College, Sidhi, Madhya Pradesh, India Abstract Coleus rotundifolius L. belonging to the family Lamiaceae commonly known as Patharchur in Hindi, It is a large succulent aromatic perennial herb. The leaves of this plant have been used in malarial fever, hepatopathy, renal and vesicle calculi, cough, chronic asthma, hiccough, bronchitis, anthelmintic, colic and convulsions. This paper deals with the pharmacognostical evaluation of leaves, stems and roots of Coleus rotundifolius by using different parameters. Keywords: Coleus rotundifolius, Phytoconsituents, carbohydrates, leaf extract, traditional Introduction Preliminary phytochemical screening It is a large succulent aromatic perennial herb. Much Preliminary phytochemical screening was carried out by branched, fleshy highly aromatic pubescent herb with using standard procedure described by Kokate et al. (1986) distinctive smelling leaves. The plant is distributed through [11]. Total phenol content of the extracts was determined by out India, cultivated in the gardens. It is a folkloric using the Folin-Ciocalteu method (Sadasivam snd Manikam, medicinal plant used to treat malarial fever, hepatopathy, 1992) [12]. Total flavonoid content was determined as (Kirtikar and Basu, 1971) [1] renal and vesical calculi, described by Singleton & Rossi (1965) [13]. The amount of cough, chronic asthma, (Nadkarni, 1996) [2] hiccough, total alkaloids and total saponins was determined according bronchitis, helminthiasis, colic, convulsions and epilepsy to method given by Rajpal (2002) [14]. (Gil-Otaiza, 1997) [3]. It is used to treat colds and cough as well as arthritic inflammations (Gomez-Rodriguez, 1982) [4]. Results and discussions Its insect repellent properties have been tested (Kathiresan, Determination of physicochemical parameters 2000) [5] and another member of the Coleus genus. Studies Various physicochemical parameters were evaluated for the performed in India demonstrated the “fungistatic” properties leaf, stem and root parts as per WHO guidelines. Significant of the essential oil of this plant (Rastogi and Mehrotra, amount of acid insoluble ash had been detected which 1979) [6]. The Phytochemical study reveals the presence of indicates presence of various silicacious substances. various flavonoids like quercetin, apigenin, luteolin, Cellulosic substances also contributed significantly in total salvigenin, genkwanin and volatile oils in the leaves ash as indicated by water soluble ash. (Buznego and Perez-Saad, 1999) [7]. Ethanolic and aqueous The plant contains fewer amounts of non-polar substances leaf extracts of the plant has been found possess significant in comparison to polar substances, as extractive value diuretic activity (Patel et al. 2010) [8]. The plant is also increases with the increase in the polarity of solvents. known to contain the constituents responsible for However, alcoholic and aqueous extractives showed cytotoxicity and anti bacterial activity (da Costa et al. 2010) significant yields. Significant amount of moisture had been [9]. also found in air-dried materials (Table-1 & Fig 1). Material and methods Plant material Coleus rotundifolius was collected from the surrounding Sidhi city, Madhya Pradesh and authenticated by Prof. M. Salim, Dept. of Botany, S.G.S. Govt. P.G. College, Sidhi. The collected plants are washed thoroughly with water, all the three parts i.e. leaves, stems and roots were separated and dried in shade at room temperature and powdered using hand mill to make a coarse powder. Then they are stored in well closed light resistant container until further use. Fig 1: Figics analysis of Physicochemical parameters of leaves stem and root parts.
