Medicinal plants are being utilized as raw material and the use has increased in recent decades due that these biosynthesize compounds with several pharmacological activities. Some plant species with biological potential are of interest to the industry for preparation of drugs, phytodrugs, or food supplements. This causes overexploitation and deforestation, which endangers plant species-of-interest. In recent years, alternatives have been sought to eradicate this problem. A solution that was give and is maintained is plant biotechnology, which favors the production of active Secondary Metabolites (SMt). Plant biotechnology allows us to increase the yield of a compound-of-interest, reduces its production times and costs, and allows constant and controlled production of the raw material, and while aiding in the protection of medicinal plants that are found in danger of extinction. In the scientific literature, procuring the SMt by means of biotechnological processes is described, highlighting the study of four species from Mexican traditional medicine (Lopezia racemosa, Galphimia glauca, Cnidoscolus chayamansa, Sphaeralceae angustifolia and Buddleja cordata), and the main biological activities are as follows: anti-inflammatory, hepatoprotector, neuroprotector, anxiolytic, antitumoral, antibacterial, and antioxidant, among others.

Almost everyone in Indonesia has used medicinal plants to treat diseases and it is recognized and felt the benefits of these medicinal plants in curing the disease they suffer. Throughout the archipelago, various indigenous tribes living around the forest have utilized various plant species to maintain health and treat various diseases. However, the process of inheriting local knowledge and the entry of modern culture into traditional society is mostly done orally and the entry of modern culture into traditional society is feared to cause local knowledge to be lost. The diversity of plant species in the vicinity has its own peculiarities between one community group and another. Southeast Sulawesi where there are various ethnicities, including areas that use many types of plants for traditional medicine.

Ancient Times

Agaves are plants used in the production of alcoholic beverages and fibers. Ever since ancient times, pre-Hispanic cultures in Mexico have used them in traditional medicine to cure different ailments. Over the years, studies of the active principles responsible for the therapeutic benefits of agaves have increased. Leaves and fibers are the main agro-wastes generated in tequila and mezcal production, while fibers are the main waste product in the textile sector. Different investigations have referred to the agro-waste from agave processing as a source of bioactive molecules called secondary metabolites (SM). Among them, phenols, flavonoids, phytosterols, and saponins have been extracted, identified, and isolated from these plants. The role of these molecules in pest control and the prospect of metabolites with the biological potential to develop novel drugs for chronic and acute diseases represent new opportunities to add value to these agro-wastes. This review aims to update the biological activities and recent applications of the secondary metabolites of the genus Agave.

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.

Purpose: Flavonoids are a group of secondary metabolites of the polyphenols class present in several plant species. Among them, the biflavonoid agathisflavone is of interest since it bears several biological effects that include: antiviral, antitumoral, antiprotozoal and neurogenic actions. In this sense, this study aims to use the important tool of scientific prospecting to assess the level of research development concerning the flavonoid agathisflavone. Methods: The experimental design was carried out through strategic reach with keywords on the PubMed (National Center for Biotechnology Information - NCBI) and Science Direct platforms. The articles were compiled and exported to Microsoft Office Excel 2007, where they were analyzed, stored and distributed in charts organized as to different countries, year of publication of scientific articles and journals RESULTS: The prospective research resulted in the identification of 81 scientific productions, published in several journals, submitted by different countries, in several areas of medical domain and in different years of publication over the last 50 years (1965 - 2018). It was also possible to investigate the advances in the study of agathisflavone for the development of new therapeutics. Conclusion: Although agathisflavone has been known in the literature since at least 1969, only 23 of the eligible articles found evaluated its possible therapeutic effects. The demonstrated biological activities of agathisflavone range from antiprotozoal to neurogenesis and neuroprotection, however, the molecule needs to be better studied at the in vivo and human level.

Plant species used as herbal medicines play an important in the provision of primary healthcare in several rural communities. The current study was aimed at documenting medicinal plants used by the inhabitants of Alfred Nzo District Municipality in the Eastern Cape province, South Africa. Information on medicinal plants used for primary healthcare was collected through open-ended interviews with a sample of 124 participants selected via snowball-sampling technique between April 2017 and May 2018. A total of 34 plant species and one fungus species representing 20 families were used in the treatment of 13 different human diseases. The major diseases treated by the documented species included respiratory system, pain, sores and wounds, infections and infestations, digestive system, blood and cardiovascular system, fever and malaria, general ailments, reproductive system and sexual health and mental disorders. Popular herbal medicines with relative frequency citation (RFC) values exceeding 0.50 included Bulbine frutescens, Clivia miniata var. miniata, Elephantorrhiza elephantina, Centella asiatica, Hypoxis hemerocallidea, Dicerothamnus rhinocerotis, Leonotis leonurus, Agapanthus africanus and Datura stramonium. Such repository of medicinal plants and fungi reinforces the need for an evaluation of their biological activities as a basis for developing future medicines and pharmaceutical products.

Background: The genus Achillea L. is rich in bioactive sesquiterpenes and flavonoids; most of the studied species exhibit several biological activities and are used as emmenagogue, wound healing and analgesic agents. Some species are also used in local folklore medicine. Objective: Following a literature survey, we discuss the anti-cancer properties of Achillea species, taking into consideration ethnopharmacological data on their use in traditional medicine for the treatment of cancer. In addition, we screened extracts and isolated secondary metabolites from A. coarctata for cytotoxicity, upon information based on local traditional medicine. The plant was collected in Kozani (Northern Greece), where it is locally used for treating gastrointestinal disorders, including stomach cancer. Methods: A selection of the relevant data was performed through a search in PubMed, Scopus, Google Scholar and Science Direct databases. In addition, extracts and isolated compounds from A. coarctata were tested for their in vitro activity against the human cancer cell lines MCF-7 and HeLa. Conclusion: The genus Achillea L. is a valuable source of bioactive secondary metabolites. The most significant outcome of the investigation of medicinal plants is the documentation and the assessment of the traditional information and its use and perspectives in the light of modern pharmacology.
