Acalypha Indica

Acalypha indica L. is an herbaceous medicinal plant, which is grown abundantly in Bangladesh. Bangladeshi people typically use various parts of this plant for various primary healthcare treatments. The current research was conducted to check and quantify various phytochemicals and mineral components of the assorted parts of Acalypha indica L. The screening analysis shows that studied all phytochemicals were present in the leaf part but not in stem and shoot parts and some were missing or trace amount in root. Total phenol, flavonoid, and tannins content on a dry weight basis ranged from 0.53-0.82 mg GAE/g, 0.02-1.47 mg QE/g and 0.21-0.32 mg TAE/g respectively. Among the phytochemicals the leaf contains the highest amount of flavonoid (1.47 mg QE/g), and lowest in stem (0.02 mg QE/g). Similarly, the amount of minerals like Fe, Zn, K and Pb was 0.23-0.40 mg/kg, 0.01- 0.021 mg/kg, 1.55-2.85 mg/kg and 0.149-0.204 mg/kg respectively. K was the largest volume of mineral for both leaf and stem. Lowest quantity of Zn was observed in most cases. This finding indicates that the studied plant might be good source of phytochemicals. J.

The present study deals with the phytochemical examination of Pachygone ovata (Poer.) Hook.f.& Thoms., an important medicinal plant from menispermaceae family. Leaf and Stem extracts were prepared by using different solvents systems and phytochemical screening was performed using the standard methods given by Harborne. Leaf and stem extracts were prepared from aqueous and organic solvents like petroleum ether, acetone, ethyl acetate and ethanol. Qualitative phytochemical analysis of the petroleum ether, acetone,ethyl acetate, ethanol and aqueous extracts prepared from P. ovata leaf and stem part. Leaf part revealed the presence of alkaloids, flavonoids, glycosides, cardiac glycosides, phenols and tannins. Stem part revealed the presence of alkaloids, flavonoids, glycosides, Resin, Steroids, phenols and tannins. The ethanolic extract showed higher amount of secondary metabolites than the other solvent extracts. This observation becomes important in the context of the therapeutically and drug applications of P. ovata.

Incarvillea emodi (Bignoniaceae) is a rich source of bioactive iridoid glucosides. This plant contains two major iridoid glucosides: plantarenaloside, a neurotropic compound, and boschnaloside, a strong antibacterial compound. Here, in this study we have developed a simple and fast HPLC-DAD method for the total comparative estimation of these two major iridoids from different parts of Incarvillea emodi. A linear calibration curve (r2=0.999) for both iridoid glucosides in varying range (15.6–500 μg/ml) is obtained. The limit of detection (LOD) and limit of quantification (LOQ) for plantarenaloside were 11.4 ng and 38 ng and for boschnaloside were 22.8 ng and 76 ng, respectively. The shoots, roots, and flowers of Incarvillea emodi have a combined presence of 7.66, 1.22, and 6.99 percent of these iridoid glucosides on dry weight basis. In shoots, plantarenaloside shows complete dominance (6.78%) over boschnaloside (0.88%), and a reversal of this trend was observed in case of flowers where boschnaloside shows complete dominance (6.12%) over plantarenaloside (0.87%). The roots contain 1.19% and 0.03% of both iridoids, respectively.

Bean plants (Phaseolus vulgaris L. var. Black Valentine) pretreated with gibberellic acid (hereinafter referred to as GA) absorb and accumulate considerably more N-1-naphthylphthalamic acid (naptalam) than untreated plants. All concentrations of GA from 2.9 × 10−6 to 8.6 × 10−4M were effective; peak influence occurred at 6 × 10−4M. Plants pretreated with this concentration took up 58% more naptalam than untreated plants. When the different parts of the plant were analyzed for naptalam separately, the leaf area (on a per g dry weight basis) was influenced most by GA pretreatment. The leaf area of bean plants pretreated with 2.9 × 10−4M contained 212% more naptalam than the leaf area of untreated plants. The leaf area also included all stem and petiole tissue above and including the first true leaves.

Shorea robusta (Shal) is an important traditional Indian medicinal plant used in various ailments and rituals. The use of different parts of this plant like leaves and resin as a medicament for treatment of various conditions is well documented in literature. However, the studies on phytochemical constituents and medicinal properties in the resin of this plant are scanty. All three samples carried out microscopic characters, ash values, extractive values, T.L.C., and chemical tests. The extractability of methanol, ethanol and chloroform extracts of Shorea robusta were found to be 44.85%, 48.57% and 4.48% respectively. Phytochemical analysis of the extracts of Shorea robusta revealed the presence of alkaloids, flavonoids, triterpenoids and amino acids. The presence of alkaloids and triterpenoids were confirmed by qualitative tests followed by TLC.Key Words: Shorea robusta, phytochemical analysis, triterpenoids, flavonoids.

HERBACE DISSECTION is the process in which samples of herbage cut from trials are separated by hand into component species. Heavy reliance is placed on herbage dissection as an analytical tool ,in New Zealand, and in the four botanical analysis laboratories in the Research Division of the Ministry of Agriculture and Fisheries about 20 000 samples are analysed each year. In the laboratory a representative subsample is taken by a rigorous quartering procedure until approximately 400 pieces of herbage remain. Each leaf fragment is then identified to species level or groups of these as appropriate. The fractions are then dried and the composition calculated on a percentage dry weight basis. The accuracy of the analyses of these laboratories has been monitored by a system of interchanging herbage dissection samples between them. From this, the need to separate subsampling errors from problems of plant identification was, appreciated and some of this work is described here.

Solanum glaucophyllum Desf. (Solanaceae) is traditionally used for curing several health conditions in both human and domesticated animals. There is no data available regarding pharmacognostic standardization and pharmacological activity of this less known medicinal plant. Therefore, the aim of the present work is to prepare pharmacognostic fingerprints of crude drugs obtained from the leaf and stem parts of S. glaucophyllum. Apart from this detailed phytochemical analysis, antioxidant and antimicrobial studies have also been carried out. Pharmacognostic study revealed that the leaves are amphistomatic and stomata are strictly of anisocytic type. Values of stomatal index, palisade ratio, ash content of the investigated parts are found distinct and can be used as pharmacognostic standards for evaluation of crude drugs of this medicinal plant. Phytochemical studies of the leaf and stem parts indicated that phenolics, flavonoids, tannins and alkaloids are present in quite impressible amount. Curcumin content in stem was found very high through HPLC analysis. In DPPH radical scavenging assay, the stem part showed significant antioxidant potential. Ethanol extract of stem produced maximum inhibition zone (11mm) against Pseudomonas aeruginosa at the concentration of 50 mg/ml among five test microorganisms. Some pharmacognostic features recorded in this study as diagnostic ones will help in proper identification of this ethnomedicinal plant in its fresh as well as dried form. On the other hand preliminary phytochemical, antioxidant and antimicrobial studies highlight the S. glaucophyllum as a promising candidate for bioprospecting.

Results of the analysis of twenty-three composite sediment samples revealed that PAHs are widely distributed in the Brisbane River estuary. Mean concentrations for individual compounds, on a dry weight basis, ranged from 0.03 µg/g for dibenz [ah] anthracene to 2.34 µg/g for fluoranthene. Observed PAH assemblages were rich in compounds having pyrolytic origins. However, the presence of petroleum derived compounds was indicative of the importance of petroleum as a PAH source in the estuary. Petroleum refineries, a coal loading terminal and a major treated sewage outfall located at the mouth were not indicated as major contributing sources of PAH pollution in the estuary.
