Abstract: The antihepatotoxic efficacy of aqueous extract of Indigofera tinctoria (250, 500 mg/kg body weight) and silymarin were investigated against paracetamol induced liver damage in rats. Paracetamol at the dose of 3 g/kg body weight orally one day only produced liver damage in rats as manifested by the significant rise in serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), - glutamyltranspeptidase (GGT), lactate dehydrogenase (LDH), bilirubin, cholesterol and decrease the protein level compared to control. Treatment of rats with Indigofera tinctoria (250, 500 mg/kg body weight) and silymarin (25 mg/kg body weight) once daily for twenty eight days to paracetamol treated rats shows lowered significantly the afore mentioned clinical parameter where as protein level increased. Further more, liver tissues were processed for histopathologial observation. The extract alone treated rats did not adversely affect the serum biochemical and histopathologial observation. The antihepatotoxic efficacies of the Indigofera tinctoria extracts were reported to be significant.

Abstract: the common name "wild indigo" specifies indigofera anil l., i. suffruticosa mill. (legitimate name) and i. truxillensis kunth (legitimate name) that are very similar due to their external morphology. this work analyzed diagnostic characteristics of seeds and seedlings of these species since such features are widely used in taxonomic approaches within leguminosae. we studied surface features and morpho-anatomy of seeds and cotyledons with scanning electronic microscopy and light microscopy, and described seedling phases. although seedlings are similar, seed characteristics (size, shape, surface ornamentation, shape of the hilum and embryo size) and cotyledon characteristics (shape, trichome ornamentation, organization of spongy parenchyma along central veins and metabolite distribution in the tissues) have diagnostic features for the species. i. anil differs from i. suffruticosa in its larger seeds and acuminate-margined cotyledons. i. truxillensis is recognized by its cylindrical seeds and kidney-shaped cotyledons with large oil drops. we assume that the characteristics examined, plus fruit morphology and foliar anatomy suggest that i. anil, i. suffruticosa and i. truxillensis should not be synonymized.

Abstract: the researches to achieve active principles are long and expensive, and a well standardized plant preparation could be very efficacious. that is why nowadays the use of total extracts has showed, in many instances, a more beneficial effect in human organism than the action of an isolated compound. researches have been conducted to obtain a properly plant drug from indigofera suffruticosa mill (wild indigo) with the required quality. to this end, macro- and micromorphologic descriptions of species were made, a drying study was undertaken, and the numerical indexes were determined, according to the international standards for plant drugs. in the results, it was observed a predominance of flavonoids, coumarins, and tryterpenes, and a chromatographic profile was standardized for flavonoid compounds. it was also confirmed that the optimal period of preservation of the plant drug is 10 months in polypropylene flasks.

Abstract: Aqueous acetone extracts prepared from five Indigofera species of Burkina Faso, namely Indigofera colutea (Burm.) Murril., I. macrocalyx Guilld et Perr., I. nigritana Hook f., I. pulchra willd. and I. tinctoria L., were investigated for their phytochemical composition and their antioxidant activities. Standard methods and TLC were used to screen the phytochemical composition. The total phenolic and flavonoid content of extracts were assessed by Folin-Ciocalteu and AlCl3 methods, respectively. These extracts were also evaluated for their antioxidant potentials using ferric reducing antioxidant power (FRAP), 2,2-diphenyl-l-picrylhydrazyl (DPPH) and 2,2`-azinobis(3-ethylbenzothiazoline-6-sulphonate) (ABTS) assays. Flavonoids, saponins, quinones, sterols/triterpenes and tannins were present in all these species except for I. pulchra where quinones were not found. Gallic acid, caffeic acid, rutin and myricetin in I. colutea; gallic acid, quercitrin, myricetin in I. tinctoria; galangin and myricetin in I. macrocalyx were identified by thin layer chromatography. Among these, I. colutea, I. tinctoria, I. nigritana and I. macrocalyx, which had the highest phenolic content, were also found to possess the best antioxidant activities. The results indicated a good correlation between antioxidant activities and total phenolic content (p<0.05 for FRAP/DPPH and DPPH/ABTS and p<0.01 for FRAP/ABTS). These plants represent promising sources of natural antioxidants and these findings give scientific bases to their ethnopharmacological uses.

Abstract: Folliage of Hairy indigo (Indigofera astragalina) obtained from Sokoto state, Nigeria were studied for their proximate analysis and mineral composition. The proximate composition revealed the presence of moisture (51.000.50% fresh weight), ash (8.170.58% dry weight, DW), crude lipid (5.00.5% DW), crude fibre (2.670.29% DW), crude protein (8.230.11% DW) and carbohydrate (75.940.64%). The energy value was found to be 578.87 kcal/100 g. The minerals composition revealed, potassium (14.550.17 mg/100 g), sodium (0.330.16 mg/100 g), calcium (11.490.34 mg/100 g), magnesium (10.890.32 mg/100 g), phosphorus (0.390.01 mg/100 g), copper (0.020.00 mg/100 g), zinc (0.110.00 mg/100 g), iron (20.953.84 mg/100 g) and manganese (0.430.01 mg/100 g). These results revealed that the leaves of Hairy indigo (Indigofera astragalina) contained essential nutrients which compete favourably well with those of wild edible leaves in literatures.

Pakistan Journal of Biological Sciences , 2006,
Abstract: Palynomorphology of eight species of Indigofera of the tribe Galegeae from Nigeria was investigated with the aid of light microscope. Results from this investigation revealed that these plants were characterised by different pollen grains whose structure differ markedly. The variations in the grains were so obvious that they could be added to other taxonomic information and used in an attempt to determine the relevance of palynomorphology in resolving the confusion in the nomenclature of these taxa. The monoporate, tricolpate and polyporate pollen grain aperture of the eight species of Indigofera are being documented for the first time in these taxa. Similarly the pollen grain shape: circular (round) in I. paniculata, I. stenophylla, I. tinctoria and I. senegalensis, elliptic in I. hirsuta and oval in I. terminalis I. pulchra and I. prieureana are equally distinct and significant in the characterization of these taxa.

Media Peternakan , 2010,
Abstract: A field experiment using Indigofera sp. was conducted at the Farm Research Station of Faculty of Animal Science, Bogor Agricultural University, Darmaga Campus, during 2008-2009. The objectives of this study were to identify the effect of defoliation time on herbage dry-matter production, protein, fiber contents, and in vitro digestibility of different vegetative parts of Indigofera sp. Block randomized design comprising three levels of defoliation time at first regrowth after pruning (38, 68, and 88 days) with 3 replications were used in this experiment. Pruning was done 3 months after transplanted into the experimental plots. First defoliation was conducted after the plant had been pruned. Herbage was derived from different vegetative parts, i.e: leaves of branch base and all parts of shoot tips. The results revealed significant effect of defoliation time on dry matter (DM) production of both branch base and shoot tip herbages. Crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF) and in vitro organic matter digestibility (IVOMD) of branch base were influenced significantly by defoliation time, except crude protein (CP) and in vitro dry matter digestibility (IVDMD). Defoliation time significantly affected CP, CF, NDF, ADF, IVDMD and IVOMD of herbage derived from shoot tips.
