CHAPTER-I INTRODUCTION Medicinal and aromatic plants have been used since ancient times in the traditional practices for health care. it is well known that plants are an important source for a variety of bioactive compounds for a variety of purposes including pharmacy ,medicine and industry, According to WHO report nearly 70-80% of the world population relies on traditional medicine largely which are produces plant based for primary health care needs. the annual international market of herbal product is estimated to be US$20 million. with increasing popular demand for medicinal plants both in india and internationally. Human being had depended only on natural sources to a larger extent particularly on plants of his vicinity for getting rid of these ailments. Besides for his other needs Several potent medicinal plants have seen the light of the day due to his continous usage of the effective drugs, Some of these plants have attracted the herbalist who have put these plants in to use for centuries together and included the more potent one in the materia medica of their region. Scientific study of folk medicine is very essential because the efficacy of a drug depends upon various factors such as genuinity, preparation administration and dosage of drugs. Pharmacognosy is the study of crude drugs obtained from plants, animals and mineral kingdom and their constituents. Even though science of Pharmacognosy is practiced since a very early period. 1 The term Pharmacognosy was first used by C.A. SEYDLER, a German Scientist, in 1865 in his book Analecta Pharmacognostica. It is derived from two Latin words Pharmakon, “a drug” and gignosco, “to acquire knowledge of”. It means knowledge or science of drugs.1,2,3,4,5 NEUROPATHY A classical term for any disorders affecting any segment of the nervous system. NEUROPATHIC PAIN Neuropathy is a collection of disorders that occurs when nerves of the peripheral nervous system (the part of the nervous system outside of the brain and spinal cord) are damaged. The condition is generally referred to as peripheral neuropathy, and it is most commonly due to damage of nerve axons. Neuropathy usually causes pain and numbness in the hands and feet. It can result from traumatic injuries, infections,

    Appendix Color Plates of Solanales Species The first half of the color plates (Plates 1–8) shows a selection of phytochemically prominent solanaceous species, the second half (Plates 9–16) a selection of convol- vulaceous counterparts. The scientific name of the species in bold (for authorities see text and tables) may be followed (in brackets) by a frequently used though invalid synonym and/or a common name if existent. The next information refers to the habitus, origin/natural distribution, and – if applicable – cultivation. If more than one photograph is shown for a certain species there will be explanations for each of them. Finally, section numbers of the phytochemical Chapters 3–8 are given, where the respective species are discussed. The individually combined occurrence of sec- ondary metabolites from different structural classes characterizes every species. However, it has to be remembered that a small number of citations does not neces- sarily indicate a poorer secondary metabolism in a respective species compared with others; this may just be due to less studies being carried out.

  • Annotated Checklist of Thai Convolvulaceae Taxonomic Research for the Account of the Convolvulaceae of Thailand Has Been Carried
    THAI FOR. BULL. (BOT.) 33: 171–184. 2005. Annotated checklist of Thai Convolvulaceae GEORGE STAPLES*, BUSBUN NA SONGKHLA**, CHUMPOL KHUNWASI** & PAWEENA TRAIPERM** ABSTRACT. An annotated checklist to the Convolvulaceae of Thailand is presented. The account covers 24 genera, 127 species and four infraspecific taxa. The present checklist includes the accepted name for each taxon plus selected synonyms and misapplied names that have been used in late 20th century taxonomic literature about the Thai flora. Taxa known to be cultivated in Thailand, but not yet escaped or naturalised, are included in the checklist and indicated as such. Taxonomic research for the account of the Convolvulaceae of Thailand has been carried on independently by the first author and a team from Chulalongkorn University. A significant number of changes have come to light, relative to the last comprehensive list of taxa for the family (Kerr 1951, 1954). These include nomenclatural and taxonomic changes as well as new distribution records for Thailand. During a visit to Bangkok in December 2002 the authors met and decided to combine their efforts to produce a new comprehensive checklist of names for Thai Convolvulaceae as a precursor to the full account of the family now in preparation. It is hoped that having an up-to-date checklist of names available now will be useful to collectors, researchers, and students during the time that the full flora account is being written. The present checklist includes the accepted name for each taxon plus selected synonyms and misapplied names that have been used in late zoth century taxonomic literature about the Thai flora.

  • Noteworthy Distributions and Additions in Southwestern Convolvulaceae
    NOTEWORTHY DISTRIBUTIONS AND ADDITIONS IN SOUTHWESTERN CONVOLVULACEAE Daniel F. Austin Arizona-Sonora Desert Museum Tucson, AZ 85734 [email protected] ABSTRACT Since 1998 when the Convolvulaceae was published for the Vascular Plants of Arizona, Calystegia sepium ssp. angulata Brummitt and Convolvulus simuans L. M. Perry have been added to the flora and another species, Jacquemontia agrestis (Choisy) Meisner, has been located that had not been found since 1945. Descriptions, keys, and discussions of these are given to place them in the flora. Additionally, these and Dichondra argentea Willdenow, D. brachypoda Wooton & Standley, D. sericea Swartz, Ipomoea aristolochiifolia (Kunth) G. Don, I. cardiophylla A. Gray, I. ×leucantha Jacquin, and I. thurberi A. Gray, with new noteworthy distributions records in the region, are discussed and mapped. All taxa documented by recent collections are illustrated to facilitate identification. DISTRIBUTION PATTERNS AND ADDITIONS TO THE ARIZONA FLORA Three notable disjunct records have been discovered within Arizona since the treatment of the Convolvulaceae was published for the state (Austin 1998a), Calystegia sepium ssp. angulata Brummitt, Convolvulus simulans L.M. Perry and Jacquemontia agrestis (Choisy) Meisner. Additionally, Ipomoea aristolochiifolia (Kunth) G. Don has been found just south of the border in Mexico. All of these are significant disjunctions in the family, but there are others that have been documented for years and little discussed. Although these are not the only disjunctions within the Convolvulaceae in the region, they are representative of floristic patterns in this and other families. The following discussion updates the known status of the Convolvulaceae in Arizona and compares several species to the floras from which they were derived.

THE EXTRAFLORAL NECTARIES OF IPOMOEA LEPTOPHYLLA (CONVOLVULACEAE)l KATHLEEN H. KEELER School of Life Sciences, University of Nebraska, Lincoln, Nebraska 68588 ABSTRACT Ipomoea leptophylla Torr. (Convolvulaceae) is a sprawling dry-site morning glory with two types of extrafloral nectaries: foliar nectaries and nectaries on the outside of the sepals. Both are shown to greatly increase insect visitation to the plant. Ants visiting sepal-surface nectaries significantly decrease flower damage caused by grasshoppers and seed losses caused by bruchids. These results are similar to those for I. carnea and other plants whose extrafloral nectary-ant interactions have been studied, but differ in detail. This is the first demonstration of antiherbivore defense of a prairie plant by nectary visitors.

TIFAC CORE in Herbal Drugs, JSS College of Pharmacy, Ootacamund - 643 001, The Nilgiris, Tamilnadu, India. 2. Department of Pharmaceutical Chemistry, JSS College of Pharmacy, Ootacamund - 643 001, The Nilgiris, Tamilnadu, India. Abstract Objective: To evaluate the free radical scavenging activity of Ipomoea obscura (L.) whole plant belonging to the family Convolvulaceae. Methods: Three successive whole plant extracts (petroleum ether, methanol and water) of Ipomoea obscura were prepared and the total phenolic content was estimated. The extract were screened for their in vitro antioxidant activity using 2,2’-diphenyl-2-picryl hydrazyl (DPPH), 2,2’-azino-bis (3-ethyl-benzo-thiazoline- 6-sulfonic acid) diammonium salt (ABTS), hydrogen peroxide, nitric oxide, superoxide and hydroxyl radicals by p-nitroso dimethyl aniline (p-NDA) and deoxyribose assays and the IC50 values were calculated. Results: The total phenol content in methanol and water extracts was found to be 18.15 mg/g and 9.12 mg/g, respectively. Among the three extracts tested, the methanol extract showed maximum activity with IC50 values 53.12 ± 0.33, 108.40 ± 2.15, 107.90 ± 1.20 and 424.00 ± 2.90 µg/ml, for ABTS, DPPH, hydrogen peroxide and nitric oxide radical inhibition assays, respectively. The water and petroleum ether extracts showed moderate to low activity compared to methanol extract when tested for ABTS, DPPH, hydrogen peroxide and nitric oxide radical inhibition assays.
