Abstract From the MeOH residue of Smallanthus sonchifolius stems and leaves, three new sesquiterpene derivatives, namely smallantholides A − C (1 − 3), and two know phenyl propanoid glycosides (4 and 5), were isolated using various chromatographic techniques. The structural elucidation was confirmed by spectroscopic methods including 1D, 2D NMR, CD and HR-TOF-MS. Moreover, the in vitro α-glucosidase inhibitory activity of 1 − 5 was also evaluated.

1 Introduction Light-based 3D printing generally involves converting reactive liquid resins into solid materials by spatiotemporally controlled photopolymerization, allowing the creation of complex and high-resolution 3D objects.[1] In order to adapt 3D objects to advanced applications such as tissue engineering, microfluidics, and electronics,[2] besides their topological design, it is highly desirable to control surface properties and functionalities of 3D structures, particularly in a...
