摘要:

为构建台湾独蒜兰组培繁育技术体系,分析栽培台湾独蒜兰假鳞茎化学组成特征,经过种子萌发、原球状茎增长、假鳞茎增殖、生根壮苗培养获得台湾独蒜兰植株,以组培台湾独蒜兰植株的假鳞茎为材料,应用非靶向代谢组和HPLC指纹图谱分析假鳞茎化学成分组成。结果表明,经过2年的繁育,单个台湾独蒜兰蒴果可以获得假鳞茎0.5 g左右的幼苗超过1 000株。通过非靶向代谢组数据分析鉴定出不同材料的共有的化合物1 229种,包括羧酸及其衍生物236种、苯及取代衍生物110种、有机氧化合物106种、脂肪酰基化合物94种、黄酮类化合物43种、甾体及甾体衍生物42种,其中以化合物1,4-二[4-(葡萄糖氧)苄基]-2-异丁基苹果酸酯为代表的苄酯类为兰科植物富集化合物。应用HPLC法,测得假鳞茎的1,4-二[4-(葡萄糖氧)苄基]-2-异丁基苹果酸酯含量为0.53%。综上,应用组培技术可以繁育得到台湾独蒜兰的植株,台湾独蒜兰的假鳞茎与独蒜兰一样含有丰富的苄酯类化合物成分。

Abstract:

The aim of this study was to construct the tissue culture and breeding technology system of Pleione formosana Hayata, and analyze the chemical composition characteristics of pseudobulbs of P. formosana Hayata. After seed germination, protocorm growth, pseudobulb proliferation, rooting and seedling culture, the plants of P. formosana Hayata were obtained. The pseudobulbs of tissue-cultured P. formosana Hayata plants were used as materials. The chemical composition of pseudobulbs was analyzed by non-targeted metabolomics and HPLC fingerprint. After 2 years of breeding, more than 1 000 seedlings with about 0.5 g pseudobulbs were obtained from a single capsule. Through the analysis of non-targeted metabolomics data, 1 229 common compounds were identified in different materials, including 236 carboxylic acids and their derivatives, 110 benzene and substituted derivatives, 106 organic oxygen compounds, 94 fatty acyl compounds, 43 flavonoids, and 42 steroids and steroid derivatives. Among them, the benzyl esters represented by 1,4-bis [4-(glucoseoxy) benzyl]-2-isobutylmalate are orchid-enriched compounds. Meanwhile the content of 1,4-bis [4-(glucoxy ) benzyl]-2-isobutylmalate was 0.53% in pseudobulbs detected by HPLC. The plants of P. formosana Hayata can be bred by tissue culture technology. And the pseudobulbs of P. formosana Hayata are rich in benzyl ester compounds as well as P. bulbocodioides(Franch.) Rolfe.
