Objective: To study the chemical constituents form stem bark of Wikstroemia indica.
Method: The constituents were isolated by column chromatography on silica gel and ODS, and identified by spectroscopic methods.
Result: Seven compounds, daphnoretin (I), tricin (II), daucosterol (III), beta-sitosterol (IV), umbelliferone (V), genkwanin (VI), and 6'-hydroxy, 7-O-7'-dicoumarin (VII), were isolated and identified.
Conclusion: Compound VII was a new compound and compounds III, V were isolated from this plant for the first time.

The non-native wood-boring and symbiotic fungus-culturing Xylosandrus germanus (Blandford) was first reported in New York apple orchards in 2013. Trapping surveys have been conducted annually since to assist growers in timely applications of preventative control measures. In 2021, a similar-looking introduced species, Anisandrus maiche (Kurentsov), was identified in traps in west central New York.

This study developed a portable arc iKnife ionization mass spectrometry (AII-MS) technique integrating a surgical knife with low-temperature arc plasma to interact with plant tissues. The thermal energy from the arc plasma induces the sputtering of water-containing plant tissues, leading to the formation of aerosols. These aerosols are then charged by plasma-generated ions, producing charged microdroplets that are ultimately detected by a mass spectrometer.
