Histopathological studies of kidney structure showed normal structural features suggesting the
preserved renal integrity of MECO treated rats. This study has shown the diversity in toxicity as well as the chemical constituents of the root parts of C. orchioides in relation to the extraction solvent. The No Observed Adverse Effect Level (NOAEL) of C. orchioides was estimated to be greater than 800 mg/kg/day. This study provides the basis for further study on the detailed toxic and pharmacological effects of the extracts of aerial parts of C. orchioides and their active component(s). All authors have none to declare. The authors are thankful to Shri C. Srinivasa Baba, Shri G. Brahmaiah and Shri M.M. Kondaiah, Management of Gokula Krishna College of Pharmacy, Sullurpet, SPSR Nellore Dist, A.P., India for providing the laboratory facilities during the course of research studies. “
“The use of plants, plant extracts or pure selleckchem compounds isolated from natural products to treat diseases is a therapeutic modality, which has stood the test of time even if much of the science behind such therapy is still in its infancy. There has been a resurgence of scientific interest
in medicinal plants during the past 20 years, being rekindled by the worldwide importance of medicinal plants and crude drugs in traditional medicine. Modern allopathic usually aims to develop a patentable single compound or a “magnetic bullet” to treat specific conditions. Traditional medicine often aims to restore balance by using chemically complex plants, or by mixing together several different AC220 plants in order to maximize a synergistic effect or to improve the likelihood of an interaction with a relevant molecular target. The curative properties of medicinal plants are mainly due to the presence
of various complex secondary metabolites viz. flavonoids, these glycosides, alkaloids, saponins, tannins, terpenoids etc. Hence the present study was undertaken to isolate a novel structure from the fruit pulp of Feronia limonia L. The air dried, powdered and defatted material of F. limonia L. fruits were extracted with rectified spirit extract was concentrated under reduced pressure to get a brown viscous mass, which was successively partitioned with petroleum ether, benzene, chloroform, ethyl acetate, acetone and methanol respectively. The ethyl acetate soluble part was concentrated under reduced pressure to get a brown syrupy mass, which when examined by TLC on silica-gel G using chloroform:methanol:water (8:5:3) and iodine vapors as visualizing agent displayed two spots. As such it was subjected to column chromatography on silica-gel – Emerk and eluted by with acetone:methanol in various proportions. On removal of the solvent of fraction (7:4), light yellow needles (RS-2) were separated out. RS-2 was found to be homogenous on TLC (MeOH:H2O:ACOH, 4:6:1).
