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.

The use of plants as therapeutic agents is part of the traditional medicine that is practiced by many indigenous communities in Ecuador. The aim of this study was to update a review published in 2016 by including the studies that were carried out in the period 2016–July 2021 on about 120 Ecuadorian medicinal plants. Relevant data on raw extracts and isolated secondary metabolites were retrieved from different databases, resulting in 104 references. They included phytochemical and pharmacological studies on several non-volatile compounds, as well as the chemical composition of essential oils (EOs). The tested biological activities are also reported. The potential of Ecuadorian plants as sources of products for practical applications in different fields, as well the perspectives of future investigations, are discussed in the last part of the review.

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.

The roots of Iostephane heterophylla are popular in Mexican traditional medicine and as such are a good candidate to develop herbal drug preparations to be used as phytomedicine. International criteria for validation and standardization of a herbal product as phytomedicine include, among others, the integration of microscopic and histochemical characteristics of the raw material, as in this case the herbal drug, to guarantee its authenticity. As an original contribution to the knowledge of the root structure of this species, fresh roots fixed in FAA, were processed with conventional histological techniques (paraffin embedment and subsequent transversal and longitudinal sections that were stained with safranin-fast green) and stained with histochemical markers for identification of cellular contents. The root description includes dermic, fundamental and vascular tissues as well as cellular contents (proteins, polysaccharides, polyphenols, condensed and hydrolyzed tannins, starches and lipids, some of which have been isolated in previous phytochemical studies). These characteristics are compared to those of other species of Asteraceae as an initial comparative study to contribute to identify medicinal plants based upon their underground parts.

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

Acanthaceae is popularly known as acanthus family which belong to mint order – lamiales. They are distributed from tropics to a temperate region such as India, Malaysia, Brunei, Indonesia, Brazil, Central America and Africa. Most members of this family are therapeutically important since they are in the up to date usage by ethnic communities. Andrographis paniculata, Clinacanthus nutans, Graptophyllum pictum, Hemigraphis alternata, Justicia gendarussa and Strobilanthes Crispus are some of the medicinal plants of Acanthaceae family. These plants are recognized for their biopharmaceutical potential usage in traditional medicine. These plants have a plethora of phytochemical compounds such as flavonoids, phenolic compounds, glycosides, terpenoids, benzenoids, quinine, triterpenoids and naphthoquinone present in various parts of the plant that plays a vital role in drug industries. The pharmacological properties of these plants such as anti-bacterial, anti-diabetic, anti-cancer, anti-oxidant, anti-inflammatory, anti-arthritis, hepatoprotective, anti-viral and anti-hypertensive are in general practice as an alternative and complementary medicine in both ethnobotanical and pharmacological fields. This article encompasses not only the comprehensive survey based on the electronic resources, scientific journals but also the books that summarize the botanical, phytochemical properties of these plants and also accentuate their significant role in both ethnobotanical and pharmacological fields. It is felt that this article would provide more insight into the health benefits of some plants of the Acanthaceae family.
