Abstract
Two new aromatic glycosides, elengiosides A (1) and B (2), were isolated from the methanolic extract of the flowers of Mimusops elengi (Sapotaceae) together with 26 known compounds. Their stereostructures were elucidated based on their spectroscopic properties and chemical evidence. Among the isolates, a phenylethanoid glycoside, undatuside C (14), was found to exhibit hyaluronidase inhibitory activity.


Notes
These compounds were identiied by comparison of their physical and spectral data with those of commercially available samples.
