摘要
从“喜马拉雅日落蓝”圣罗勒(Ocimum tenuflorum)栽培品种的地上部分分离得到2个花青素、8个黄酮和4个酚类化合物。分别鉴定为花青素3-O-[(6‘″- e -对香豆醇基葡萄糖苷)-(1→4)-(6″- e -对香豆醇基葡萄糖苷)]-5- o -(6’″‘-丙二醇基葡萄糖苷)和花青素3-O-[- 6’″- e -对香豆醇基葡萄糖苷]-5- o -(6'″-丙二醇基葡萄糖苷)及其7- o -糖苷(黄酮类化合物)和香豆酸、球苷A、B和酚类化合物的蓝多苷。本研究对选定的6种化合物进行了抗氧化活性测定。此外,将天蓝草本茶‘Tulsi’中的两种主要色素花青素溶解在缓冲液中,并在间隔测量超过8 h的时间内测量其吸收光谱。这表明花青素中对香豆酸和葡萄糖的链结构有助于稳定颜色表达。
Identification of phenolic compounds from the aerial parts of Holy basil (Ocimum tenuiflorum) cultivar 'Himalayan Sunset Blue', their anti-oxidant activity, and anthocyanin contribution to colour stability.
Two anthocyanins, eight flavones, and four phenolic compounds were isolated from the aerial parts of Holy basil (Ocimum tenuiflorum) cultivar 'Himalayan Sunset Blue'. They were identified as cyanidin 3-O-[(6''″-E-p-coumaroylglucopyranosyl)-(1→4)-(6″-E-p-coumaroylglucopyranoside)]-5-O-(6″'-malonylglucopyranoside) and cyanidin 3-O-[glucopyranosyl-(1→4)-(6″-E-p-coumaroylglucopyranoside]-5-O-(6'″-malonylglucopyranoside) for anthocyanins, apigenin, luteolin, chrysoeriol and their 7-O-glycosides for flavones, and rosmarinic acid, globoidnans A and B, and rabdosiin for phenolic compounds. In this survey, antioxidant activity of selected six compounds was measured. Moreover, two anthocyanins which are main pigments in the sky-blue herb tea 'Tulsi', were dissolved the buffer solutions and were measured their absorption spectra under interval measurement over 8 h. It was suggested that the chain structure of p-coumaric acid and glucose in anthocyanins contributes to stable colour expression.
期刊介绍:
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
