Pharmacognostical investigations on Helichrysum pallasii (Sprengel) Ledeb: Pharmacognostical investigations on Helichrysum pallasii (Sprengel) Ledeb. Cubukcu, B.; Bingol, S. (Fac. Pharm., Univ. Istanbul, Istanbul, Turk.). Plant. Med. Phytother., 18(1), 28-35 (English) 1984. CODEN: PLMPA9. ISSN: 0032-0994. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11 Apigenin [520-36-5], luteolin [491-70-3], naringenin [480-41-1], 3,5-dihydroxy-6,7,8-trimethoxyflavone [14221-65-9], apigenin 7-glucoside [578-74-5], luteolin 4'-glucoside [6920-38-3], luteolin 7-glucoside [5373-11-5], naringenin 4'-glucoside [81202-36-0], helichrysin A [529-41-9], helichrysin B [23711-00-4], and isosalipurposide [4547-85-7] were isolated from the capitula of H. pallasi, while the 1st 7 compds. were isolated from leafy stems. The anatomical structure of the stems and leaves and the morphol. properties of the pollen grains of H. pallasii showed that the plant carries distinct features of Compositae plants. When the qual. and quant. results of the anal. of the flavonoids of the plant are compared with those obtained from the capitula of medicinal species H. arenarium, it is obsd. that the major and minor flavonoid compn. of the 2 species is similar with the exception of galangin and kaempferol derivs. Thus, H. pallasii is a new source to be used as a herbal drug raw material in Turkey.
