The Australian plant Discaria pubescens (Brongn.) Druce (Rhamnaceae) was previously found to contain the cyclopeptide alkaloid pubescine (1); it thus resembles the Argentinian species D. longispina (2), which also contains cyclopeptide bases. On the other hand, the Chilean plant D. serratifolia (3) and the New Zealand D. toumatou (4) contain simple benzylisoquinoline alkaloids only, while another South American species, D. crenata, has been found to produce both types of bases (5). In a reexamination of D. pubescens for minor alkaloids, a fresh sample was collected at approximately the same time of year and from the same region as that used in the initial study (1), and extracted in a similar fashion. As in the case of D. toumatou (4), it had been observed previously that the plant material gives a strong alkaloid test in the field, which diminishes rather rapidly in intensity after collection, but if the fresh material is immersed in methanol as soon as possible, the alkaloid content is stabilised. A careful examination of the methanol extract revealed no trace of cyclopeptide bases, and the only alkaloid to be isolated was (+)-R-coclaurine, a widespread benzylisoquinoline base which here, as usual, occurs in a partly racemised form (6); its identity was confirmed by conversion to its N-methyl and O, N-dimethyl derivatives. This unexpected result may be due to the drought conditions suffered by the plants during the three years previous to collection, in contrast to the conditions prevailing at the time of the original study. A reexamination of the other Discaria spp. under different growth conditions would be of considerable interest.
