ABSTRACT
OBJECTIVE: To Analyze the volatile chemical components of Ficus carica fruits. METHODS: The volatile components of Ficus carica fruits were extracted by the three extraction methods such as SPME, SD and SE, and then analyzed by GC-MS. RESULTS: A total of 91 peaks were identified by GC-MS. 61 compounds came from the extraction methods of SPME, 7 compounds from SD, and 30 compounds from SE. CONCLUSION: The volatile components extracted by the three methods are not quite similar. Among of them, the volatile components extracted by SPME method are the most and have the highest resolution.

OBJECTIVE: To analyze the compositions of volatile constituents in Astragali Complanati Semen. METHODS: The volatile constituents were extracted with headspace solid phase micro extraction (HS-SPME), and identified by GC-MS. RESULTS: 51 compounds were separated from Astragali Complanati Semen and 25 of them were identified, which made up 78.85% of the total amount. The main components obtained from Astragali Complanati Semen were L-Bornyl acetate (14.1%), Camphor (5.98%) and L(-)-Borneol (4.27%). CONCLUSION: The compounds in Astragali Complanati Semen are firstly confirmed,which provides scientific evidence for the development of Astragali Complanati Semen.

OBJECTIVE: The chemical components of essential oil from Anaphalis aureopunctata were analyzed by GC-MS. METHODS: Essential oil was extracted by stem distillation (SD). The chemical components of essential oil were analyzed by GC-MS. RESULTS: The main components in the oil were Eudesma-4(14), 11-diene, alpha-Bisabolol,6,10,14-trimethyl- 2-Pentadecanone,Caryophyllene oxide,alpha-Selinene and so on. CONCLUSION: This is the first time to adopt GC-MS to analyze the chemical components of volatile oil of Anaphalis au-reopunctata, and this study can provide science basis for further research development of Anaphalis aureopunctata.

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.

OBJECTIVE: To establish the HPLC fingerprint spectrum of flavonoids from Gynostemma pentaphyllum. METHODS: The HPLC conditions with TURNER Kromasil C18 column (250 x 4. 6 mm, 5 microm) was used, the mobile phase consisted of 0.4% phosphoric acid-methanol-acetonitrile with gradient elution at flow rate of 0.5 ml/min and the detection wavelength was set at 360nm. RESULTS: Ten common characteristic peaks were taken as fingerprint peaks the presision and the retest are in accordance with the requirement. CONCLUSION: The method is stable, reliable, precision and provides a scientific basis for the quality standard of Gynostemma pentaphyllum.
