Herbal medicine is still the mainstay of about 75–80% of the world population, mainly in the developing countries, for primary health care because of better cultural acceptability, better compatibility with the human body and lesser side effects. Natural products, including plants, animals and minerals have been the basis of treatment of human diseases. The current accepted modern medicine or allopathy has gradually developed over the years by scientific and observational efforts of scientists. However, the basis of its d velopment remains rooted in traditional medicines and therapies. Melia azedarach Linn, commonly known as mahanimba belongs to family Meliaceae. It is large evergreen tree found throughout India and very similar to neem. Traditionally it is used as anthelmintic, antilithic diuretic, emmenagouge, astringent and stomachic. Various scientific studies reported the analgesic, anticancer, antiviral, antimalarial, anti bacterial, anti feedent and anti fertility activity of this plant. So the objective of the present review is to highlight the phytochemical and pharmacological information of this plant.
草药仍然是世界上约75-80%人口(主要在发展中国家)初级卫生保健的支柱,因为它在文化上更容易接受,与人体的相容性更好,副作用更小。包括植物、动物和矿物在内的天然产品一直是治疗人类疾病的基础。目前公认的现代医学或对抗疗法是多年来通过科学家的科学和观察努力逐渐发展起来的。然而,其发展的基础仍然植根于传统药物和疗法。苦楝属苦楝科,俗称苦楝。它是一种遍布印度的大型常绿树木,与印度楝树非常相似。传统上用作驱虫药,抗结石利尿剂,按摩,收敛和胃。各种科学研究报道了该植物的镇痛、抗癌、抗病毒、抗疟、抗菌、抗食性和抗生育活性。因此,本文综述的目的是重点介绍该植物的植物化学和药理信息。

A field experiment according to simple randomized block design was conducted with the aim to find out the effects of foliar spray of thiamine hydrochloride (vitamin B1) on growth, nutrient uptake and yield characteristics of mustard (Brassica juncea L.) variety (Var.) Varuna. The plants were sprayed with 0.01, 0.02 and 0.03 wt% thiamine hydrochloride solution and a spray of distilled water was also maintained as a control. Spraying was done in a single spray after 40 days of sowing (DAS) i.e., at flower initiation stage (Ansari, 1988). The growth parameters studied include plant fresh weight, plant dry weight, leaf area (LA), leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR) and uptake of N and P at different growth stages. Yield as well as its components such as number of pods per plant, 1000 seed weight, yield, biological yield, harvest index, oil content and oil yield were measured at harvest. In general spray of 0.03 wt% of thiamine hydrochloride solution was found to be the best in comparison to any other concentration of the treatment for most of the parameters studied. Growth parameters like plant fresh weight, plant dry weight, CGR, RGR and NAR showed significant results at the early stages of sampling (that is, 60–80 DAS). In case of LA and LAI, there was no significant difference between thiamine hydrochloride spray treatments. Thiamine hydrochloride solution at 0.03 wt% was found significantly best in case of nitrogen uptake at 60 and 80 DAS while in case of phosphorous uptake, 0.02% was statistically the best; however, it was at par with 0.03 wt% thiamine hydrochloride solution at 80 DAS. Different yield parameters like the pod number per plant, biological yield and seed yield as well as oil yield registered significant results. The results suggest that the performance of B. juncea L. var. Varuna can be improved by spraying the plants with aqueous thiamine hydrochloride solution. Thus, it was concluded that the spray of thiamine hydrochloride solution ensured better growth and yield.
采用简单随机区组设计,研究了叶面喷施盐酸硫胺素(维生素B1)对芥菜(Brassica juncea L.) Varuna生长、养分吸收及产量特性的影响。分别用0.01、0.02和0.03 wt%盐酸硫胺素溶液喷淋植株,并保持蒸馏水喷雾作为对照。在播种40天后(DAS),即在开花阶段进行单次喷洒(Ansari, 1988)。研究的生长参数包括植株鲜重、干重、叶面积(LA)、叶面积指数(LAI)、作物生长率(CGR)、相对生长率(RGR)、净同化率(NAR)和不同生育期的氮磷吸收量。采收时测定单株荚果数、千粒重、产量、生物产量、收获指数、含油量和出油量等产量及其组成部分。总的来说,与任何其他浓度的处理相比,0.03 wt%盐酸硫胺素溶液的喷雾处理对大多数参数的研究都是最好的。植株鲜重、干重、CGR、RGR和NAR等生长参数在取样初期(即60-80 DAS)均有显著结果。在LA和LAI的情况下,盐酸硫胺素喷雾处理之间无显著差异。在60和80 DAS的氮吸收情况下,0.03 wt%的盐酸硫胺素溶液效果最好,而在磷吸收情况下,0.02%的硫胺素溶液效果最好;然而,在80 DAS时,与0.03 wt%盐酸硫胺素溶液相当。单株荚果数、生物产量、种子产量、油料产量等不同产量参数均有显著差异。结果表明,喷施盐酸硫胺素水溶液可提高芥菜的抑菌性能。由此可见,喷施盐酸硫胺素溶液能保证较好的生长和产量。

The leaves and flowers of Arnica plants contain ‘Helenalin’, a sesquiterpene lactone that is a major ingredient in anti-inflammatory preparations. It is a highly toxic compound, with hepatic and lymphatic tissues particularly vulnerable to its effects. It is responsible for the toxicity and skin irritation. Ingestion of these plants causes severe gastroenteritis and internal bleeding of the digestive tract. Moreover, they are potent and selective inhibitor of ‘human Telomerase’, which is partially accountable for its anti-tumour effects and has anti-trypanosome activity and is toxic to Plasmodium falciparum. In addition, it also retards the growth of Staphylococcus ureus and reduces the severity of S. aureus infection in humans. The roots of these plants contain derivatives of ‘Thymol (2-isopropyl-5-methylphenol)’, a fungicides and preservative. In addition, it has some anti-inflammatory effect, with strong antiseptic properties. Moreover, it is a biocide, agent with strong antimicrobial attributes, which reduces bacterial resistance to antibiotics, also an effective fungicide against fluconazole-resistant strains.
山金车的叶子和花含有“Helenalin”,这是一种倍半萜内酯,是抗炎制剂的主要成分。它是一种剧毒化合物,肝脏和淋巴组织特别容易受到它的影响。它具有毒性和刺激皮肤的作用。摄入这些植物会导致严重的胃肠炎和消化道内出血。此外,它们是“人类端粒酶”的有效和选择性抑制剂,端粒酶具有抗肿瘤作用,并具有抗锥虫活性,对恶性疟原虫有毒。此外,它还能延缓尿路葡萄球菌的生长,降低人体内金黄色葡萄球菌感染的严重程度。这些植物的根含有百里酚(2-异丙基-5-甲基苯酚)的衍生物,这是一种杀菌剂和防腐剂。此外,它还具有一定的抗炎作用,具有较强的防腐性能。此外,它是一种杀菌剂,具有很强的抗菌特性,可以降低细菌对抗生素的耐药性,也是一种有效的杀真菌剂,可以对抗氟康唑耐药菌株。

Nowadays, the use of absorbant polymers (hydrogels) for soil conditioning is considered an effective way to solve the problems of water limitation of sandy soils for reclamation of newly desert areas. In this work, the physical and chemical properties of the sandy soil mixed with different concentrations of five types of hydrogels were studied. The used hydrogels were polyacrylic acid (Aquakeep, AKG); sodium polyacrylate (Aqurihop); vinyl alcohol sodium polyacrylate (Igata, IGG); cellulose (Jelfine, JFG); and starch (Was, WG). The used concentrations of each hydrogel were 0.05, 0.1, 0.2 and 0.4% of the soil weight. The results demonstrated that the maximum water absorption capacity differed greatly from hydrogel to another. AKG and WG had the highest water absorption capacity, while JFG was the lowest indicating that using of AKG and/or WG is the best for water conservation in sandy soils. Moreover, for all used hydrogels, the moisture content of the sandy soil increased with all applied pF values at concentrations of 0.05 or 0.1% hydrogel. A decrease in the bulk density and increase in total porosity of the soil was noticed with the increase of the hydrogel concentration. Soil infiltration rate and hydraulic conductivity were decreased due to the increase in water-holding capacity by conditioning the soils with the used hydrogels. Chemical properties were improved by conditioning the sandy soils with studied hydrogels. All hydrogels could lower the pH values but increase the cation exchange capacity (CEC) of the soil depending on the hydrogel concentration. Using high concentration (0.4) of each hydrogel, the soil pH was slightly lowered, while CEC and organic matter were increased noticeably with more available NPK content (nitrogen, phosphorus, potassium content) in the conditioned soils. From overall experiments, addition of WG, IGG, AKG to the sandy soil appear to be the best for retaining moisture at field capacity, which provides more available water to the plants and caused improvement of physical and chemical properties of the sandy soil.
目前,利用吸收聚合物(水凝胶)对土壤进行调节被认为是解决新沙漠垦殖沙土水分限制问题的有效途径。本文研究了五种不同浓度的水凝胶对沙土理化性质的影响。所使用的水凝胶为聚丙烯酸(Aquakeep, AKG);聚丙烯酸钠;聚丙烯酸乙烯醇钠;纤维素(JFG);淀粉(Was, WG)。每种水凝胶的使用浓度分别为土壤重量的0.05、0.1、0.2和0.4%。结果表明,不同水凝胶的最大吸水量差异较大。AKG和WG的吸水能力最高,JFG的吸水能力最低,说明AKG和WG在沙质土壤中保水效果最好。此外,对于所有使用的水凝胶,在0.05或0.1%的水凝胶浓度下,所有施用的pF值都增加了沙土的含水量。随着水凝胶浓度的增加,土壤的容重减小,总孔隙度增大。用用过的水凝胶对土壤进行调节,使土壤的持水量增加,从而降低了土壤的入渗速率和导水率。用所研究的水凝胶对沙土进行调理,改善了沙土的化学性质。不同浓度的水凝胶均能降低土壤pH值,提高土壤阳离子交换容量(CEC)。当每种水凝胶浓度均为0.4时,土壤pH值略有降低,土壤CEC和有机质显著增加,有效氮磷钾含量(氮、磷、钾)增加。从整体试验结果来看,在沙土中添加WG、IGG、AKG对保持田间水分的效果最好,为植物提供了更多的有效水分,改善了沙土的理化性质。

In sericulture, diseases of silkworm host plants are the major constraint in realising the foliage potentiality of the plant under feeding of silkworms and the ultimate conversion of cocoons during crops. Diseases make the leaf unpalatable for muga silkworms and cause reduction in total leaf yield and ultimately affect cocoon yield production. In the present article, a survey of foliage diseases was carried out on one of the primary host plant Persea bombycina Kost. of Muga silkworm during the calendar year 2012 and 2013. It was observed that foliar diseases like red rust, leaf spot, grey blight and brown blight are common diseases occurring on the plant species in District Bageshwar of Uttarakhand state, which affects the foliage yield of the plant as well as quality and quantity of cocoon production.
在养蚕业中,蚕寄主植物的病害是实现蚕喂养下植物叶片潜力和作物期间茧最终转化的主要制约因素。病害使蚕蛹叶片难吃,导致叶片总产量降低,最终影响蚕茧产量。本文对一种主要寄主植物柏树(Persea bombycina Kost)的叶片病害进行了调查。在2012年和2013年的历年期间研究发现,红锈病、叶斑病、灰枯病和褐枯病是北阿坎德邦Bageshwar地区蚕茧的常见病,影响了蚕茧的产量和产茧的质量和数量。

Salt stress is one of the major global problem rendering vast area of land unsuitable for cultivation. Attempts are therefore directed to screen for salt-tolerant plants for the reclamation of the waste-land. The present study was an attempt to search for the salt tolerance potential of an important endangered medicinal plant Psoralea corylifolia, which is the commercial source of psoralen. Psoralea seeds grown on different concentrations of NaCl exhibited variation in percent germination; however, 25 mM NaCl proved better than control and exhibited maximum percent germination with high shoot and root length. Chlorophyll a, b and a+b decreased on higher concentrations of NaCl. Protein content decreased from 50–100 mM NaCl and then again there was an increase from 110 mM NaCl. Psoralen content exhibited variation in salt-stressed seedlings and maximum psoralen was observed in 25 mM NaCl concentration.
盐胁迫是导致大片土地不适宜耕种的主要全球性问题之一。因此,要努力筛选耐盐植物,以便开垦荒地。本研究旨在探索一种重要的濒危药用植物补骨脂的耐盐潜力,补骨脂素是补骨脂素的商业来源。不同浓度NaCl处理的补骨脂种子萌发率存在差异;但25 mM NaCl处理的发芽率高于对照,且芽长和根长均较高。叶绿素a、b和a+b随NaCl浓度升高而降低。蛋白质含量从50 ~ 100 mM NaCl开始下降,从110 mM NaCl开始上升。补骨脂素含量在盐胁迫下表现出差异,在25 mM NaCl浓度下补骨脂素含量最高。

Medicinal plants are considered to be an important source of life-saving drugs for majority of the world's population. Recently there has been an increasing interest in the study of medicinal plants and their traditional use in primary healthcare. An ever-increasing demand of uniform medicinal plants and plant based medicines warrants their cloning through plant tissue culture (PTC) strategy. The biotechnological approaches are important to select, multiply and conserve the critical genotypes of medicinal plants. PTC techniques offer an integrated approach for the production of standardized quality phytopharmaceuticals through the mass production of consistent plant material. A variety of medicinal plants have been regenerated through in vitro techniques using various parts. This review is an attempt to highlight the current strategies available for in vitro propagation of medicinally important Cassia species. The genus Cassia is one of the most important genus of subfamily Caesalpinaceae (family Fabaceae), mostly distributed in the tropics and subtropics. It is comprised of about 600 species, most of them having medicinal values and used to cure a broad range of diseases, such as anaemia, bronchitis, cholera, eczema, jaundice, leprosy, liver diseases, scabies, splenic enlargement, typhoid, rheumatism, eye and skin diseases, cough, insomnia, headache, ophthalmia, constipation, hypertension and many more. Cassia spp. also possess anticancer, antidiabetic, antidiuretic, antihelminthic, anti-inflammatory, antigungal and purgative properties. The available literature on in vitro micropropagation of Cassia spp described the differential response to cytokinin and auxin treatment in the media for effective shoot regeneration and plantlet propagation. It was also found that the explants type played a specific role in morphogenesis and multiplication.
药用植物被认为是世界上大多数人口救命药物的重要来源。最近,人们对药用植物及其在初级保健中的传统用途的研究越来越感兴趣。对统一药用植物和植物基药物的需求日益增长,需要通过植物组织培养(PTC)策略进行克隆。生物技术手段对药用植物关键基因型的选择、繁殖和保护具有重要意义。PTC技术通过大量生产一致的植物材料,为生产标准化的高质量植物药提供了一种综合方法。各种药用植物已经通过体外再生技术利用不同的部分。本文综述了目前重要药用决明子的体外繁殖策略。决明子属是豆科决明子亚科最重要的属之一,主要分布在热带和亚热带地区。它由大约600个品种组成,其中大部分具有药用价值,用于治疗各种疾病,如贫血、支气管炎、霍乱、湿疹、黄疸、麻风病、肝病、疥疮、脾肿大、伤寒、风湿病、眼睛和皮肤疾病、咳嗽、失眠、头痛、眼炎、便秘、高血压等等。决明子还具有抗癌、抗糖尿病、抗利尿、抗寄生虫、抗炎、抗牙垢和通便的特性。现有的关于决明子离体微繁的文献描述了细胞分裂素和生长素处理对决明子离体微繁苗的差异反应,以实现有效的苗再生和苗繁殖。还发现外植体类型在形态发生和增殖中起着特定的作用。
