Volume 7, Issue 10, 2018 Page No: 685 International Journal of Scientific Research and Review ISSN NO: 2279-543X INTRODUCTION The application of plants as medicines dates back to prehistoric period. Plants are more effective healers because they endorse the repair mechanisms in the natural way. Medicinal plants provide about 80% drugs world wide. Cuscuta reflexa Roxb. (Family: Convolvulaceae) is usually known as “Akashabela, Amarabela, dodder plant, devil’s hair etc. It is a perennial, parasitic, rootless, chlorophyll free parasite fully depends on a host plant for support and food supply. It is usually found in India and Ceylon upto an altitude of 2348m, also found in plains of Nepal, Malaysia, Thailand and Afghanistan etc [1]. In India, the plant is traditionally used for various medicinal purposes. The seeds are emmenagogue, sedative, diuretic, useful in disease of the spleen and liver, chronic fevers and hiccough, also purify the blood and clean the bowel [3]. Its stem is used as a purgative. Juice of the plant was given in combination with other purgative decoction [4] and also inhaled for treating jaundice, paste of the plant is applied in gout, rheumatism and for relieving headache [5]. Cuscuta reflexa is investigated for Antioxidant, Antimicrobial, Antidiabetic, Antitumor, Anti-inflammatory, Antipyretic, Antiviral, Antihypertensive, Hair growth promoting and Spasmolytic activities etc. It contains Glycosides, Flavanoids, Alkaloids, Cuscutin, Cuscutalin and Amarvel etc. It also indicates the presence of astragallin [6], myricetin, benzopyrones [7]. A new compound reflexin [5- hyroxy – 7 methoxy – 6 (2, 3 epoxy-3 methyl butyl)-Flavanone] has been isolated [8].This review article presents a critique of the literature on pharmacognosy, phytochemistry, traditional and biological medicinal uses of Cuscuta reflexa Roxb.

Volume 7, Issue 10, 2018 Page No: 687 International Journal of Scientific Research and Review ISSN NO: 2279-543X BOTANICAL DESCRIPTION: Cuscuta reflexa is perennial parasitic herb. Stems are filiform twining, much–branched, often forming a tangled mass. Flowers solitary or in shortly pedunculate cyme, pedicles short, bracts ovate, 1.25mm long divided rather less than half way down, lobes deltoid ovate subobtuse often with a tubercular keel on the back. Corolla 2.5mm long, lobes about equalling the tubes, ovate- oblong, subobtuse, scales at the base of the filaments fimbriate. Filaments 0.8mm long style 2, distinct, 1mm long capsules hardly 2.5mm diameter, globose, hyaline, divided into 2 lobes by a deep furrow on top, seeds 1.6mm long usually four.Seeds 2-4, large, black and glabrous [13, 14]. MORPHOLOGY: Macroscopic: The drug constitute a dense tuft of intertwine, much branched, very thin almost thread like light brown stem mass, Portions of host plant with the stem twined on it are also present. Stem is coarse to touch, glabrous, bears no leaves and breaks very easily.At places, fruits are borne on stem, 5-8 in number in a single cyme and light brown in colour. It has no odour but has a slightly bitter taste. Fruit is an indehicent capsule, 3-5mm in diameter globes in shape borne on pedicle. It has persistant calyx and almost transparent wall through which dark brown seeds are clearly visible. At the top it has a small pore while some bear reminiscent of style, still attached. It has four seeds, these are three sided, the one along its length is convex on one side. One side is slightly concave while the third is almost plane. The seeds are smooth, 1 to 1.5mm in diameter while the length is 1.5mm to 2mm. It has no odour but bitter in taste [13,14,15]. Microscopic: Transverse section of the stem shows a circular but a wavy outline. The outermost layer is a single row of epidermis, lined externally by a cuticle. Epidermal cells are not uniform in shape. A 4-6 layered zone of cortex which has thin walled cells of various sizes and shapes. Endodermal layer is non distinguishable. The cells towards the innermost layer of cortex become smaller and surround the vascular bundles, forming a sheath. Vascular bundles are collateral, 5-7 in number and not situated on the same radious. The xylem is not well developed and consists of thin vessels; few in number, in a single group. Phloem are scarcely distinguishable except that some large cells with small companion cells are seen outside the metaxylem.A large zone of pith consisting of thin walled cells present in the centre. The pith cells have a brown colour pigment. Some prismatic crystals of calcium oxalate are visible in isolated cells [13,14,16].

Tate Abstract—Cuscuta (dodders, Convolvulaceae) is one of the largest and most economically important lineages of parasitic plants. The genus has a sub-cosmopolitan distribution with more than 75% of the species diversifying in the New World. The last monograph, published by Truman George Yuncker in 1932, provided a solid species-level taxonomic foundation. However, as revealed by recent phylogenetic studies, its infrageneric classification has been in great need of a taxonomic reappraisal, mainly because the morphological characters used in the previous classifications have been greatly affected by convergent evolution. Several recent phylogenetic and character evolution studies with broad sampling, as well as species-level revisions, have illustrated the deficiencies of previous classifications and provided an explicit and robust phylogenetic framework. Here we propose a new phylogenetic classification that places all 194 currently accepted species of Cuscuta into four subgenera and 18 sections. Sections have a strong morphological and biogeographical predictive value and include from one to 31 species. Thirteen section names are new or applied for the first time at the sectional rank: Babylonicae (Yunck.) M.

E-mail : [email protected],[email protected] Abstract Cuscuta reflexa is an extensive leafless, parasitic climber belong to the morning glory family Convolvulaceae. It is yellowish green and thread like twinning herb and tangled mass covering the host plant. It occurs throughout the India. It has no chlorophyll and cannot make its own food by photosynthesis. The plant is attached to various trees, shrubs, herbs and affect commercially valuable crops. Plant is completely dependent on host plant for their food and nutrition. C. reflexa varies in the colours of the flowers produced from white to pink. Seeds are produced in the large quantities. Seeds of C. reflexa can survive in the soil for many years in the search of the appropriate host. It has 100-170 species. C. reflexa has various type of phytoconstituents including chemicals, flavonoids, carotenoids, the esters of higher aliphatic alcohol with the saturated fatty acids and carbon atoms. It is a parasite plant it sucks nutrient from the host plant for its growth and development hence its phytoconstituent also depends on the host plant. C. reflexa has been used from ancient times for various purposes viz. as a purgative in the treatment of liver disorder, cough, itching, constipation, flutance, body pain, jaundice, gout, rheumatism , urination disorders muscles pain, impotence, premature ejaculation, sperm leakage, ringing in the ear, lower back pain, sore knees, leucorrhea, dry eyes, blurred vision and tired eyes.

  • Managing Cuscuta Gronovii (Swamp Dodder) in Cranberry Requires an Integrated Approach
    Sustainability 2010, 2, 660-683; doi:10.3390/su2020660 OPEN ACCESS sustainability ISSN 2071-1050 www.mdpi.com/journal/sustainability Review Managing Cuscuta gronovii (Swamp Dodder) in Cranberry Requires an Integrated Approach Hilary A. Sandler Cranberry Station, University of Massachusetts-Amherst, P.O. Box 569, East Wareham, MA 02538, USA; E-Mail: [email protected]; Tel.: +1-508-285-2212 Ext. 21; Fax: +1-508-295-6387. Received: 11 December 2009 / Accepted: 5 February 2010 / Published: 24 February 2010 Abstract: Dodders (Cuscuta spp.) are parasitic plants that threaten the sustainability of many crops. Because this parasite is very adept and successful from biological and ecological perspectives, a single control strategy is unlikely to provide sufficient economic control. Dodder (C. gronovii) is a particularly serious pest in commercial cranberry (Vaccinium macrocarpon) production. Multiple viable strategies must be integrated and tailored into a weed management plan to provide acceptable control. The key to sustainable management of this serious pest will require a combination of chemical and cultural approaches, supported by understanding the complicated nature of dodder biology. Research from small fruit production systems like cranberry into the biology of dodder (e.g., germination patterns, host preference, use of plant growth regulators) may provide insights that could ultimately be useful for other crop system management plans. This paper will present the current knowledge base for integrated management of dodder in cranberry as well as highlight relevant research from other crops and potential topics for future research. Keywords: parasitic plants; Cuscuta; weed management; IPM; Vaccinium macrocarpon 1. Introduction Dodders are obligate parasitic plants consisting of yellow twining stems that produce small clusters of white flowers [1].

Abstract The parasitic flowering plant genus Cuscuta (dodder) attacks shoots of all plants within its range but the outcome of this attack depends on the response pattern of the potential hosts. Compatible (or susceptible) hosts cannot prevent that their tissue is being penetrated and their vascular vessels are being tapped into, while incompatible (or resistant) hosts can stop the infection at an early stage, preventing the penetration of the haustoria and starving the parasite to death. Susceptibility and resistance can occur even in closely related species, offering the possibility to identify the responsible genes using molecular genetic tools. In this work, such a ménage à trois, consisting of the giant dodder C. reflexa, the resistant host Solanum lycopersicum M82 (processing tomato) and the susceptible host Solanum pennellii (wild desert tomato), was characterized.
