Thalictrum faberi

Thalifabine (304), C41H46N209, was obtained, with thalifaberine (302, Section II,C,115), from Thalictrum faberi as an amorphous yellow solid, [ct] 5 +78.3° (c 0.53, MeOH). The alkaloid shows spectral behavior quite similar to... [Pg.83]

Dehydrohuangshanine (472), C42H4gN2Og, [a] ,3 +42.2° (c 0.17, MeOH), isolated from Thalictrum faberi Ulbr. (Ranunculaceae), was assigned its structure from instrumental data (IR, UV, MS, NMR, CD) and comparison to the co-occurring huangshanine (167) (545). [Pg.179]

Thalifabatine (514), C41H48N209, [ot]J2 +60.5° (c 0.154, MeOH), is a trace alkaloid of Thalictrum faberi. By MS and NMR comparison, it was deduced that 514 is the hydroxylated analog of thalifaberine (302), which was extensively studied by NOEDS. The CD curve indicated the same absolute configuration as 302 (545). [Pg.192]

Thalifarapine (515), C40H46N208, amorphous, [a] 4 +98.6° (c 0.422, MeOH), was isolated from Thalictrum faberi. MS and NMR comparisons with related co-occurring alkaloids, as well as a UV base shift, established the position of the lone OH substituent (545). [Pg.193]

Thalifasine (516), C40H46N2O9, [a] [67.9° (c 0.80, MeOH), is the last of the six 12 —8 ether-linked aporphine-benzylisoquinoline dimers (the others being 302,304,473, 514, and 515) isolated from Thalictrum faberi. The UV base shift of the alkaloid and a NMR study of its O, O-diacetate suggested the indicated location of the hydroxy substituents. The CD curve, closely resembling that of thalifaberine (302), indicated the same configuration (545). [Pg.193]

Thalifaboramine is but one of over 16 new aporphine-benzylisoquinoline dimeric alkaloids that have been isolated from Thalictrum faberi Ulbr., and the crude basic fraction, as well as most of the new alkaloids, including thalifaboramine (79), have demonstrated cytotoxic effects against the P-388 carcinoma cell [133],... [Pg.67]

Dehydrothalifaberine, an alkaloid of the Chinese Thalictrum faberi Ulbr., was found to possess significant cytotoxicity as measured against the P-388 cell line [129]. [Pg.139]
