Identification
Morphology
Crepidiastrum denticulatum is a distinct herb characterized by its self-supporting growth form. This plant maintains a modest stature, typically reaching a maximum height of 1.2 meters. Depending on its environment, its vertical development can vary significantly. Individual specimens may stand as short as 0.15 meters, while others often reach a more established height of 0.75 meters. Such variability in size highlights the adaptable nature of this herbaceous species.

Biological Activities
Compounds
Conditions
Crepidiastrum denticulatum responds uniquely to different energy levels of UV-B radiation, specifically when treated with 0.25 W m⁻², 1.0 W m⁻², and 1.25 W m⁻². A treatment of 0.25 W m⁻² increases the plant's antioxidant capacity, total hydroxycinnamic acids content, and several sesquiterpenes without inhibiting growth. In contrast, exposure to the higher energy levels of 1.0 and 1.25 W m⁻² inhibits shoot fresh weight. These higher levels also increase total carotenoid, total HCAs, and H₂O₂ contents while simultaneously destroying chlorophyll pigments. Ultimately, while 0.25 W m⁻² promotes efficient bioactive compound production, the 1.0 and 1.25 W m⁻² treatments cause visible leaf damage and reduced quantum yield.
