Pluchea sagittalis (Lam.) Cabrera, (quitoco or erva lucera) is commonly used to treat digestive disorders in Southern Brazil and countries of the South Cone. The crude aqueous extracts from the leaves, stalks or flowers were used in acute oral toxicity in mice and in pharmacological studies to determine the gastrointestinal transport of water, sodium, and potassium in rats. The oral administration of 5000 mg/kg of extracts examined did not produce signs of intoxication nor induce the death of any mice during the period of 14 days. The extracts from the leaves and stalk have reduced the absorption of water in the jejunum and jejunum and ileum, respectively with relation to the control. There was an absorption of sodium with the administration of these extracts, especially those from the flowers, when compared with that of the control. There was an increase in the absorption of potassium in different parts of the gastrointestinal tract in comparison to that of the control, being increased in most parts with the application of extracts from the stalks. It could be concluded that the extracts from the stalk, leaves and flowers of P. sagittalis have substances that alter the absorptive characteristics of several portions of the gastrointestinal mucosa.

Autotoxicity of aqueous extracts from roots, stems and leaves of flowering Chinese cabbage (Brassica campestris L. ssp. chinensis var. utilis Tsen et Lee) were studied by hydroponic in different concentrations (0.5g/L, 2g/L, 5g/L). The results showed that in solution with aqueous extracts from roots, stems and leaves, the growth of flowering Chinese cabbage were inhibited, leaf chlorophyll content declined, photosynthesis rate were affected, activities of SOD, POD and CAT were changed, MDA concentration increased, thus cell membrane permeability of flowering Chinese cabbage was damaged. The autotoxicity of aqueous extracts in flowering Chinese cabbage increased with the extracts concentration increasing.

ABSTRACT The benefits of various foods, such as fruits and vegetables, have been the focus of several studies aimed at improving welfare, health, and reducing the incidence of diseases. Therefore, the present paper objectified to investigate the presence of molecules of biotechnological and pharmacological interest in peel, seed, and pulp of Annona x atemoya Mabb. Aqueous extracts of the fruit parts were obtained with different buffers and assessed as to their protein and phenolic compounds content. The three parts of the fruit presented different proportions of these compounds when subject to different extraction conditions, with the highest concentrations of proteins being found in the seed and phenolic compounds in the peel of the studied fruit. Bioactive proteins (protease inhibitors and lectins) were detected through inhibitory tests for trypsin and chymotrypsin and hemagglutinating activity tests with human erythrocytes. A variation of 400 to 9600 inhibition units for the trypsin in the analyzed extracts, whereas for chymotrypsin a variation of 200 to 2500 in the inhibition units for the three fruit parts, considering the different extraction conditions were identified. The extracts obtained from the seeds and the peel presented titers higher than 0.9 hemagglutination units, suggesting that the by-products from the processing of A. x atemoya are potential sources of bioactive molecules.

Plant chemicals abound in different parts of plants, in different compositions. Thus, the comparative screening of the leaf, stem-bark and root of Azadirachta Indica becomes imperative. The presence of nine phytochemicals which include; Alkaloids, Flavonoids, Saponins, Glycosides, Phenols, Steroids, Tannins, Reducing sugars and Anthraquinones, and the quantity of alkaloids, flavonoids, saponins, tannins and glycoside in the leaf, stem-bark and root of Azadirachta indica were investigated. The plant parts were collected from a plantation grown in Okpotegu Echara, Ikwo Local Government Area of Ebonyi State, Nigeria. Plant samples were  air dried at room temperature, ground into uniform powder, sieved, bottled and labeled, ready for physico – chemical analysis. Results of the investigation revealed that anthraquinones were beyond detection limits in all the plant parts tested in both ethanol and aqueous extracts. Alkaloids were not detectable in leaf, stem-bark and root samples of aqueous extract. Glycosides were not detectable in leaf sample of ethanol and aqueous extracts. Quantitatively, the phytochemical compositions of each part showed higher concentrations of Alkaloids in the leaf, stem-bark and root (11.63%, 4.93% and 3.79%), compared to flavonoids (2.19%, 2.72% and 0.92%), saponins (0.70%, 1.12% and 0.44%), tannins (0.33 mg/100, 0.50mg/100 and 0.17mg/100) and glycosides (0.23%, 0.27% and 0.19%), respectively. Obviously, except for the higher percentage (11.63%) of alkaloids in the leaf, the phytochemicals in the stem-bark are higher as shown by the results, which could support the reason that the bark is preferably chewed commonly together with the stem as chew stick for its germicidal and antifungal action.

Brocchia cinerea (Vis.) is an Asteraceae-family plant widely used in traditional medicine in Southeastern Morocco to treat several ailments. The aqueous extracts of flowers, leaves, stems and aerial parts of B. cinerea were subjected to a preliminary phytochemical screening test for various constituents. The polyphenols, flavonoids, and tannins contents were determined. Moreover, the antioxidant activity was evaluated by DPPH scavenging assay and ferric reduction antioxidant power. However, the antibacterial activity was evaluated against six pathogenic bacteria. Phytochemical screening of different parts of B. cinerea revealed alkaloids, flavonoids, saponins, tannins, and terpenoids. The leaves extract showed the highest polyphenols concentration (27.15±0.92 mg GAE/g of Ext) and flavonoids (17.46±0.66 mg QE/g of Ext), while flowers extract was highest in tannin (9.57±1.24 mg TAE/g of Extract). All extracts of B. cinerea showed moderate to high antioxidant power, among which the leaves extract demonstrated the strongest antioxidant activity, with an IC50 value of 0.99 mg/mL and an optical density of 1.15. In the case of antibacterial activity screening, leaves extract showed the highest inhibition zone diameters ranging from 9 to 27 mm against the tested bacteria. The results demonstrate that the aqueous extracts of different parts of B. cinerea, especially the leaves, could be developed as pharmaceutical products.
