“…The genus Ceropegia s.s. (Apocynaceae) includes over 200 species of milkweed‐related plants distributed across the eastern hemisphere, where they are an important source of pyridine alkaloids (e.g., cerpegin) and other compounds used in folk medicine to treat gastric disease and distress (Muthukrishnan, Franklin Benjamin, Sathishkannan, Senthil Kumar, & Rao, 2013). The urn‐shaped flowers of Ceropegia spp.…”

Coevolutionary processes, which have governed interactions between organisms throughout the history of life, also serve as an engine of ecosystem services for humans. The escalating arms races between plants and herbivores, flowers and pollinators, have generated a cornucopia of foods, raw materials, perfumes, spices, ornamentals, medicines, and drugs. Human history is replete with aesthetic as well as economic inspiration drawn from such plants. Our future may depend on similar inspiration, as we confront novel health, agricultural, and environmental challenges in the face of global change. Summary "Coevolution" was coined to conceptualize escalating arms races between plants and herbivores in evolutionary time, often mediated by natural products.

Ethnobotanical Uses, Nutritional Composition, Phytochemicals, Biological Activities, and Propagation of the Genus Brachystelma (Apocynaceae)

et al. 2022

The Brachystelma genus (family: Apocynaceae) consists of geophytes that are traditionally utilised among rural communities, especially in East Africa, southern Africa, West Africa, and northern and western India. Apart from being used as a food source, they are indicated as treatment for ailments such as colds, chest pains, and wounds. This review provides a critical appraisal on the ethnobotanical uses, nutritional value, phytochemical profiles, and biological activities of Brachystelma species. In addition, we assessed the potential of micropropagation as a means of ensuring the sustainability of Brachystelma species. An inventory of 34 Brachystelma species was reported as a source of wild food and traditional medicine (e.g., respiratory-related conditions, pains, and inflammation) across 13 countries, predominantly in Africa and Asia. Brachystelma circinnatum and Brachystelma foetidum were the most popular plants based on the high number of citations. Limited data for the nutritional content was only available for Brachystelma edulis and Brachystelma naorojii, as well as phytochemical profiles (based on qualitative and quantitative techniques) for five Brachystelma species. Likewise, a few Brachystelma species have evidence of biological activities such as antimicrobial, antioxidant, and acetyl cholinesterase (AChE) inhibitory effects. Extensive studies on Brachystelma togoense have resulted in the isolation of four compounds with therapeutic potential for managing different health conditions. As a means of contributing to the sustainability of Brachystelma species, micropropagation protocols have been devised for Brachystelma glabrum, Brachystelma pygmaeum, Brachystelma ngomense, and Brachystelma pulchellum. Nevertheless, continuous optimisation is required to enhance the efficiency of the micropropagation protocols for these aforementioned Brachystelma species. Despite the large number of Brachystelma with anecdotal evidence as food and medicine, a significant number currently lack empirical data on their nutritional and phytochemical profiles, as well as their biological activities. The need for new propagation protocols to mitigate the declining wild populations and ensure their sustainability remains pertinent. This is important should the potential of Brachystelma species as novel food and medicinal products be achieved.
