Another example for SFE of alkaloids using basified modifiers was reported for cephalotaxine (7) from Cephalotaxus wilsoniana leaves [45]. In this report, basified methanol was found to greatly enhance the extraction efficiency relative to any other modifiers (Figure 13). 

Cephalotaxus harringtonia (32) gave two alkaloids, 3-epi-2,7-dihydrohomoerysotrine (53) and 2,7-dihydrohomoerysotrine (54), whereas Cephalotaxus wilsoniana (34) afforded wilsonine (60) and epiwilsonine (61). Alkaloids 57, 58, and 59 were isolated from Phelline comosa Labiil. (33), and holidinine (52) and comosidine (57) were isolated from Phelline sp. aff. (25).

The alkaloids were best isolated from the ethanol extract of the plant material, partially fractionated by counter-current distribution, and subsequently purified by preparative chromatography. Of the 11 known Cephalotaxus alkaloids (105-115 in Figs. 8 and 9), cephalotaxine (105a) is ubiquitous and the most abundant (up to 64% of the total alkaloid extract) in all species examined. C. wilsoniana Hay., which yields only minor quantities of cephalotaxine, is the exception, however it is rich in Homoerythrina alkaloids,... 

Arguing from structural similarities, it was originally suggested (10) that the Cephalotaxus alkaloids could be derived in vivo from the same precursor as the aromatic erythrina bases, but since Cephalotaxus and homoerythrina alkaloids have been isolated (90) from E. wilsoniana, it has been postulated (10b, 89) that both groups have a 1-phenethyltetrahydroisoquinoline as a common precursor (Scheme 36). Tyrosine is incorporated (122) into cepha-lotaxine, but the labeling pattern did not seem to be consistent with a...
