Abstract Sphaeranthus indicus is a well-known plant used in the Indian system of medicine. The plant is widely distributed throughout the plains and wet-lands of India, Sri Lanka and Australia. Folklore medicine claims its use in epileptic convulsion, mental illness, hemicranias, as a general tonic, deobstruent, aphrodisiac etc. Various biologically active compounds have been isolated from S. indicus. Sphaeranthus Linn. is a genus of plants belonging to family Asteraceae. Most of the species of this genus are aromatic herbs occurring as weed in paddy fields, in temperate regions. S. indicus is the only plant of this genus which has been widely explored pharmacognostically, phytochemically and pharmacologically. Other important species of this genus are S. africans Linn., S. alatus, S. amaranthoides Burm. f., S. indicus Linn., S. suaveolens and S. zeylanicus. The review article contains ethnopharmacology, morphology, microscopy, physico-chemical parameters, Phytochemistry and pharmacological updates of the genus Sphaeranthus which may be beneficial for the researchers, academicians, medical practitioners working in the field of natural products. Volume 5, Issue 7, July 2018 57 http://cikitusi.com/ CIKITUSI JOURNAL FOR MULTIDISCIPLINARY RESEARCH ISSN NO: 0975-6876 1. Ethnopharmacology S. indicus (synonym S. hirtus Willd) is an aromatic, much branched herb, 30-60 cm high found abundantly in damp and shady places in Sri Lanka, Africa, Australia, Ceylon, Malay and China. In India it is found in plains all over the country, ascending to an altitude of 1,500 m in the hills. It is an Ayurvedic and Unani drug commonly known as Gul-E-Mundi, Mundi, Gorakhmundi, Alambusta, Sembung delan, Kottakkarantai, Sravani, East Indian globe. The plant is cultivated throughout India in rainy season (Rosenblatt et al., 1976; Kirtikar and Basu, 1998, Chatterjee and Chanderprakashi, 2003; API, 2007). It is widely used in Ayurvedic system for the treatment of mental disorders, diabetes, jaundice, tuberculosis, spleen disease, anaemia, leucoderma, vagina pain, asthma, piles and leprosy. The plant has been used traditionally as tonic, laxative, digestive, anthelmintic, in bronchitis and elephantiasis. Roots are bitter, acrid, sweet, thermogenic, diuretic, expectorant, febrifuge and stomachic, use in diabetes, hernia, haemorrhoids, helminthiasis and dyspepsia. Root oil is used in scrofula. Leaf has been used in skin diseases and as a nervine tonic. (Kirtikar and Basu, 1998; Chopra et al., 1956). Flowers are used as alterative, depurative, cooling and tonic. These are also used as blood purifier in skin diseases and employed internally as well as externally in chronic skin ulcerations, irritation, scabies and ringworms. Powdered bark mixed with whey is a valuable remedy for piles. Hindus used to make a kind of confection of the young plant by rubbing it up with clarified butter, flour and sugar. A portion of this taken daily is said to be a good tonic and prevents the hair turning white or falling off (Kirtikar and Basu, 1998). S. amaranthoides has been traditionally used for the treatment of eczema, blood disorder, stomach worms, filaria, fever, skin diseases and as a remover of kapha, vata and piles (Kirtikar & Basu, 1998). Volume 5, Issue 7, July 2018 58 http://cikitusi.com/ CIKITUSI JOURNAL FOR MULTIDISCIPLINARY RESEARCH ISSN NO: 0975-6876 S. zeylanicus leaves have been traditionally used as astringent, diuretic, stomachic, antispasmodic, anti-syphilitic and anti-emollient (Hasani et al., 2009). 2. Morphology, microscopy and physico-chemical parameters Bafna et al. (2006) reported the morphology of stem and flower of S. indicus. Flower morphology is also documented in Ayurevdic Pharmacopoeia of India (API, 2007). Microscopy of different parts of S. indicus and physico-chemical parameters viz. ash values, extractive values, foreign organic matter, etc. are very well documented (Vikani et al., 2008; Mallya et al., 2014; Gowri et al., 2015; API, 2007). Sphaeranthus indicus is an annual herb with sessile, decurrent, obovate, bristly serrate, downy, glutinous leaves and globular heads of purple flowers. The stem is greenish in colour; roots are brown externally and internally light brown, tuberous with 10-15 cm in length and 0.1-0.4 cm in diameter with longitudinal striations and transverse scars seen at regular intervals (I.K. Makhija et al., 2011).

  • 1 Sistemática Filogenética De Pterocaulon E Wunderlichia
    Sistemática filogenética de Pterocaulon e Wunderlichia (Asteraceae) Pesquisador responsável: Dr. João Semir Universidade Estadual de Campinas Resumo A grande variabilidade morfológica que as plantas apresentam permite a caracterização e o reconhecimento das espécies, constituindo assim, a base da taxonomia. O número de caracteres utilizados para o reconhecimento das espécies aumentou muito ao longo da história da classificação dos organismos e, nas últimas décadas este acréscimo foi ainda maior devido aos avanços oriundos de estudos moleculares. Atualmente técnicas utilizando dados moleculares associados aos dados morfológicos são excelentes fontes de informação para os estudos de evolução e reconstrução filogenética. Asteraceae é a maior família entre as Angiospermas, possui cerca de 24.000 espécies distribuídas em 1.600 gêneros dem distribuição cosmopolita. Nos Neotrópicos a diversidade da família é de aproximadamente 580 gêneros e 8.040 espécies. Para o Brasil são referidas 1.960 espécies distribuídas em 288 gêneros, representando a terceira maior família de plantas com flores para o Brasil, colocando-o como um centro de diversidade das Asteraceae. O presente projeto faz parte dos estudos para o conhecimento da diversidade das Asteraceae brasileiras e tem como objetivo reconstruir hipóteses filogenéticas dos gêneros Pterocaulon e Wunderlichia, com base em dados moleculares, permitindo o estudo e interpretação da evolução de caracteres morfológicos importantes para a circunscrição desses gêneros. Para este propósito, além dos dados moleculares, serão utilizadas ferramentas, como o estudo taxonômico e cromossômico. Os resultados serão apresentados em forma de artigos, publicados em periódicos e também divulgados em reuniões científicas. O desenvolvimento deste projeto é importante, pois será realizado por meio de parcerias com pesquisadores de outras áreas da botânica sendo possível ampliar o conhecimento dos táxons em análise, contribuindo para melhorar a compreensão acerca da diversidade, biologia e conservação dos mesmos.

  • Numerical Taxonomic Study of Some Tribes of Compositae (Subfamily Asteroideae) from Egypt
    Pak. J. Bot., 43(1): 171-180, 2011. NUMERICAL TAXONOMIC STUDY OF SOME TRIBES OF COMPOSITAE (SUBFAMILY ASTEROIDEAE) FROM EGYPT A. K. OSMAN Department of Botany, Faculty of Science, South Valley University, Qena, Egypt. Abstract A systematic study of 25 taxa belonging to 12 genera of tribes Gnaphalieae, Helenieae, Plucheeae and Senecioneae of Compositae from Egypt was conducted by means of numerical analysis based on 19 main pollen grains characters. On the basis of UPGMA (Unpaired Group Method off Averaging) clustering and PCO (Principal Component Analysis), two main groups and five subgroups are recognized. Introduction The Compositae (Asteraceae) is the largest family of plants, comprises of 1590 genera and around 23,600 known species arranged in 3 subfamilies, Asteroideae, Cichorioideae and Barnadesioideae and 17 tribes (Bremer, 1994; Bremer & Jansen 1992). Tribe Gnaphalieae is one of the largest in the family, with more than 180 genera and 2000 species. Most Gnaphalieae are characterized by a two-layered pollen sexine with an outer baculae and an inner perforated layer. The Gnaphalieae are subdivided into five subtribes (Anderberg, 1991a). In subtribe Gnaphaliinae, the two largest genera are Helichrysum and Gnaphalium, with hundreds of species and with many closely related segregate genera. Classification problems within the tribe are dominated by the difficulties in generic delimitation of Helichrysum and Gnaphalium. The Helenieae comprise a little more than 800 species in 110 genera, are often herbs. Some species have become naturalized as weeds in most parts of the world, eg., Tagetes minuta L. (Bierner, 1989).
