Evaluation of proline, chlorophyll, soluble sugar content and uptake of nutrients in the German chamomile (Matricaria chamomilla L.) under drought stress and organic fertilizer treatments

Objective: To investigate the effect of drought stress and organic fertilizer on German chamomile(Matricaria chamomilla) nutrient uptake, leaf chlorophyll content and osmotic adjustment under field conditions.Methods: This experiment was carried out through a randomized complete block design with a split factorial arrangement of treatments in three replications. The main plots were subjected to the following irrigation treatments: irrigation after 60, 90, 120, 150 and180 mm evaporation from Class A pan. The sub-plots were treated with three vermicompost doses(0, 5 and 10 t/ha).Results: Although drought stress reduced the nutrient percentages in the shoots, application of vermicompost enhanced the nutrient percentages, particularly when the plants were subjected to moderate to severe drought stress conditions. Moreover, the results of this study showed that the interaction between irrigation treatments and vermicompost rates on leaf chlorophyll content was significant. Comparison between the combined treatments indicated that under normal irrigation and moderate drought stress conditions chamomile plants received 5 and 10 t/ha vermicompost showed significantly higher leaf chlorophyll content comparing to the control treatment.Conclusions: Totally, organic fertilization by vermicompost could partly alleviate the effect of drought stress on chamomile by increasing N, P and K uptake and leaf soluble sugar, especially in stressed treatments.

Nephroprotective Effect of <i>Nigella Sativa</i>and <i>Matricaria Chamomilla</i>in Cisplatin Induced Renal Injury—Supportive Treatments in Cisplatin Nephrotoxicity

Nigella sativa and Matricaria chamomilla are extensively consumed as tea or tonic. Despite their widespread use as a home remedy, relatively few trials evaluated their benefits in nephroprotection. Hence, this study evaluates the nephroprotective effects of supportive treatments (N. sativa, M. chamomilla and vitamin E) in cisplatin nephrotoxicity rat model. Eighty rats divided into 10 groups, of 8 animals each. The first group (G1) injected with saline intra-pretoneal (i.p). G2 injected with 5 mg/kg cisplatin i.p on zero day of experiment and repeated 4 times, with 5 days free interval. G3-G10 received daily supportive treatments, started 5 days before the experiment (–5day). Concomitantly G4, G6, G8 and G10 injected with 5 mg/kg cisplatin i.p like G2. On day sixteen, animal scarified, serum and/or kidney tissue were used to determine kidney function tests (serum urea, creatinine, NAG, β-gal), oxidative stress indices (NO, LPO), antioxidant activities (SOD), sulphur compounds (GGT, GSH, total thiols ), apoptotic indices (cathepsin D, DNA fragmentation), two minerals (Ca2+ and zn2+). Cisplatin caused marked elevation in serum GGT that reduced signifi-cantly in group received M. chamomilla with cisplatin (P < 0.001). There is a correlation between GGT and NAG in cisplatin group (r = 0.731 p < 0.05) that may suggest one of possible mechanisms of renal injury by cisplatin. M. chamomilla followed by N. sativa and vitamin E improved the biochemical and pathological renal injury, as determined by increasing the body weight, normalizing the kidney functions, decreasing the oxidative stress markers, improving the apoptotic markers, minimizing the pathological changes. Hence, N. sativa and M. chamomilla will be a promising nephroprotective agents for reducing cisplatin nephrotoxicity, most probably, by antioxidants effects and inhibition GGT production, respectively.

NaCl胁迫对洋甘菊种子萌发与幼苗生长和生理指标及解剖结构的影响

对质量浓度0.2%、0.4%、0.6%、0.8%、1.0%、1.2%和1.4%NaCl胁迫条件下洋甘菊(Matricaria chamomillaLinn.)种子萌发状况、幼苗生长和叶片部分生理指标的变化进行了分析,并采用石蜡切片法观察了NaCl胁迫后洋甘菊不同器官横切面解剖结构的变化。结果表明:随NaCl质量浓度提高,洋甘菊种子的相对萌发率、发芽势和萌发率均逐渐降低、相对盐害率逐渐增大;幼苗根长、株高及单株鲜质量和干质量均逐渐下降,但根长的降幅大于株高、鲜质量的降幅大于干质量;叶片中叶绿素含量呈先升高后下降的趋势,而可溶性糖和脯氨酸含量以及POD活性总体上呈逐渐增加的趋势。在NaCl胁迫条件下,种子相对萌发率、发芽势和萌发率均极显著(P<0.01)或显著(P<0.05)低于对照(0.0%NaCl),且除0.2%NaCl处理组外其他处理组的相对盐害率均极显著高于对照;而在质量浓度1.4%NaCl胁迫条件下洋甘菊种子均不能正常萌发。在NaCl胁迫条件下,各处理组幼苗根长、株高以及单株鲜质量和干质量均显著或极显著低于对照,叶片可溶性糖和脯氨酸含量及POD活性均显著或极显著高于对照;除1.2%NaCl处理组外,其他处理组叶绿素含量也均极显著高于对照。在NaCl胁迫条件下,洋甘菊植株形态及不同器官横切面解剖结构发生明显变化。随NaCl质量浓度提高,洋甘菊植株表现出株高矮小且植株干硬、叶片变小且肉质化程度增大等现象。经0.6%NaCl胁迫处理12个月后,洋甘菊茎横切面皮层内厚角组织数量及薄壁组织中气隙数量增加且维管束内导管更加发达;根横切面皮层内气隙数量增多、维管柱内导管较为发达;叶片横切面叶轴薄壁组织中气隙数量增加、叶片表皮皱缩且栅栏组织层数明显增多。综合分析结果表明:洋甘菊对NaCl胁迫具有一定的耐性,但高浓度NaCl胁迫对洋甘菊种子萌发、幼苗生长及形态均有明显影响。

Residual dynamics of thiacloprid in medical herbs marjoram,thyme,and camomile in soil

Thiacloprid is a new insecticide of the chloronicotinyl family. To assess its risk after application, residual characteristics of thiacloprid in marjoram, thyme, and camomile and in soil were studied under field conditions. The active ingredient was extracted from the plant material using a mixture of acetone-water. After filtration, the extract was concentrated to the aqueous phase, diluted with water, and portioned against ethyl acetate on a matrix solid phase dispersion column. Thiacloprid was extracted from soil using a mixture of methanol-water, filtered, and re.extracted （clean up） with dichloromethane. The residues were quantified using HPLC-MS-MS. The methods were validated by recovery experiments. Thiacloprid residues in marjoram, thyme, and camomile and in soil persisted beyond 10, 14, 14, and 21 d but no residues were detected after 14, 21, 21, and 28 d, respectively. The data obtained in this study indicated that the biexponential model is more suitable than the first-order function to describe the decline of thiacloprid in fresh marjoram, fresh thyme, and dried camomile flowers with half-life （t1/2） of 1.1, 0.7, and 1.2 d, respectively. However, both the first-order function and biexponential model were found to be applicable for dissipation of thiacloprid in soil with almost the same t1/2 values of 3.5 and 3.6 d. The results indicated that thiacloprid dissipates rapidly and does not accumulate in the tested herbs and in soil.

目的基于驱动蛋白家族3A基因(Kif3a)和Sonic hedgehog(SHH)信号通路探讨洋甘菊活性组分对脂多糖(LPS)诱导的人支气管上皮细胞(16HBE)的保护作用及机制。方法用脂多糖诱导人支气管上皮细胞建立哮喘炎症细胞模型。CCK-8法检测不同浓度洋甘菊活性组分对脂多糖诱导人支气管上皮细胞的增殖的抑制作用,筛选出最佳洋甘菊活性组分给药浓度。将细胞分为空白对照组、脂多糖模型组、阳性药物组(1μmol·L^(-1)地塞米松干预2 h)、洋甘菊活性组分组(200μg·mL^(-1),48 h)。Annexin V/PI结合流式细胞术检测各组的凋亡率。实时荧光PCR法和Western blot法检测Kif3a、SHH、Ptch1和Gli1的mRNA和蛋白表达变化。结果脂多糖干预后,可显著降低人支气管上皮细胞活力(P<0.05),并诱导其细胞凋亡(P<0.01)。洋甘菊活性组分在浓度200μg·mL^(-1)处理48 h时,可以显著逆转脂多糖对细胞的损伤并促进增殖(P<0.01),减弱脂多糖诱导的细胞凋亡(P<0.01)。与空白对照组比较,脂多糖诱导的人支气管上皮细胞内Kif3a在mRNA水平和蛋白表达水平显著降低(P<0.05),SHH、Ptch1、Gli1在mRNA水平和蛋白表达水平显著升高(P<0.05);与脂多糖模型组相比较,洋甘菊活性组分处理后可显著逆转mRNA水平和蛋白表达(P<0.05),增加Kif3a的mRNA水平和蛋白表达水平,并降低SHH、Ptch1、Gli1的mRNA水平和蛋白表达(P<0.05)。结论脂多糖诱导人支气管上皮细胞损伤,下调Kif3a水平从而上调SHH、Ptch1、Gli1水平,调控SHH信号通路处于异常激活状态。洋甘菊活性组分可显著逆转脂多糖诱导的细胞炎症损伤,上调Kif3a水平,下调SHH、Ptch1、Gli1水平,通过Kif3a调控SHH信号通路,对脂多糖诱导的人支气管上皮细胞发挥保护作用,改善哮喘气道炎症。

Improved antioxidative and cytotoxic activities of chamomile(Matricaria chamomilla) florets fermented by Lactobacillus plantarum KCCM 11613P

Antioxidative and cytotoxic effects of chamomile（Matricaria chamomilla） fermented by Lactobacillus plantarum were investigated to improve their biofunctional activities. Total polyphenol（TP） content was measured by the Folin-Denis method, and the antioxidant activities were assessed by the 1,1-diphenyl-2-picrylhydrazyl（DPPH） method and β-carotene bleaching method. AGS, HeL a, LoV o, MCF-7, and MRC-5（normal） cells were used to examine the cytotoxic effects by 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyltetrazolium（MTT） assay. The TP content of fermented chamomile reduced from 21.75 to 18.76 mg gallic acid equivalent（mg GAE）/g, but the DPPH radical capturing activity of fermented chamomile was found to be 11.1% higher than that of nonfermented chamomile after 72 h of fermentation. Following the β-carotene bleaching, the antioxidative effect decreased because of a reduction in pH during fermentation. Additionally, chamomile fermented for 72 h showed a cytotoxic effect of about 95% against cancer cells at 12.7 mg solid/ml of broth, but MRC-5 cells were significantly less sensitive against fermented chamomile samples. These results suggest that the fermentation of chamomile could be applied to develop natural antioxidative and anticancer products.

Effect of Matricaria chamomilla Hydroalcoholic Extract on Cisplatin-induced Neuropathy in Mice

AIM: Cisplatin-based chemotherapy is a mainstay for the treatment of solid tumors, especially colorectal, ovarian, testicular, bladder, and lung cancer. Studies have shown that cisplatin could have painful effects on human and animal models. Matri-caria chamomilla (MC) has analgesic and anti-inflammatory effects. The aim of this study was to investigate the effects of MC hydro-alcoholic extract on cisplatin-induced peripheral neuropathy and to compare with morphine in mice. METHODS: Experiments were performed on 60 NMRI male mice weighed 25 g to 30 g which have been divided into 6 groups. The first group received normal saline; the second group received MC hydroalcoholic extract; the third group received cisplatin; the fourth group received MC hydroalcoholic extract and cisplatin, 96 hours before formalin test; the fifth group received morphine and the sixth group received cisplatin and mor-phine. The time of injected hind paw biting and licking time were measured in 5-minute interval for an hour. RESULTS: Results showed that formalin induced significant (P < 0.05) pain response (the first phase: 0-5 min and the second phase: 15-40 min after injection). Administration of MC extract before formalin injection showed significant (P < 0.05) decrease of pain responses in the first and second phase. Administration of cisplatin produced significant (P < 0.05) increase in pain response in both phases of formalin test. Injection of MC extract and cisplatin together have shown that MC is able to decrease the second phase of cisplatin-induced pain sig-nificantly (P < 0.05). Morphine decreased cisplatin-induced pain in the first and second phase of formalin test significantly ( P < 0.05). In comparison morphine has analgesic effects in the first phase and MC extract has anti inflammatory effects in the second phase of formalin test significantly (P < 0.05). CONCLUSION: MC and cisplatin have analgesic and painful neuropathic respective effects, and MC hydroalcoholic extract is able to decrease cisplatin-induced pain and inflammation better than morphine.
