“…This study showed the presence of terpenes, betulinic acid, ursolic acid, oleanolic acid, palmitoleic acid, hexadecanoic acid, and other compounds. Other members of Chrysobalanaceae (Tommasi et al, 2003), such as Chrysobalanus, Coupeia and Parinarium also presented similar chemical composition, with tannins, flavonoids, diterpenes, terpenes and steroids as secondary metabolites (Bilia et al, 1996;Oberlies et al, 2001;Fernandes et al, 2003;Zuque et al, 2004;Castilho et al, 2005;Carvalho et al, 2008;Carvalho and Costa, 2009).…”

This work describes the chemical composition, and evaluates the antimicrobial and antioxidant activities of a hydroalcoholic extract from the leaves of the Licania tomentosa. Gram positive and negative bacterial strains were used in this work. Examination of the phytochemical composition of L. tomentosa revealed the presence of secondary metabolites such as tannins, flavonoids, saponins, alkaloids, steroids and triterpenoids. An antibacterial assay pointed out that the extract had a lower minimal inhibitory concentration (MIC - 32 μg/mL) towards Staphylococcus aureus (ATCC12692). The extract also presented antibacterial activity against other assayed bacteria, with the MIC varying between 64 and 512 μg/ mL. Our findings reveal that the extract presented an antioxidative capacity lower than that of BHT at the same concentration, used as positive control. Our results suggest that the levels and combinations between the secondary metabolites of this plant should be investigated to explain the demonstrated antibacterial activity

“…This structural similarity allows it to be transported into cytosol by (GLUT2) in the plasma membrane of βcells for selective uptake and accumulation in the pancreatic βcells. It is a well-known diabetogenic agent that is used to induce diabetes with characteristics similar to type1 in experimental animals (Carvalho and DaCosta, 2009). The drug has been noted to exert its diabetogenic effects when administered parenterally, i.e., intravenously, intraperitoneally or 576 subcutaneously.…”

This study was designed to investigate the glucose levels and markers of oxidative stress on alloxan-induced diabetic wistar rats treated with ethanolic leaf extracts of 1:1 mixture of Piper guineense (PG) and Tetracarpidium conophorum (TC). A total of thirty rats weighing between 100-150g were used for this study. They were divided into six (6) groups comprising Normal control (received distilled water), Negative control (received 100mg/kg body weight of alloxan), Positive control (2.5mg/kg body weight) and test groups which received 300mg/kg body weight of Ethanol Extract of P. guineense (EAPG2), Ethanol Extract of T. conophorum (EATC3), Ethanol Extract of P. guineense + T. conophorum in ratio1:1 (EAPGTC4). Diabetes was induced by intraperitoneal administration of 100mg/kg body weight of alloxan (A) for seven days. After treatment, the result showed that fasting blood glucose level in the test groups had significant (p<0.05) decrease when compared to the alloxan treated group only. Also, the oxidative stress markers indicated significant (p<0.05) decrease in malondialdehyde (MDA) and significant (p<0.05) increase in antioxidant enzymes superoxide dismutase (SOD), catalase(CAT) and reduced gluthatione (GSH) comparable to test groups. Histopathological examination of the pancreas and liver tissue showed recovering and good cellularity on the pancreas and liver tissues. From the findings of this study, it can be concluded that 300mg/kg body weight of P. guineense and T. conophorum (1:1 mixture) exhibited hypoglycemic and antioxidant potentials ameliorating damages brought about by alloxan.

“…These are terpenes, betulinic acid, ursolic acid, oleanolic acid, palmitoleic acid, hexadecanoic acid, and other compounds. Other members of Chrysobalanaceae [43], such as Chrysobalanus, Coupeia and Parinarium also presented similar chemical composition: flavonoids, tannins, diterpenes, terpenes and steroids as secondary metabolites [44,45,46] herbs and spices may not only be due to its total phenolics but also to the other groups of phytochemicals present. This finding marks a significant contribution as a prevention of cancer especially that these herbs and spices are readily available and can be found as condiments to any cooking procedure.…”

Aims: To establish an ethnobotanical data on the various species of herbs and spices in selected areas of North Cotabato. Study Design: The study was carried out using observational and descriptive survey type of research Place and Duration of Study: The study was conducted from January 2013 to January 2014. Methodology: this study was conducted using structured interview and actual field survey visit. Samples collected were identified using field Guidelines by Remollo [1]. Selected samples of plants were propagated in a nursery and Conservation and distribution status were determined using the Redlist 2010. Results: A total of forty-eight (48) species of herbs and spices belonging to thirty-eight (38) genera and twenty-seven (27) families were found in four study areas in North Cotabato. The species richness and abundance and the diversity index were generated on the study. Out of the 48 species, Euphorbia neriifolia Linn was categorized as critically endangered, Cinnamomum mercadoi Vidal (Kalingag), Dillenia philippinensis Rolfe (Katmon) and Koordersiodendron pinnatum (Blanco) Merr. (Amugis) belong to the vulnerable category (VU), and four belong to near threatened category (NT) namely: Hoya multiflora (Blume) Desne, Pangium edule Reinw. Ex Blume, Peperomia pellucida (L.) HBK. and Morinda umbellata Linn. Various parts of the plants were used as herbs and spices. These were the fruits, seeds, young leaves or shoots, flowers, bark and saps, young stems, rhizomes, tubers that were prepared and cooked with different dishes. Two plant species, Atuna racemosa Rafin.ssp. racemosa and Euphorbia neriifolia Linn were subjected to phytochemical screening and were positive for saponins, alkaloids, flavonoids and tannins. Both showed absence of anthraquinones. Conclusion: A baseline survey of indigenous herbs and spices in the four study sites with emphasis on the characterization of species richness and abundance.
