New coumestan and coumaronochromone derivatives from Dalbergia boehmii Taub. (Fabaceae)

Daltonkins A and B, Two New Carboxyethylflavanones from the Heartwood of Dalbergia tonkinensis

“…The heartwood of Dalbergia species are used in traditional Chinese medicines for treating cardiovascular diseases including heart failure, myocarditis, myocardial infarction, myocardial fibrosis, and coronary failure . Phytochemical studies of the genus Dalbergia have indicated that its chemical constituents are various flavonoids (including flavones, isoflavones, neoflavones, flavanones, isoflavanones, flavanes, isoflavanes, neoflavans, flavonols, flavanonols, and isoflavanonols), 4‐aryl‐coumarins, phenols, sesquiterpenes, phytosterols, as well as coumestan and coumaronochromone derivatives . The Dalbergia tonkinensis Prain species (commonly called “Sua Do”), is a medium‐size floral species 5–13 m in height that is widely distributed in Vietnam .…”

A New Cytotoxic Ceramide from Dalbergia boehmii Taub. Stem Bark

“…[2][3][4] Phytochemical studies showed that plants from Dalbergia genus contain various classes of compounds as phenolic compounds, stibenes, terpenoids, glycosides, miscellaneous, ...etc. [5,6] As part of our continued screening program of Cameroon medicinal plant constituents especially Dalbergia boehmii, we carried out investigation on the stem barks. Dalbergia boehmii which is known as Ngalayhi in Fulfulde in the Northen Cameroon, is a small to medium-sized deciduous tree or a shrub, used traditionally to treat digestive tract diseases and fever.…”

“…Dalbergia boehmii which is known as Ngalayhi in Fulfulde in the Northen Cameroon, is a small to medium-sized deciduous tree or a shrub, used traditionally to treat digestive tract diseases and fever. [6,7] Previous chemical investigation carried on leaves and hearthwood of D. boehmii leaded to the isolation of thirteen phenolic compounds, mostly isoflavonoids and stilbenes. [6] Further to this, the phytochemical study of the stem barks gave four compounds including a new ceramide named dalbergiamide, a triterpene: olean-12-ene-3,11-dione and two phytosterols:…”
