	Title	Flavonoid Aglycones in the L eaf Resin o f Som e Cistus Species
	Abstract	Members o f the genus Cistus excrete a leaf resin that consists mainly o f terpenoids. This resin also contains methylated flavonoids as aglycones. Rare methyl deri vatives o f myricetin have been isolated from C. monspeli-ensis, along with uncommon methyl derivatives o f quer-cetin. Further flavonoids encountered in the leaf resin o f this and six further species are methyl derivatives o f kaempferol and quercetin, som e o f apigenin and in one species also o f luteolin. The results indicate that there might exist species-specific flavonoid patterns.

	Title	A Chemical Investigation of Pueraria mirifica Roots
	Abstract	Ten isoflavonoids including daidzein, daidzin (daidzein-7-O-glucoside), puerarin (daidzein-8-C-glucoside), genistein and coumestrol have been isolated from a methanolic extract of Pueraria mirifica roots. Apart from these known compounds and mirificin, a novel apioside derivative of puerarin, the roots have also been found to contain three minor coumestans and one 5-deoxyiso-flavone for which only limited spectroscopic data are currently available.
