Isolation of antimicrobial compounds from guava (Psidium guajava L.) and their structural elucidation.
Four antibacterial compounds were isolated from leaves of guava (Psidium guajava L.), and the structures of these compounds were established on the basis of chemical and spectroscopic evidence. Two new flavonoid glycosides, morin-3-O-alpha-L-lyxopyranoside and morin-3-O-alpha-L-arabopyranoside, and two known flavonoids, guaijavarin and quercetin, were identified. The minimum inhibition concentr...
متن کاملCarotenoids from guava (Psidium guajava l.): isolation and structure elucidation.
Sixteen carotenoids were isolated from the flesh of Brazilian red guavas (Psidium guajava L.). Their structures were established by means of UV-visible, 400 and 500 MHz (1)H NMR, 120 and 125 MHz (13)C NMR, mass, and circular dichroism spectra. The carotenoids were identified as phytofluene, (all-E)-, (9Z)-, (13Z)-, and (15Z)-beta-carotene, (all-E)-gamma-carotene, (all-E)-, (9Z)-, (13Z)-, and (1...

متن کاملCharacterization of volatile compounds in guava (Psidium guajava L.) varieties from Colombia
The guava (Psidium guajava L.), which has unique and quince-banana like flavor, is an economically important subtropical fruit in many tropical countries on all seasons. Volatile constituents from three Colombian varieties of guava fruits: Coronilla (commonly named guayaba común), Palmira ICA-1 (commonly named guayaba pera) and Glum Sali (commonly named guayaba manzana) were isolated by headspa...
