竹醋液的精制方法探讨 总被引：4，自引：0，他引：4
采用减压蒸馏法、活性炭吸附法、澄清剂法对竹醋液原液进行精制，并采用气相色谱一质谱联用仪（GC-MS)对竹醋液原液和3种精制竹醋液组分进行分析比较。结果表明：采用减压蒸馏法精制竹醋液效果最好，话性炭吸附法效果次之，而澄清剂法效果较差；竹醋液是一种成分较复杂的混合物，其主要成分是水，其次是有机酸，醛类，醇类等物质；竹醋液的组分含量因精制方法不同而会引起成分的变化。 相似文献

竹醋液馏分抑菌性能研究 总被引：11，自引：0，他引：11
为了探索竹醋液不同组分的抑菌性能,在不同条件下蒸馏分离竹醋液得到各种馏分.以大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌、啤酒酵母、黑曲霉为对象开展竹醋液馏分的抑菌性能实验.结果表明,多数条件下蒸馏分离的馏分其抑菌性能不及竹醋液原液,仅有一种馏分的抑菌效果较突出.优化该馏分的制备工艺,在蒸馏温度70 ℃、真空度0.1 MPa下,调节竹醋液pH值为6.0,预蒸出原液体积25 %、再将剩余液pH值调至竹醋液原值,蒸馏得到50 %原液体积的馏分,此馏分抑菌效果最佳,其各项抑菌指标均优于竹醋液原液. 相似文献

贮藏过程竹醋液组分及其含量的差异分析 总被引：6，自引：0，他引：6
该文对自燃炉生产的新鲜竹醋液和经6个月贮藏的老化竹醋液的基本理化性质及其组分和含量进行比较分析.结果表明,新鲜竹醋液的颜色较深且不透明,老化竹醋液色泽变红且透明,新鲜竹醋液的折光率、总酸含量分别较老化竹醋液高10.66%和45.98%,pH值老化竹醋液比新鲜竹醋液低;利用气质联用仪进行成分分析,结果表明新鲜竹醋液有机物种类114种,老化竹醋液97种,老化竹醋液中有机酸、酚类、醛类、醇类、酯类含量分别比新鲜竹醋液高18.08%、20.36%、55.97%、245.76%、69.86%,而酮类和其它成分含量比新鲜竹醋液低0.36%和28.26%. 相似文献

竹醋液作为植物生长调节剂的开发研究：室内和田间试验 总被引：3，自引：0，他引：3
本文采用萝b子叶扩张法,萝卜、小麦和黄瓜的幼苗生长法,分别对原竹醋液和中和竹醋液进行室内生物活性筛选试验。结果表明：（1）低浓度（〈500mg／L）,具有植物生长调节剂功效,其功能与2,4-D类、激素类除草剂相似;高浓度竹醋液（2000—5000mg／L）抑制作物生长,具有除草剂活性;也与植物生长调节剂GA,和6-BA具有相似的功效;（2）中和竹醋液的效果明显高于原竹醋液;（3）几种筛选指示物的敏感性从高到低的顺序为：萝卜子叶〉黄瓜根茎长〉萝卜根茎长〉小麦根茎长,其中对于黄瓜、萝卜和小麦,根长敏感性均高于茎长。对原竹醋液和中和竹醋液在苹果、柑橘、草莓等作物上进行应用试验。表明：竹醋液不仅显著地提高农林作物的产量;具有明显改善叶片质量,延长叶片寿命,提高果实硬度从而改善果实的储藏品质,改善果品的内在品质和外观品质等功能;在调节果实成熟期减少锈斑面积、落叶、落果和病害等方面均有显著作用。 相似文献

竹酢液对杉木苗木生长效应和土壤肥力影响的研究 总被引：4，自引：0，他引：4
通过杉木幼苗的盆栽试验,采用喷施及土壤施入两种施用方法及9个不同浓度处理,分析施用竹酢液后对土壤化学性质以及杉木苗高和地径生长的影响。结果表明:施用竹酢液后,土壤pH无明显变化;H50和P300两种处理可以明显提高土壤全氮和速效磷含量,降低苗木生长过程中土壤速效钾、碱解氮和有机质等指标含量的衰减程度;促进土壤脲酶、多酚氧化酶和过氧化物酶的活性;对苗高和地径的生长有明显的促进作用。总体看来,适宜浓度的竹酢液对提高杉木人工林土壤肥力,促进杉木生长有利,其应用前景广泛。 相似文献

Effect of bamboo vinegar on regulation of germination and radicle growth of seed plants 总被引：10，自引：0，他引：10
Two kinds of bamboo vinegar from madake bamboo (Phyllostachys bambusoides) and moso bamboo (Phyllostachys pubescens) were prepared to analyze their components by gas chromatography (GC). The original vinegar, distilled vinegar, ether-extracted
vinegar, and three fractions including acidic, neutral, and phenolic fractions separated from ether-extracted vinegar were
diluted with distilled water 102 to 107 times. These diluted vinegar solutions were used to investigate the effect of bamboo vinegar on the germination and radicle
growth of seed plants. High concentrations of all kinds of treated bamboo vinegars (e.g., 102 of original vinegar and 103 of ether-extracted vinegar) showed strong inhibition against germination of the seeds. However, an appropriate dilution of
bamboo vinegar showed an obvious promotional effect on germination and radicle growth for the four kinds of tested seeds (lettuce,
watercress, honewort, chrysanthemum).

1 Introduction Bamboo vinegar is a condensed acidic liquid obtained in the process of producing bamboo charcoal. It has a special smoky odor and its color is light-yellow to brown. There are over 200 kinds of chemical compo- nents involved and these components mainly include organic acids, phenolic, alkone, alcohol and ester compounds. Of these, acetic acids are the main com- ponents, accounting for about 50% of the organic chemicals. Bamboo vinegar has been found to have an effect on improvi… 相似文献

Moso bamboo vinegar was treated with extractive and separation methods. The acidic, neutral, and phenolic fractions separated from ether-extracted vinegar were analyzed by gas chromatography and gas chromatography-mass spectrometry to identify the major components in moso bamboo vinegar. The compositions of eight moso vinegar fractions collected over different temperature ranges from 100°C to 480°C were also analyzed and their effects on regulation of germination and growth were studied by bioassay with seeds of watercress and chrysanthemum. The results showed that moso bamboo vinegar fractions with collection temperatures up to 250°C promoted radicle and hypocotyl growth and this effect became larger with increasing collection temperature for chrysanthemum. Moso bamboo vinegar collected from 250°C to 400°C had a strong inhibition on germination and radicle growth for both seed types when tested at 103 dilution. 相似文献
