Additional other fully identified pentacyclic triterpenoids were sourced and characterised from Pittosporum angustifolium by Errington and Jefferies (1988). These compounds have structural similarity to compounds isolated from other species,already shown to have anti-tumour and anti-HIV potential (Vesoul and Cock, 2011). Clearly further investigation is required to clarify if these pentacyclic triterpenoids from Pittosporum angustifolium have similar anti-tumour and anti-HIV activity. Pharmacological screening in this study(Table 7) demonstrates that triterpenoids are present in fruit and leaves in our specimen from the Eyre Peninsula in South Australia,but these triterpenoids were not further characterised. Interestingly,a number of the pentacyclic triterpenoid compounds identified by Errington and Jefferies (1988), specifically 23-hydroxyphyllyrigenin and dihydropriverogenin A,were first known from Pittosporum undulatum (Errington and Jefferies,1988), yet no traditional Aboriginal medicinal use is reported for Pittosporum undulatum.
