“…Epimedium comprises approximately 57 species, and only 5 of them (i.e., Epimedium brevicornu , Epimedium sagittatum , Epimedium koeanum , Epimedium pubescens and Epimedium wushanense ) are officially recorded in the Pharmacopoeia of the People's Republic of China (Zhang et al . ). Among them, Epimedium brevicornu was frequently employed to produce functional foods such as healthy tea, noodles, bread and alcoholic beverages (Zhang et al .…”

A protocol of enzymatic water extraction was developed to isolate antiradical and DNA damage inhibitory polysaccharides from Epimedium brevicornu (EbP) using single factor experiments and orthogonal test for the first time. Compared to conventinal heating extraction, enzymatic water extraction dramatically enhanced extraction yield, shortened extraction duration, reduced extractant consumption and decreased extraction temperature. Structural features of EbP were investigated by infrared spectroscopy. And some other physicochemical properties like solubility of EbP were identified. EbP obtained by enzymatic water extraction exhibited ability to scavenge DPPH• and ABTS+• radicals. Consistent with their free radical‐scavenging activities, Epimedium polysaccharides possessed protective effect against plasmid DNA damage induced by oxidative stress. In summary, enzymatic water extraction seems to be a promising technique for separating Epimedium polysaccharides, which might act as a natural antioxidant or a chemopreventive agent due to their free radical‐scavenging capacity and protective activity against DNA damage caused by oxidative stress. Practical Applications Polysaccharides are considered one of the most important bioactive constituents in the famous edible medicinal plant, Epimedium brevicornu. In the present study, enzymatic water extraction of polysaccharides from Epimedium brevicornu was optimized for further large‐scale industrial processing for the first time. Epimedium polysaccharides obtained by enzymatic water extraction have proved to possess antioxidant and DNA damage inhibitory activities, which show great potential for becoming a nutraceutical in healthy foods or even a phytopharmaceutical.

“…Our study clearly shows that the number and insertion of the leaves and the number of leaflets varies in this species. Upon extensive specimen examination, Zhang et al (2011, 2015b) observed that the leaves of E. simplicifolium T. S. Ying were mainly unifoliolate, occasionally trifoliolate, and the leaves of E. acuminatum Franch. may be unifoliolate.…”

“…may be unifoliolate. Subsequently, E. simplicifolium was synonymized with E. acuminatum (Zhang et al 2011). Hence, as a taxonomist, it is important to study as many collections as possible (Xu 1998).…”

Due to some common or similar features (e.g., small leaf, spurless, yellow flower), three Chinese species of the genus Epimedium (Berberidaceae), E. ecalcaratum, E. platypetalum, and E. campanulatum, are controversial based on morphological characteristics. In the present study, the descriptions of morphological characteristics for the three species were revised based on extensive studies and observations both in field and in herbaria. In general, E. ecalcaratum has long creeping rhizomes 1–3 mm in diameter, two alternate or opposite trifoliolate leaves, 7–14 flowers, and petals obovate and apex subacute. Epimedium platypetalum has short or long-creeping rhizomes 1–3 mm in diameter, one trifoliolate leaf, 2–6 flowers, and petals oblong and apex rounded. Epimedium campanulatum has compact rhizomes 4–6 mm in diameter, two alternate or opposite trifoliolate leaves, 15–43 flowers, and petals obovate and apex rounded. Through comparison, we found that despite the close affinity of these three species, they can be distinguished by rhizome differences, stem-leaves, the morphology of flower (e.g., petals), and the number of per inflorenscence.

“…Ying was described by Ying (1975), only separating it from Epimedium acuminatum in having unifoliolate, sericeous leaves. Upon extensive specimen examination, however, Zhang et al (2011) found that the diagnostic characters of Epimedium simplicifolium were within the range of morphological variations of Epimedium acuminatum and placed Epimedium simplicifolium into synonymy.…”
