摘要
本试验旨在测定贵州不同保健功能性植物标志性成分含量,比较不同加工炮制方法对天然植物胡萝卜素含量的影响。为此,采集贵州9个市(州)同一生育期的青蒿茎叶、野生金荞麦茎叶、杜仲叶、鱼腥草茎叶、茶叶新鲜样10kg/份,分为2份,一份鲜样测定青蒿中青蒿素(mg/g)、金荞麦中芦丁含量(mg/g)、杜仲叶中黄酮含量(mg/g)、鱼腥草中黄酮含量(mg/g)、茶叶中茶多酚含量(mg/g);另外一份进行晒干(简称"晒干")、灭活后烘干(简称"温干")、高温烘干(简称"快干")、油制灭活焙干(简称"油焙")共4种不同炮制方法处理,以胡萝卜素保存率为对比指标进行比较试验。结果:1)贵州9个市(州)5种天然保健功能性植物标志性成分含量处于中高水平,可以作为保健功能性植物添加至畜禽动物饲料中;2)4种加工方式中,胡萝卜素保存率由低到高为:油焙>快干>温干>晒干。本试验油焙、快干、温干和晒干对5种保健功能性植物胡萝卜素保存率分别介于92.7%~96.1%、81.5%~86.1%、57.3%~65.0%和15.4%~26.1%之间。
This research is implemented to analyze some symbolic indexes of Chinese herbal medicine plant sand compare the content ofβcarotene between different processing technologies.We collet some fresh samples,such as wild A.annua,wild bitter Buckwheat,Eucommia ulmoildes leaf,Herba Houttuyniae and tea leaf which wereat the same growing period,from nine different places in Guizhou province,and depart them into two groups with 10kg each.Some symbolic indexes content were detected in one fresh sample:the artemisinin in wild Artemisia annua(mg/g),the rutin in wild bitter Buckwheat(mg/g),the flavonoids f rom Eucommia ulmoildes leaf(mg/g)and in Herba Houttuyniae(mg/g),and the polyphenols from tea leaf(mg/g).The other samples are processed to contrast the c o nte nt ofβc arote ne f rom four processing ways by sundr ying(abbreviated as sundrying),baking after deactivation(mode rate-drying),high temperature baking(qu ick-drying)or oil-baked ustulating after deactivation(oil-baking).Results showed that:1)the symbolic indexes content are medium-to-high level in the five Chinese herbal medicine plants,therefore these plants can be mixed into the feed as functional a d d i t i ve s;2)the content ofβ-carotene from four different processing ways are oil-baking>quick-drying>moderatedr ying>sun-drying with the ratio of 92.7%~96.1%,81.5%~86.1%,57.3%~65.0%and 15.4%~26.1%,respectively.
