Abstract An experiment was conducted to evaluate the phenolic acids and flavonoids contents from flower bud to flower senescence stages (7 stages) in cut H3O roses every other day. Some phenolic acids (Gallic, Caffeic, Caftaric, Chlorogenic, Chicoric, Coumaric, Sinapic, and Ferulic) and flavonoids (Catechin, Pelargonidin chloride, Cyanidin, Kaempferol, and Quercetin) were detected in the methanolic extract of rose petals by HPLC. Data analysis revealed that Gallic acid content did not significantly (P ≤ 0.05) affects from the flower bud to the senescence stages. However, it’s found that Caftaric acid, Chlorogenic acid, Coumaric acid, Ferulic acid, Chicoric acid, Quercetin, and Kaempferol (at P ≤ 0.05), Catechin, Caffeic acid, Sinapic acid, Cyanidin, and Pelargonidin chloride contents (at P ≤ 0.01) significantly affected during flower opening stages. The highest contents of phenolics during development of cut H3O rose flowers were as follow: day 1 [Coumaric acid], day 3 [Caftaric acid, Ferulic acid, and Kaempferol], day 5 [no compound was found], day 7 [Sinapic acid and Cyanidin], day 9 [Chlorogenic acid], day 11 [Chicoric acid and Quercetin], and day 13 [Caffeic acid, Catechin, and Pelargonidin chloride]. The results showed that flower development stages can be suggested to consider the phenolic compounds required to use in the therapeutic process.

花发育过程中切开的 H3O 月季花的酚类模式

摘要 以隔日切开的H3O玫瑰花蕾至花衰老阶段（7个阶段）的酚酸和黄酮类化合物含量为研究对象。HPLC 在玫瑰花瓣的甲醇提取物中检测到一些酚酸（没食子酸、咖啡酸、Caftaric、绿原、菊苣、香豆酸、芥子酸和阿魏酸）和黄酮类化合物（儿茶素、氯化天竺葵素、花青素、山奈酚和槲皮素）。数据分析表明，没食子酸含量从花蕾到衰老阶段没有显着影响（P ≤ 0.05）。然而，发现咖啡酸、绿原酸、香豆酸、阿魏酸、菊苣酸、槲皮素和山奈酚（P ≤ 0.05）、儿茶素、咖啡酸、芥子酸、花青素和氯化天竺葵素的含量（P ≤ 0） . 01) 在开花期显着影响。在切开的 H3O 月季花发育过程中酚类物质的最高含量如下：第 1 天 [香豆酸]、第 3 天 [咖啡酸、阿魏酸和山奈酚]、第 5 天 [未发现化合物]、第 7 天 [芥子酸]和花青素]、第 9 天 [绿原酸]、第 11 天 [菊苣酸和槲皮素] 和第 13 天 [咖啡酸、儿茶素和氯化天竺葵素]。结果表明，可以建议花发育阶段考虑治疗过程中所需的酚类化合物。第 11 天 [菊苣酸和槲皮素] 和第 13 天 [咖啡酸、儿茶素和氯化天竺葵素]。结果表明，可以建议花发育阶段考虑治疗过程中所需的酚类化合物。第 11 天 [菊苣酸和槲皮素] 和第 13 天 [咖啡酸、儿茶素和氯化天竺葵素]。结果表明，可以建议花发育阶段考虑治疗过程中所需的酚类化合物。
