采用1,2,3,4-丁烷四羧酸(BTCA)在催化剂次亚磷酸钠(SHP)的作用下将β-环糊精(β-CD)接枝到真丝纤维上,然后浸渍加入具有驱蚊功效的薰衣草精油使其包合在β-CD空腔中,制备出具有驱蚊功效的真丝织物。设计单因素试验优化β-CD接枝真丝织物的工艺参数,当BTCA和β-CD的质量浓度分别为100 g/L,SHP的质量浓度为60 g/L,170℃下焙烘3 min或180℃下焙烘2 min,真丝织物的接枝增重率可达18.4%,红外光谱分析表明β-CD已成功接枝至真丝织物上,且可耐15次以上的水洗。接枝β-CD的真丝织物能够赋予薰衣草精油缓释的效果,且放置8 d后对按蚊仍可保持75%以上的驱避率。此方法制备的防蚊真丝织物效果持久可重复使用,且具有对人体无毒害、环保的特点。 相似文献

Methods to reduce the effects of acute stress could benefit the equine industry; therefore, the objective of this experiment was to determine whether aromatherapy would hasten the recovery time in acute-stressed horses. A total of seven horses were used in this experiment, using a crossover design where each horse received each treatment 7 days apart. The heart rates (HRs) and respiratory rates (RRs) were recorded for each horse at rest in stalls; then an air horn was blown twice for 15 seconds. The horses were allowed 60 seconds to calm, and then the stressed HRs and RRs were recorded. Control-treated horses were then exposed to humidified air, whereas aromatherapy-treated horses were exposed to humidified air with a 20% mixture of 100% pure lavender essential oil for 15 minutes. Following the 15-minute control or aromatherapy treatment, the recovery HRs and RRs were recorded (15 minutes). There were no statistical differences (P > .05) between the control and aromatherapy treatment for resting HR 33.7 ± 3.6 versus 34.0 ± 3.1 beats per minute (bpm), or change to increased HR in response to the air horn. However, the change in HR, after treatment, was significantly greater (P < .02) after aromatherapy (−9.25 ± 3.4 bpm) compared with the control treatment (0.29 ± 1.5 bpm). The RR did not differ (P > .05) between the control or aromatherapy treatment groups for the resting RR or change in RR. These results demonstrate that lavender aromatherapy can significantly decrease HR after an acute stress response and signal a shift from the sympathetic nervous control from the parasympathetic system. 相似文献

Generation and characterisation of colchicine-induced autotetraploid Lavandula angustifolia 总被引：1，自引：0，他引：1
Lavandula angustifolia (lavender) is a small woody perennial grown for essential oil, which is steam distilled from flowers. To potentially improve
size of flowers and oil yield we produced and characterised autotetraploid plants. L. angustifolia seed germinated in the presence of the mitotic spindle inhibitor colchicine at concentrations of 125 mg l−1 or less resulted in plants carrying sports with larger flowers. Propagation of two sports gave rise to putative polyploid
cultivars C3/2 and C6/24. Direct chromosome counts in root tip cells of seedlings from four common cultivars of L. angustifolia and the seed lot from which C3/2 and C6/24 were derived was 50 whereas C3/2 and C6/24 had greater than 90 chromosomes indicating
they were autotetraploid. Ploidy level assessed by flow cytometry (FCM) of nuclei showed that 12 cultivars of L. angustifolia had similar nuclear DNA content whereas C3/2 and C6/24 had double the amount of DNA confirming autotetraploidy. The genome
size (1C-value) of a diploid L. angustifolia cultivar was estimated by FCM to be 0.90 (±0.07) pg. Morphological characteristics were measured in autotetraploid and control
plants. Autotetraploids had thicker peduncles, larger flowers and larger seeds than diploids. Scanning electron microscopy
revealed peltate glandular trichomes were larger in the tetraploids relative to diploids. Both tetraploid and diploid cultivars
had complex non-glandular trichomes on leaves and sepals and two different types of capitate glandular trichomes were identified
on leaves. Autotetraploid lavenders represent useful germplasm both for commercial oil production and future breeding. 相似文献
