  • Title: Plant antitumor agents, 21. Flavones, coumarins, and an alkaloid from Sargentia greggii.
    Author: Meyer BN, Wall ME, Wani MC, Taylor HL.
    Journal: J Nat Prod; 1985; 48(6):952-6. PubMed ID: 4093779.
    Abstract:
    Investigation of the MeOH extracts of Sargentia greggii (Rutaceae) led to the isolation of two known flavones, zapotin and 5,6,2'-trimethoxyflavone, and a new flavone, 5,6,2',3',4',6'-hexamethoxyflavone (1), whose structure was established by spectral data and confirmed by total synthesis. In addition, two known coumarins, 3-(alpha,alpha-dimethylallyl) herniarin and seselin, and a new coumarin, O-geranylosthenol (3), have been isolated from this plant. The structure of 3 was deduced from spectral data. Although the crude extracts displayed KB activity, none of the crystalline compounds were significantly active.
