Ferns (Pteridophyta) is the oldest group of plants on earth that has more than 11.000 species. Ethnobotany and pharmacological studies have revealed that ferns contain potentially secondary metabolites as medicine. Purwodadi Botanic Gardens (Purwodadi BG) has fern collections that have not revealed information about drug potential. This research was conducted to inventory Purwodadi BG’s fern collections which have potential as medicine and to determine their conservation status. Inventory of fern collections is carried out by collecting data from the Registration Unit and observing directly in the field, while information about drug potential is obtained by literature review. A total of 31 species of 171 specimens of Purwodadi BG’s fern collections are known to be efficacious for treating various diseases, both traditional medicine, and research results. As many as 6 species of fern collections that have medicinal potential are included in IUCN Red List and categorized as least concern/LC and critically endangered/CR. The potential for medicinal plants of fern collections include anti-oxidants, anti-inflammatory, anti-microbial, anti-viral, and anti-cancer properties. This potential information is expected to increase the value of the fern’s function and their conservation efforts.

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.

Abstract A review of literature data on the degree of peat decomposition – an important parameter that yields data on environmental conditions during the peat-forming process, i.e., humidity of the mire surface, is presented. A decrease in the rate of peat decomposition indicates a rise of the ground water table. In the case of bogs, which receive exclusively atmospheric (meteoric) water, data on changes in the wetness of past mire surfaces could even be treated as data on past climates. Different factors shaping the process of peat decomposition are also discussed, such as humidity of the substratum and climatic conditions, as well as the chemical composition of peat-forming plants. Methods for the determination of the degree of peat decomposition are also outlined, maintaining the division into field and laboratory analyses. Among the latter are methods based on physical and chemical features of peat and microscopic methods. Comparisons of results obtained by different methods can occasionally be difficult, which may be ascribed to different experience of researchers or the chemically undefined nature of many analyses of humification.

Medicinal plants are a great source of medicine for treating various human ailments. Traditional use of herbal medicine, which was developed within an ethnic group before the development and spread of modern science, is the very basis and an integral part of various cultures. Different medicinal systems throughout the globe are still operational and use natural herbs for treating diseases. Traditional Chinese Medicine (TCM), Ayurveda, Kampo, Traditional Korean Medicine (TKM), and Unani are some commonly found traditional medicinal systems in use today. They are used directly, or their secondary metabolites are used as anti-bacterial, antifungal, immunomodulators, anti-hair fall, and multiple other purposes. However, their blood purification properties prevent blood from toxicity. Hundreds of medicinal plants are used in Ayurveda for blood purification, particularly plants which are astringent or bitter (pungent or sharp tastes). In addition, medicinal herbs do not have side effects.
