Some species of Hemerocallis are widely cultivated for medicinal,edible and ornamental application. Considerable progress had been made in researches on chemical composition and functions of Hemerocallis plants. Previous phytochemical studies on Hemerocallis plants have demonstrated the presence of flavonoids,anthraquinones,alkaloids,terpenoids,triterpenes and triterpenoid saponins,caffeoylquinic acid derivatives,naphthalene glycosides,steroid and steroidal saponins,phenylethanoid glycosides,and lignans. Functional activities of Hemerocallis plants are mainly manifested in sedative hypnotic,antidepressant,antioxidant,anti-tumor,hepatoprotective,antibacterial and insecticidal activities. Chemical composition of Hemerocallis plants is various,and structural type is rich,and has a variety of significant functional activities,so it is worth further study.展开更多

The results indicated that significant effects of magnesium applied to soils were observed in increasing Daylily （Hemerocallis citrina Baroni） yield, improving its growth, and strengthening its antivirus property as well as increasing the amount of exchangeable Mg, N, P, and K in red soil. In particular, the effects of magnesium compound fertilizer Ⅱ （MCF2） with higher Mg content were better than that of the others, which increased Daylily （Hemerocallis citrina Baroni） yield by 57.4, 32.8, and 14.5% compared to that of control treatment （CK）, chemical fertilizer with nitrogen, phosphorus, potassium treatment （CF）, and magnesium compound fertilizer Ⅰ treatment （MCF1） with lower Mg content. It increased soil Alkali N, available P, exchangeable K, and exchangeable Mg by 94.9, 46.5, 31.1, and 35.3%, respectively, compared with that of CK treatment. Therefore, the application of magnesium compound with fertilizer is an optimum method for improving red soil quality.展开更多
