The present study is a first report on the phytochemical analysis of the plant Fibraurea darshani which is endemic to Western Ghats. The plant is a woody dioecious climber belonging to the family Menispermaceae. Preliminary phytochemical screening of methanolic extracts of the stem of F. darshani revealed the presence of secondary metabolites like alkaloids, carbohydrates, anthraquiones, terpenoids, flavonoids, phenolics, sterols etc. A simple and reproducible high performance thin layer chromatography was developed to evaluate the presence of berberine in methanol extract of stem of F. darshani. This method involves separation of compounds by HPTLC on pre-coated silica gel 60F 254 plates with a solvent system of Chloroform: Ethyl acetate: Methanol: Formic acid (4:5:4:0.3) and scanned using densitometric scanner in UV reflectance photo mode at 254 and 366nm. The Rf values (0.97) for berberine in the plant sample and the reference standard were found comparable under UV light at 366nm. The HPTLC method developed was simple, accurate and specific.

Hptlc Method

A simple, sensitive and precise high performance thin layer chromatographic (HPTLC)method has been developed for the estimation of ondansetron (OND) and ranitidine (RAN) in combination. The method was employed on thin layer chromatography (TLC) and aluminium plates were precoated with silica gel 60 F254 as the stationary phase, while the solvent system was methanol. The Rf values were observed to be 0.5 ± 0.02, and 0.3 ± 0.02 for OND and RAN, respectively. The separated spots were densitometrically analyzed in absorbance mode at 299 nm. This method was linear in the range of 25-300 ng/band for OND and 50-600 ng/band for RAN. The limits of detection for OND and RAN were found to be 3.47 and 1.83 ng/band, respectively. The limits of quantification for OND and RAN were found to be 10.53 and 5.55 ng/band, respectively. The proposed method was validated with respect to linearity, accuracy, precision and robustness. The method was successfully applied to the estimation of OND and RAN in combined dosage form.

The Mussaenda frondosa Linn. belonging to the family Rubiaceae, commonly known as Sriparnah in Sanskrit, is a scandent shrub traditionally used in the treatment of cough, bronchitis, fever, inflammation, wounds, ulcers, jaundice, leucoderma and pruritus. Though it is an important plant, till date, no pharmacognostical reports have been available on its leaf. Therefore, the present investigation was undertaken to ascertain the requisite pharmacognostical standards for the standardization of the Mussaenda frondosa leaves. Various investigations like Pharmacognostical studies, preliminary phytochemical screening and High-Performance Thin Layer Chromatography (HPTLC) analysis were carried out, and the salient qualitative parameters were reported. Microscopical evaluation of the leaf revealed the presence of paracytic stomata, microcrystal’s, Idioblast, collenchymas, sand crystals and unicellular unbranched covering Trichomes. The presence of flavonoids, steroids, glycosides, mucilage, saponins and proteins were confirmed through Preliminary phytochemical studies. The HPTLC profile of ethanol extract from M. frondosa L. revealed ten phytoconstituents of Rf value ranging from 0.11 to 0.88. The significant peaks are observed at Rf  values of  0.11, 0.16,  0.23 and 0.81. These findings provide referential information for correct identification and standardization of the Musssaenda frondosa leaves, even in powder form. This information will also be useful to distinguish Mussaenda frondosa from the closely related other species of Mussaenda. The Pharmacognostic and phytochemical profiles reported in this research work for Mussaenda frondosa may play a major role in setting monograph of the plant, which might be helpful in proper identification of the plant.

By conducting the toxicological analysis it is meaningful to determine the analytical system that could identify simultaneously several medicinal preparations quickly and precisely. The purpose of this work was to create and validate the method of thin-layer chromatography that would be suitable to separate the components of antidepressant mixture (amitriptyline hydrochloride, paroxetine hydrochloride, sertraline hydrochloride, fluvoxamine maleate and buspirone hydrochloride) and to identify them. The system was validated with regard to the sensitivity, repetition of data, resistance and particularity. The solvent systems with potential of high separation of components in their mixture were created: acetonitrile, methanol, ammonia solution 25 percent (85:10:5); acetonitrile, methanol, ammonia solution 25 percent (75:20:5); dichlormethane, 1,4-dioxane, ammonia solution 25 percent (50:45:5); dichlormethane, 1,4-dioxane, ammonia solution 25 percent (42:55:3); trichlormethane, 1,4-dioxane, ammonia solution 25 percent (25:70:5); trichlormethane, 1,4-dioxane, ammonia solution 25 percent (60:36:4). One of the most suitable solvent systems for separation of the analyzed mixture (sertraline, amitriptyline, paroxetine, buspirone, fluvoxamine) was determined – acetonitrile, methanol, ammonia solution 25 percent (85:10:5). When this solvent system was used, the average Rf values of the analyzed compounds differed the most. Validation was conducted – the relative standard deviation (RSD, percent) of the average Rf value of the analyzed compounds varied from 0,6 to 1,8 percent and did not exceed the permissible error of 5 percent. The sensitivity of methodology was determined by assessing the intensity of the mixture’s spots on the chromatographic plate. The detection limit of buspirone was 0,0012 µg; sertraline – 0,0008 µg; amitriptyline – 0,0004 µg; fluvoxamine – 0,0004 µg; paroxetine – 0,0008 µg. The resistance of results to the changed conditions – it was determined that when the amounts of the solvents acetonitrile and methanol were increased or decreased to two milliliters, the average Rf values of the analyzed compounds did not change statistically significantly

The use of traditional medicines holds a great promise as an easily available source as effective medicinal agents to cure a wide range of ailments among the people particularly in tropical developing countries like India. The present study investigates the qualitative and quantitative analysis of the major bioactive constituents of N. crenulata leaf extracts. The extractive values of aqueous, acetone and chloroform extracts were found to be 11.34, 4.24 and 6.06 respectively. Qualitative phytochemical analysis of these three solvent extracts confirm the presence of Alkaloids, Saponins, Flavonoids and Phenolic compounds in all the three extracts; however, these phytochemicals were more significant in aqueous extract. Quantitative analysis was carried out using TLC method by different solvent system. Amongst various solvent systems, Butanol: acetic acid: water (9: 0.9: 0.1 v/v/v) shows maximum resolution and number of spots produced at long UV (365 nm) and under iodine vapours. The TLC chromatograms constituted different coloured phytochemical compounds with different Rf values. It can be conveniently used to evaluate the quality of different area samples. This indicates that the leaves can be useful for treating different diseases because the therapeutic activity of a plant is due to the presence of particular class of compounds and thus can serve as potential sources of useful drugs in future.
