DITERPENOID ALKALOIDS FROM THE ROOTS OF A PALE-PURPLE FLOWERING ACONITUM ORIENTALE SAMPLE GROWING IN TURKEY

SUMMARY From the roots of pale purple-flowering Aconitum orientale sample, the norditerpenoid alkaloids septentriodine, lappaconitine, finaconitine, ranaconitine, puberanidine and delstaphinine together with the new alkaloid aconitorientaline obtained for the first time from the white-fowering sample, were isolated. All alkaloids isolated from the white-flowering sample were also obtained from the pale purple-flowering Aconitum orientale sample.All these results show, although they have different flower colors, both samples belong to Aconitum orientale and they are not different species. OZET Kirli-mor cicekli Aconitum orientale koklerinden norditerpenoid alkaloitler septentriodin, lappakonitin, finakonitin, ranakonitin, puberanidin, delstaphinin ve ilk defa beyaz cicekli Aconitum orientale koklerinden yeni madde olarak izole edilen akonitorientalin izole edilerek tanimlanmislardir. Beyaz cicekli Aconitum orientale koklerinden elde edilen tum alkaloitler yeni madde de dahil olmak uzere kirli-mor cicekli ornegin koklerinden de elde edilmistir. Tum bu sonuclar cicek renkleri farkli olmalarina karsin her iki ornegin de Aconitum orientale turune ait oldugunu ve bu orneklerin farkli turler olmadigini kanitlamaktadir.
