| 520 | 3 | _aIn Ephedra andina, E. breana and E. frustillata three colourless compounds are present which upon treatment with mineral acid yield delphinidin, pelargonidin and apigeninidin. Prodelphinidin is present in young shoots, while the other two compounds occur in subterraneous parts and, in smaller quantities, in older shoots. There is evidence that the substance yielding delphinidin is an oligomer of higher molecular weight, which due to its tanning capacity may provide chemical defence. The substances which yield delphinidin and apigeninidin are probably monomers or dimers of lower molecular weight; no ecological role can be indicated for them. | |
