Recently, 6-hydroxydihydrosanguinarine (34) has been reported as a new alkaloid isolated from Dactylicapnos torulosa Hook f et Thoms. [125,126]. The compound is described as an amorphous solid of yellow colour, however, the substance e diibits major discrepancies in ipectral data with the structure given [127]. 6-Hydroxydihydrochelerythrine has allegedly been isolated from Toddalia aculeata Pers. in the form of its acetic acid ester [128], However, its H NMR data are not in agreement with those previously published for this compound [129]. Universally, 6-hydroxydihydroderivatrves (pseudobases) are unstable semiaminoacetals with basic character which cannot occur in acidic plant tissues at all and could not be isolated as natural products especially after 5% HCl has been used in the isolation procedure cf. 125,128].
