| Abstract: | A rare anthocyanin, malvidin 3-O-rhamnoside, was isolated from the blue flowers of Parochetus communis Buch.-Ham. ex D. Don along with two known flavonols: kaempferol 3-O-(2-O-glucosyl-6-O-rhamnosyl)-glucoside and kaempferol 3-O-(2,6-di-O-rhamnosyl)-glucoside. These structures were identified using Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS). |
