RESUMEN
OBJECTIVE: To study chemical constituents of Dendranthema indicum var. aromaticum. METHODS: The constituents were separated and purified by column chromatography with silica gel and Semi-preparative HPLC. Their structures were identified on the basis of physical-chemical properties and spectral data. RESULTS: Seven compounds were isolated and identified as acacetin, apignein, acacetin-7-O-beta-D-glucopy ranoside, apignein-7-O-beta-D-glucopy ranosids, luteolin, beta-sitosterol and daucosterol. CONCLUSION: Apigenin, acacetin-7-O-beta-D-glucopy ranoside and apignein-7-O-beta-D-glucopy ranoside are obtained from the plant for the first time.

OBJECTIVE: The chemical components of essential oil from Magnolia biondii were analyzed by GC-MS. METHODS: Essential oil was extracted by steam distillation (SD). The chemical components of essential oil were analyzed by GC-MS. RESULTS: The chemical components in the oil were qualitatively and quantitatively analyzed by GC-MS. 63 components were separated and 50 components were identified. The main components were Eucalyptol (28.92%), P-pinene (12.39%), alpha-Terpineol (8.28%). CONCLUSION: This is the first time to adopt GC-MS to analyze the chemical components of volatile oil of Magnolia biondii, and this study can provide science basis for further research development of Magnolia biondii.
