Abstract A high performance liquid chromatographic method was developed to determine all types of -carboline alkaloids in medicinal and edible plants. They are hepatotoxic, mutagenic and carcinogenic and pose a threat to human health and safety. Well-known alkaloids include morphine, strychnine, quinine, ephedrine, and nicotine. Plants containing alkaloids were used during the middle ages for various human and animal diseases. Majority of alkaloids function in the defense of plants against herbivores and pathogens and exploited as pharmaceuticals, stimulants, narcotics due to their potent biological activities. the alkaloid profile of a US-grownM. In the current study, Catharanthus roseus is considered as medicinal plants b In comparison between standard harmine and. The alkaloids are mostly colourless, crystalline and non-volatile solids. Keywords: Phytochemicals, Decoction, Infusion, HPLC, HPTLC, OPLC, NMR, X-Ray crystallography. The alkaloids, including internal standards, were purified from plant homogenates by serial extractions after reacting with fluorescamine.

The original volume was reduced to half and the mixture was cooled on ice for 15minutes where the flavonoids .
Pigment and unsaturated materials are removed by shaking with chloroform or other organic solvents. Hence, this study focused on both qualitative and quantitative determination of the phytochemicals, micronutrients and proximate constituents. %Alkaloids content = [20ml taken of N/50H 2 SO 4] x 0.005787 x 100/10.
Quantification of total content of alkaloids 1 mg of the plant extract was dissolved in dimethylsulphoxide ) and added 1ml of 2N HCl and filtered. It was estimated that about 90% of the species of marine plant are algae and about 50% of the global photosynthesis is contributed from algae . Phytochemical characterization of plants is an important task in medicinal botany and drug discovery. On the other hand, accurate methods must be mastered perfectly or the results could be even worse than with the simple methods. Figure 2: Quantitative determination of Secondary metabolites from Lanatana camara leaves Alkaloids are a special group of secondary nitrogenous compounds. Quantitative Determination of Alkaloids 7. The HPLC-ESI/MS/MS quantitation revealed significant alkaloid levels, in particular for bufotenine and 5-methoxy-bufotenine. Test for phenols: To 2.0ml of the plant extract 5% ferric chloride was added and observed for the alkaloids, flavonoids, phenolics, steroids, tannins, saponins etc. Determination of Alkaloids Quantitative determination of alkaloid was according to the methodology by Harborne [ 2 ]. One gram of the sample was weighed into a 250 ml beaker and 200 ml of 10% acetic acid in ethanol was added and its covered and allowed to stand for 4 h. It was filtered and the extract was concentrated on present in the plant extracts. 26, n 3, p . After compound identification the next typical step is . The proposed technique is highly reproducible and adequately reflects the content of alkaloids in the roots and preparations of Vinca herbacea, which . Quantitative estimation of total alkaloid, tannin and phenol revealed that there is significant presence of tannin and phenol in the plant extract while alkaloid are present in lesser amount. The taxonomical origin (plant families rich in alkaloids.) This work suggests that there are several M. speciosa chemotypes. THE common methods of isolation of alkaloids in relatively pure forms from plant materials now available involve extraction by solvent partition and/or column chromatography. Both methods are described in the Chinese Pharmacopoeia 2015 ( Shen et al., 2020 ). alkaloids of plant origin include caffeine, nicotine, cocaine, and the synthetic O, O-acetylated morphine derivative heroin  Based on the strong evidence of biological activities of plant alkaloids, the study was focused on determination of total alkaloid contents of selected Justicia species. LC-MS/MS quantitative determination of Tetrapterys mucronata alkaloids, a plant occasionally used in ayahuasca preparation. Non-aqueous titration: This method is suitable for determination of weak bases e.g. The presence of alkaloids is indicated by a white creamy precipitate .
