“…As an essential element for chlorophyll synthesis, Fe is an important component and activator of many enzymes in plants [ 35 ], and is involved in redox and electron transfer, which directly or indirectly affects photosynthesis, respiration, and material–energy conversion [ 36 ]. Therefore, the scientific and reasonable supplementation of Fe fertilizer is an important way to alleviate reductions in medicinal plant yield and quality [ 37 ]. Our experimental results show that the leaf surface-spraying of mineral elements was an effective measure to enhance the flavonoids content in E. sagittatum during the harvest period; in particular, the highest total flavonoid content was reached after 20 days of high-Fe 2+ (2500 mg·L −1 ) treatment.…”

The harvesting period is a critical period for the accumulation of flavonoids in the leaves of the important medicinal plant Epimedium sagittatum. In this study, we conducted an experiment on E. sagittatum leaves sprayed with mineral elements with the aim of improving the quality of the herbal leafage during the harvesting period. We elucidated the changes in flavonoids (icariin, epimedin A, epimedin B, and epimedin C) in E. sagittatum leaves. The sum of main flavonoids content reached a maximum (11.74%) at 20 days after the high-concentration Fe2+ (2500 mg·L−1) treatment. We analyzed the FT-IR spectra characteristics of E. sagittatum leaf samples using the FT-IR technique, and constructed an OPLS-DA model and identified characteristic peaks to achieve differentiated identification of E. sagittatum. Further, widely untargeted metabolomic analysis identified different classes of metabolites. As the most important characteristic flavonoids, the relative contents of icariin, icaritin, icariside I, and icariside II were found to be up-regulated by high-Fe2+ treatment. Our experimental results demonstrate that high-concentration Fe2+ treatment is an effective measure to increase the flavonoids content in E. sagittatum leaves during the harvesting period, which can provide a scientific basis for the improvement of E. sagittatum leaf cultivation agronomic measures.

“…The bulb of Bowiea volubilis has long been known to be a source of several cardiac glycosides [42,55]. Cardiac glycosides are steroidal compounds that have proved to be fruitful in developing potential drugs for congestive heart failure [21]. Cardiac glycosides have long been isolated and characterized in B. volubilis [56][57][58].…”

“…The sugar moieties of cardiac glycosides often contain unusual 2-deoxy sugar that influences their structure, pharmacological properties, and side effects [21]. In the case of cardiac glycoside ingestion, enzymes in the body hydrolyse the glycosidic bonds, which result in the release of bioactive steroidal compounds and sugar moieties [58].…”

“…These different preparation methods can ultimately affect the bioactive compounds' content and influence the therapeutic effects of the plant. For instance, the bulb of B. volubilis is commonly used to treat a wide range of illnesses, including respiratory infections, gastrointestinal disorders, and skin diseases, and can be prepared in different ways, including boiling, drying, and grinding into a fine powder [20,21]. The leaves and stems of B. volubilis are used to treat various ailments, including hypertension, fever, and arthritis.…”

Bowiea volubilis subsp. volubilis is primarily used to address human respiratory infections, coughs, and colds due to its diverse pharmaceutical properties. Notably, the plant contains alkaloids that exhibit notable antifungal, antibacterial, and cytotoxic properties. Additionally, the presence of saponins, with recognized antioxidant and anticancer attributes, further contributes to its medicinal potential. Steroid compounds inherent to the plant have been associated with anti-inflammatory and anticancer activities. Moreover, the bulb of B. volubilis has been associated as a source of various cardiac glycosides. Despite these therapeutic prospects, B. volubilis remains inedible due to the presence of naturally occurring toxic substances that pose risks to both animals and humans. The review focuses on a comprehensive exploration concerning B. volubilis ethnobotanical applications, phytochemical properties, and diverse biological activities in relation to in vitro and in vivo applications for promoting human health and disease prevention. The aim of the study is to comprehensively investigate the phytochemical composition, bioactive compounds, and potential medicinal properties of Bowiea volubilis, with the ultimate goal of uncovering its therapeutic applications for human health. This review also highlights an evident gap in research, i.e., insufficient evidence-based research on toxicity data. This void in knowledge presents a promising avenue for future investigations, opening doors to expanded inquiries into the properties and potential applications of B. volubilis in the context of human diseases.
