- 摘要:
- 以玉兰花与广玉兰花为试材，研究了花苞期、花蕾期、初花期、盛花期、终花期2种玉兰花总黄酮含量和总酚含量的变化。结果表明：同一花期广玉兰花中总黄酮含量高于玉兰花中的含量，不同花期表现不一；玉兰花在盛花期中总黄酮含量达到最高，为7.63 mg/g，而广玉兰花总黄酮含量在花蕾期最高，为19.3 mg/g；但总酚含量在花苞期和花蕾期的广玉兰花要高于玉兰花，而在初花期、盛花期和终花期的广玉兰花总酚含量低于玉兰花的；玉兰花中总酚含量在盛花期达到最高，为56.61 mg/g，广玉兰花中总酚含量在花蕾期最高，为76.80 mg/g。
- Abstract:
- Taking Magnolia denudata and M.grandiflora as materials,the contents of total flavonoids and total phenols from flower of Magnolia denudata and M.grandiflora in the early blooming stage，bud stage，first opening stage，full flowering stage，and final flowering were determined.The results showed that the content of total flavonoids from flower of M.grandiflora was higher than flower of M.denudata in same florescence，but the different florescent were different.In full flowering stage，the content of total flavonoids of M.denudata reached the highest, 7.63 mg/g，and the maximum content of M.grandiflora was bud stage，reached 19.30 mg/g.The content of total phenols from flower of M.grandiflora was higher than flower of M.denudata in two stages.They were early blooming stage and bud stage.Whereas in first opening stage，full flowering stage，and final flowering the content of total phenols from flower of M.grandiflora was lower than flower of M.denudata.The content of total phenols from flower of M.grandiflora was rising with florescence，and the highest content was observed in full flowering stage reached 56.61 mg/g.And the content of total phenols of M.grandiflora was highest in bud stage reached 76.80 mg/g.
