Anagallis arvensis

The transformation of the lanostane keto-epoxide (72) into the cucurbitacin derivative (73) has been achieved with boron trifluoride in acetic anhydride. The presence of the acetic anhydride appears to favour the backbone rearrangement. The structure of (73) was confirmed by correlation with the oxidation product (74) of deoxybryogenin acetate. Two new cucurbitacin glycosides, arvenins 1 (75) and II (76) from Anagallis arvensis, have been reported. ... [Pg.160]

Arvenins III (36) and IV (37) are two further cucurbitacin glucosides from Anagallis arvensis. The former was reported last year from Ecballium elaterium (see Vol. 9, p. 193) while the latter has been isolated, together with the related glucosides (38) and (39) and iso-23,24-dihydrocucurbitacin D (40), from the roots of Bryonia alba. °... [Pg.142]

Salvia broussoneti. Its structure was confirmed by interrelation with germanicone. Lantolic acid (97), from Lantana camara, provides a rare example of C-25 oxygenation. The 13(28)-epoxy-derivative (98) has been isolated from Anagallis arvensis. [Pg.171]

Description The botanical description of this plant is very similar to that of Anagallis arvensis. This species differs by having a blue corolla. Some botanists consider Anagallis coerulea a form or variety of Anagallis arvensis. [Pg.38]
