This study was designed to investigate triterpenoids from the roots of Rosa laevigata Michx. The silica gel column chromatography was used to separate the chemical constituents from the roots of Rosa laevigata Michx. HPLC was used to analyze its purity and chemical constitution. Spectroscopy methods were used to determine their structures. Five constituents were isolated and identified as19α-OH-3β-E-feruloyl corosolic acid (1), 23-hydroxy-tormentic acid (2), 2α, 3β, 19α, 23- tetrahydroxy-12-en-28-oleanolic acid (3), 2α, 3α, 20β- trihydroxyurs-13 (18)-en-28-oic-acid (4), 2α, 3β, 20β-trihydroxyurs-13 (18)-en-28-oic-acid (5). Compound 1 was assigned as a new compound, compounds 4, 5 were obtained from the genus Rosa for the first time.
Objective To study the chemical constituents from the stem ofAralia chinensis.Methods The constituents were isolated and purified by ODS chromatography repeatedly,and the structure was identified by spectral analysis.Results A new saponin was isolated from the stem ofA.chinensis.And its structure was identified as 3-O-{[β-D-glucopyranosyl-(1 →2)]-[β-D-glucopyranosyl(1→6)-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranosyl}-oleanolic acid 28-O-[β-D-glucopyranosyl ester (1).Conclusion Compound 1is a new saponin named as congrnujingnoside A.
Objective To study the chemical from the roots of Rosa multiflora var.cathayensis.Methods The silica gel column chromatography was used to separate the chemical constituents from the roots of Rosa multiflora var.cathayensis.HPLC was used to analyze its purity,chemical and spectroscopy methods were used to determine their structures.Results Nine constituents were isolated and identified as multifloside A (1),arjunic acid (2),1β-hydroxyeuscaphic acid (3),arjunetin (4),kaji-ichigoside F1 (5),euscaphic acid (6),tormentic acid (7),myrianthic acid (8),and rosamultin (9).Conclusion Compound 1 is a new compound named multifloside A;All compounds are obtained from the genus Rosa for the first time.
Objective:To establish the fingerprint analysis method for the root of Rosa laevigata Michx from different regions by UPLC. Methods:The column was ACQUITY UPLC? Phenyl(2.1 mm × 100 mm,1.7 μm). The mobile phase consisted of methanol-water with gradient elution. The flow rate was 0. 2 ml·min-1 , the detection wavelength was 210 nm, the column temperature was 30℃, and the injection volume was 3 μl. Results:The fingerprint consisted of 15 common peaks. The range of similarity for twelve bat-ches of the root of R. laevigata Michx was 0. 489-0. 942. And the reference fingerprint of the root of R. laevigata Michx was estab-lished by UPLC. Conclusion:The fingerprint method is simple and reproducible, which can provide basis for the quality control and the medicinal resources exploration.
