Chemotaxonomy - Opis:
- Phytochemical investigation of the roots of Furcraea bedinghausii Koch. Led to the isolation of a mixture of two new homoisoflavones, 5,7-dihydroxy-3-(3,4-methylenedioxybenzyl)-chromone (4a) and 5,7-dihydroxy-3-(4-methoxybenzyl)-chromone (4b), together with the known β-sitosterol (1), 7,4'-dihydroxyhomoisoflavane (2), dihydrobonducellin (3), kaempferol (5), 5,7-dihydroxy-3-(4-hydroxybenzyl)-chromone (6), 1-linoleylglycerol (7), 6’-linoleyl-3-O-β-D-glucopyranosyl-β-sitosterol (8), trans-3,3’,5,5’-tetrahydroxy-4’-methoxystilbene (9), yuccaol C (10), yuccaol D (11), 3-O- β -D-glucopyranosyl- β -sitosterol (12), 4-[6-O-(4-hydroxy-3,5-dimethoxybenzoyl)-β-D-glucopyranosyloxy]-3-methoxybenzoic acid (13) and two pairs of steroidal saponins: (25R)-2α-3β–dihydroxy-5α-spirostan-12-one 3-O-β-D-glucopyranosyl-(1→2)-O-[β-D-xylopyranosyl-(1→3)]-O-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (14a) and (25R)-2α-3β–dihydroxy-5α-spirost-9-en-12-one 3-O-β-D-glucopyranosyl-(1→2)-O-[β-D-xylopyranosyl-(1→3)]-O-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (14b), (25R)-3β–hydroxy-5α-spirostan-12-one 3-O-β-D-glucopyranosyl-(1→2)-O-[β-D-xylopyranosyl-(1→3)]-O-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (15a) and (25R)-3β–hydroxy-5α-spirost-9-en-12-one 3-O-β-D-glucopyranosyl-(1→2)-O-[β-D-xylopyranosyl-(1→3)]-O-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (15b). Their structures were elucidated by interpretation of spectral data and by comparison with literature.
