Erratum: Propolis Components from Stingless Bees Collected on South Sulawesi, Indonesia, and Their Xanthine Oxidase Inhibitory Activity (J. Nat. Prod. (2019) 82: 2 (205−210) DOI: 10.1021/acs.jnatprod.8b00541)

Abstract

The Table of Contents Graphic, page 206, and Figure 1 (page 207): The structure of 1 should be corrected as isorhamnetin, a known flavonoid. We determined this by comparing the spectroscopic data for the natural compound with data for synthesized 1. The correct structure of 1, isorhamnetin, is shown below. (Formula Present) In addition, we named 2 and 3 as "sulawesins A and B", respectively. However, "sulawesin" has been already used as the name of other compounds (J. Nat. Prod. 2017, 80, 2045− 2050). Therefore, we would like to rename 2 and 3 as "sulabiroins A and B", respectively. We apologize for any inconvenience caused by these errors.
