that in petals, while the total relative contents of main aroma components in petals and stamens of ‘Zhenzhucha’ are close. In comparison, the flower aroma of C. grijsii is stronger, maybe its flower aroma is mainly derived from stamens, while both petals and stamens are probably the main emission parts of flower aroma of ‘Zhenzhucha’.
