Volatile Composition, Antioxidant and Antimicrobial Activities of Herbal Plants Used in the Manufacture of Van Herby (OTLU) Cheese

Recent progress on Prangos (Apiaceae) species used in traditional herbal medicine

ETHNOPHARMACOLOGICAL RELEVANCE

Plants have been used for a long time in traditional medicine to treat many diseases. The genus Prangos belongs to the Apiaceae family and has various medicinal and aromatic species. Since ancient times, Prangos species have been employed extensively in traditional medicine for different purposes and are especially popular for their aphrodisiac effects.

AIM OF THE REVIEW

The goal of this paper is to represent a systematic review of the species in the genus Prangos, including their botanical characteristics, uses in traditional medicine, phytochemical constituents, the composition of the essential oils produced, and the biological properties.

MATERIALS AND METHODS

The articles regarding traditional uses and bioactivities of Prangos species were evaluated using electronic databases such as PubMed, Google Scholar, and ScienceDirect. Use of the World Flora Online (WFO) - The Plant List, The International Plant Names Index, the World Checklist of Vascular Plants (2024), and ChemDraw Professional helped complete this compilation.

RESULTS

Phytochemical investigations have indicated that coumarins are characteristic constituents of Prangos species, especially prenylated simple coumarins and furanocoumarins, and also flavonoids, terpenoids, and phytosterols occur in this genus. In addition, the essential oils of these plants have been examined. The biological properties of the Prangos species seem worthy of further investigation. Also, some information about the toxicity of these species and their use as ingredients in food products is presented.

CONCLUSIONS

This review highlights the evaluation of traditional knowledge, phytochemical profiles, biological activities, and potential uses of Prangos species as foods and spices. Many pharmacological activities have been performed related to their traditional uses, but frequently, the exact mechanism of action remains scientifically unproven. This review has compiled data on the phytochemistry, the active secondary metabolites, the biological properties, and recent advances in Prangos species.

Chemical Composition and Biological Activities of Prangos ferulacea Essential Oils

Prangos ferulacea (L.) Lindl, which belongs to the Apiaceae family, is a species that mainly grows in the eastern Mediterranean region and in western Asia. It has been largely used in traditional medicine in several countries and it has been shown to possess several interesting biological properties. With the aim to provide new insights into the phytochemistry and pharmacology of this species, the essential oils of flowers and leaves from a local accession that grows in Sicily (Italy) and has not yet been previously studied were investigated. The chemical composition of both oils, obtained by hydrodistillation from the leaves and flowers, was evaluated by GC-MS. This analysis allowed us to identify a new chemotype, characterized by a large amount of (Z)-β-ocimene. Furthermore, these essential oils have been tested for their possible antimicrobial and antioxidant activity. P. ferulacea essential oils exhibit moderate antimicrobial activity; in particular, the flower essential oil is harmful at low and wide spectrum concentrations. They also exhibit good antioxidant activity in vitro and in particular, it has been shown that the essential oils of the flowers and leaves of P. ferulacea caused a decrease in ROS and an increase in the activity of superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST) in OZ-stimulated PMNs. Therefore, these essential oils could be considered as promising candidates for pharmaceutical and nutraceutical preparations.

The Prangos genus: a comprehensive review on traditional use, phytochemistry, and pharmacological activities

The members of the Prangos genus (Apiaceae) have been widely applied in the Iranian traditional medicine internally and externally for different purposes. The aim of this review is to summarize the ethnomedicinal and food applications of Prangos species and to gather the phytochemical and pharmacological data on this genus. Among the 129 constituents isolated from Prangos species, coumarin derivatives are the main compounds. Several papers report the compositions of essential oils obtained from different plant parts, mostly containing monoterpene and sesquiterpene hydrocarbons. Various pharmacological activities of essential oils, crude extracts or isolated compounds of the Prangos species have been observed, primarily in in vitro experiments. Antioxidant, antimicrobial, cytotoxic and anti-proliferative activities have been the most extensively studied. The efficacy and safety of Prangos plants have not been assessed in animal experiments or clinical trials. Although their furocoumarin content might be a source of adverse effects, toxic effects of Prangos species have not been reported. It can be concluded, that further preclinical and clinical data are necessary to assess the rationale and safety of the medicinal and food use of Prangos species.

Composition and biological activities of the essential oil from a Sicilian accession of Prangos ferulacea (L.) Lindl

Prangos ferulacea (L.) Lindl. (Fam. Apiaceae), is an orophilous species of eastern Mediterranean and western Asia which possesses several biological properties, which are worthy of exploitation in different fields. With the aim to provide new insights into the phytochemistry and pharmacology of this species, a local accession growing in Sicily (South Italy) was investigated as well. Notably, the P. ferulacea essential oil chemical composition and the antioxidant, anti-acetylcholinesterase (AChE) and cytotoxic activities have been studied. This analysis allowed to identify a new chemotype and to report good biological results for this oil.
