The fluminense vegetation, more specifically the flora from the Jurubatiba restinga has been investigated by a multidisciplinary team of botanists, chemist, radiobiologist, insect physiologists and geneticist. Vouchers of 564 specimens have been collected, identified, organized in an herbarium, and a database is being build up containing, in addition to classical botanical data, chemical data and information on the potential economic use either for landscape gardening, alternative foods or as medicinal plants. Phytochemical studies of the Guttiferae, Clusia hilariana, yielded oleanolic acid and nemorosone. Their biological activities against the haematophagous insect Rhodnius prolixus vector of Chagas disease have been investigated. Finally, it has been observed that aquatic plants possessed high levels of the natural radionuclide polonium-210, which seems to be originated mainly from soil rather than from atmospheric supply.

Background: Native Americans have had a rich ethnobotanical heritage for treating diseases, ailments, and injuries. Cherokee traditional medicine has provided numerous aromatic and medicinal plants that not only were used by the Cherokee people, but were also adopted for use by European settlers in North America. Methods: The aim of this review was to examine the Cherokee ethnobotanical literature and the published phytochemical investigations on Cherokee medicinal plants and to correlate phytochemical constituents with traditional uses and biological activities. Results: Several Cherokee medicinal plants are still in use today as herbal medicines, including, for example, yarrow (Achillea millefolium), black cohosh (Cimicifuga racemosa), American ginseng (Panax quinquefolius), and blue skullcap (Scutellaria lateriflora). This review presents a summary of the traditional uses, phytochemical constituents, and biological activities of Cherokee aromatic and medicinal plants. Conclusions: The list is not complete, however, as there is still much work needed in phytochemical investigation and pharmacological evaluation of many traditional herbal medicines.

Plants have been used as a source of medicine for the treatment of different diseases from thousands of years ago. There is numerous evidences are available for use of plants as a medicine in the treatment of diseases in Indian, Egyptian, Chinese, Greek and Roman system of medicine. Pharmacognosy is the study of medicines derived from natural sources, mainly from plants which may further lead to development of new drug. The exploration, extraction and screening of biological diversity such as herbs, spices, microbes and other natural resources is the worldwide activity in recent years. Phytochemicals are the naturally available bioactive compounds which are derived from different plant parts and are primarily responsible for biological activities. The most important chemical compounds which are present in the plants are alkaloids, phenols, saponins, carbohydrates, terpenoids, steroids, flavonoids and tannins etc.

Introduction: Medicinal plants play a significant role in the health maintenance in underdeveloped countries, herbs and spices continue serve as a new sources for herbal medicines. Aim: The objective was to investigate phytochemical screening and biocidal activity on stem bark Chrysophyllum albidum (Linn) and straw Aristolochia ringens using chloroform. Methods: Chloroform extracts of C. albidum and A. ringens were obtained and screened for phytochemical constituents. The colour intensity or the precipitate formation was used as analytical responses to these tests. The Antimicrobial activities crude extracts were evaluated against some microorganisms with broth microdilution test. The extracts were screened for in-vitro cytotoxic activity against breast tumour and liver tumour cells. Results: The results of the phytochemical screening revealed the presence of alkaloids, saponins, steroids, anthraquinone and glycosides. C. albidum and A. ringens chloroform extracts revealed high quantities of alkaloid and flavonoid respectively. While cardiac glycoside and anthraquinone were found with low quantity in C. albidum and A. ringens extracts respectively. C. albidum showed promising bacterial activity against Escherichia coli and cytotoxic activity to liver tumour cells. While A. ringens, showed excellent bacterial activity against Bacillus cereus and good fungal activity against Candida albicans. A. ringens also showed cytotoxic to liver tumour and breast tumour cells. The observed antimicrobial and cytotoxic effects may be due to the antagonist or synergistic effect of the secondary metabolites identified in the extracts. Conclusion: Medicinal plants studied showed good potential biological activities that support the idea that traditional medicines remain useful healthcare in developing countries

Over the last years, great interest has arisen concerning plant stilbenes, especially resveratrol, which has a whole spectrum of positive biological activities. In this study, we investigated the presence of resveratrol monomers (trans- and cis- form) and naturally occurring derivatives of fraas-resveratrol (piceid, astringin and isorhapontin) in phenolic extracts of twenty medicinal plants traditionally used in Croatian folk medicine. The investigated compounds were present in the samples, in free form or as glucosides, and the highest share was found in immortelle, common yarrow and Lamiaceae plants. The obtained results indicate that biological activity of selected medicinal plants can be related to the presence of this valuable group of phytochemicals.
