Abstract:
Objective To study the chemical constituents from the leaf of Syringa oblata. Methods The compounds was isolated by silica gel column chromatography and HPLC, and their structure were identified by spectral data analysis. Results A total of 35 compounds were isolated and identified as oleanolic acid (1), ursolic acid (2), betulinic acid (3), 1,3-benzodioxole-5-propanol (4), p-hydroxyl benzene propyl alcohol (5), p-hydroxyl benzene ethel alcohol (6), syringopicrogenin D (7), syringopicrogenin E (8), syringopicrogenin F (9), syringopicrogenin A (10), syringopicrogenin C (11), 3,4-dihydroxyl benzene ethel alcohol (12), syringobittergenin B (13), syringo-picrogenin B (14), grasshopper ketone (15), (7R,8S)-4,9,9’-trihydroxyl-3,3’-dimethoxyl-7,8- dihydrobenzofuran-1’-propylneolignan (16), lariciresinol (17), syringin (18), 3(Z)-enol glucoside (19), quercetin-3-O-β-D- glucopyranoside (20), (8E)-ligstroside (21), epipinoresinol-4-O-β-D-glucopyranoside (22), (8E)-ligstroside B (23), (8E)-ligstroside A (24), salidroside (25), 7-dehydrologanin (26), fliederoside B (27), syringopicroside B (28), oleoside dimethyl ester (29), lilacoside (30), syrigopicroside (31), oleuropein (32), (+)-lariciresinol-4-O-β-D-glucopyranoside (33), verbascoside (34), and (+)- epipinoresinol-4’-O-β-D-glucopyranoside (35). Conclusion Compounds 4, 5, 14-16, 19, 23, 24, 26, and 27 are isolated from S. oblata for the first time.
