“…Numerous plants store highly active compounds in the leaves, the most important plant part in the present study, and these compounds confer significant antibacterial and antioxidant effects [54][55][56]. Teas containing infusions are among the most common medicinal preparations globally.…”

Despite the fact that Mexico has vast biocultural biodiversity, there are numerous regions where the traditional medicinal use of plants has not yet been studied. We aimed to document, analyze quantitatively, and preserve medicinal plant knowledge among local people living in over 40 communities in the state of Zacatecas. Ethnobotanical information was collected by semistructured interviews with 132 informants. Data were analyzed using standard quantitative indices such as relative frequency of citation, family importance value, cultural importance index, and informant consensus factor. We recorded 168 medicinal plant taxa belonging to 151 genera and 69 botanical families and used to treat 99 health disorders. The most medicinally important plant families were Asteraceae (20 species), followed by Fabaceae and Lamiaceae (12 species) and Cactaceae (five species). The most culturally important species was Matricaria chamomilla L., mentioned 140 times, followed by Arnica montana L. (62 times) and Artemisia ludoviciana Nutt (48 times). The highest consensus for use was for diseases of the reproductive system. The type of disorder for which there was the highest number of references for use (389; 25% of all uses) and plant species (67) were diseases of the digestive and gastrointestinal system. The present study represents the first quantitative medical-ethnobotanical documentation and analysis of the traditional use of medicinal plants in Zacatecas state. Despite the semiarid climate, this region is botanically highly diverse, and its flora have versatile medicinal uses.

“…Tea made from leaves of Prunus serotina, in Mexico called Capulin, is used as a natural remedy for stomach upsets, hypertension, diarrhoea, paludism, bronchitis, mouth infections and coughs (Ibarra-Alvarado et al 2009). Leaves and flowers of black cherry are used in the treatment of intestinal, cardiovascular and pulmonary diseases (Camacho-Corona et al 2015).…”

Key Message The best yields in the extraction of hydroxycinnamic acids, flavanols and total phenolics from black cherry flowers were obtained with 40% ethanol and the poorest with water. A 30% higher content of total phenolics was obtained from leaves by using methanol rather than water. Context Black cherry (Prunus serotina Erhr.) is widespread in Europe. Because it is an invasive species, most research has been aimed at trying to find a method to remove this shrub from forests. The incentive for the development of the research was that we were trying to find a possible folk use of black cherry leaves and flowers. Aims The aim of this work was to study the detailed phenolic profile of extracts of P. serotina leaves and flowers. Methods Three types of extracts of P. serotina were made. The extracts were analysed for differences in phenolics content based on different extraction methods. HPLC-MSn was used to identify the phenolic compounds, and HPLC–DAD was used for their quantification. Results The results show that different extraction methods result in differences in the amount of extractables. Flavanols are the main group of identified compounds in both leaves and flowers. A larger extraction efficiency leads to a higher amount of phenolics in the flowers compared to leaves (49.8 vs. 36.5 g/kg dry weight). No difference was detected in the amount of phenolics between water extracts of leaves and flowers. Each extract can be considered rich in phenolics. Conclusion This work shows that leaves and flowers of P. serotina are a rich source of phenolic compounds. We provide interesting results that might be of interest in the industrial valuation of several compounds.

“…Finally, an extract from the aerial parts of Condea albida (syn. Hyptis albida ) obtained with a mixture of dichloromethane and methanol (1:1) demonstrated effectiveness against strains of Trichomonas vaginalis (GT-13) (MIC 11.4 μg/mL) and Giardia lamblia (0989:IMSS) (MIC 16.1 μg/mL) ( Camacho-Corona et al, 2015 ). The effect against Giardia lamblia could explain the use of this plant for the treatment of gastrointestinal disturbances ( Martínez, 1979 ).…”

Ethnopharmacological relevance The subtribe Hyptidinae contains approximately 400 accepted species distributed in 19 genera ( Hyptis , Eriope , Condea , Cantinoa , Mesosphaerum , Cyanocephalus , Hypenia , Hyptidendron , Oocephalus , Medusantha , Gymneia , Marsypianthes , Leptohyptis , Martianthus , Asterohyptis , Eplingiella , Physominthe , Eriopidion and Rhaphiodon ). This is the Lamiaceae clade with the largest number of species in Brazil and high rates of endemism. Some species have been used in different parts of the world mainly as insecticides/pest repellents, wound healing and pain-relief agents, as well as for the treatment of respiratory and gastrointestinal disorders. Aim of the review This review aims to discuss the current status concerning the taxonomy, ethnobotanical uses, phytochemistry and biological properties of species which compose the subtribe Hyptidinae. Materials and methods The available information was collected from scientific databases (ScienceDirect, Pubmed, Web of Science, Scopus, Google Scholar, ChemSpider, SciFinder ACS Publications, Wiley Online Library), as well as other literature sources (e.g. books, theses). Results The phytochemical investigations of plants of this subtribe have led to the identification of almost 300 chemical constituents of different classes such as diterpenes, triterpenes, lignans, α -pyrones, flavonoids, phenolic acids and monoterpenes and sesquiterpenes, as components of essential oils. Extracts, essential oils and isolated compounds showed a series of biological activities such as insecticide/repellent, antimicrobial and antinociceptive, justifying some of the popular uses of the plants. In addition, a very relevant fact is that several species produce podophyllotoxin and related lignans. Conclusion Several species of Hyptidinae are used in folk medicine for treating many diseases but only a small fraction of the species has been explored and most of the traditional uses have not been validated by current investigations. In addition, the species of the subtribe appear to be very promising as alternative sources of podophyllotoxin-like lignans which are the lead compounds for the semi-synthesis of teniposide and etoposide, important antineoplastic agents. Thus, there is a wide-open door for future studies, both to support the popular uses of the plants and to find new biologically active compoun...
