Coumarins fromPeucedanum wulongense

Abstract

A new angular dihydropyrancoumarin named wulongensin A, along with five known coumarins, (-)-anomalin, umbelliferone, (-)-smyrinol, 3'(S),4'(S)-disenecioyloxy-3',4'-dihydroseselin, (+)-trans-khellactone, was isolated from the root of Peucedanum wulongense. The structure of wulongensin A was established as 3'(R)-angeloyloxy-4'(R)-isovaleryloxy-3',4'-dihydroseselin by spectroscopic methods and the absolute configurations were deduced by chemical correlations with known compounds.

A Review on Anomalin: A Natural Bioactive Pyranocoumarin from the Past to the Future

“…Isolation and purification procedures of anomalin are also summarized in Table 1. As can be seen, anomalin was obtained from either aerial part and roots of the plant by extraction with petroleum ether, [36,56,57,60,68] hexane, [59,62,[64][65][66][67] diethyl ether, [70] chloroform, [51] methanol, [24,26,38,39,45 -50,52 -54,61,69,70] ethanol, [40,44,55,73,74] acetone, [41,[57][58][59] etc. at room temperature or by reflux.…”

“…Sheh. [51] and P. japonicum Thunb. [46][47][48] Urbagarova et al (2020) also mentioned it as (+)-praeruptorin B from Ligusticum elatum (Edgew.)…”

“…Similarly, (−)‐anomalin was isolated from P. wulongense Shan & M.L. Sheh [51] . and P. japonicum Thunb [46–48] .…”

α-Pinene, Caryophyllene and β-Myrcene from Peucedanum terebinthaceum Essential oil: Insecticidal and Repellent Effects on Three Stored-Product Insects

“…It has been reported that Peucedanum species were usually rich in essential oils and coumarins [43,44], which were basic substances for most reported pharmacological activities [45]. The yield of essential oils was various, as it could be dependent on several factors such as season [46,47], harvested stage [48] and plant part [49,50].…”
