Aim: To provide the foundation for reasonable utilization by analyzing the essential oils of Sabina pingii var. wilsonii.. Methods: The essential oils were extracted using steam distillation and separated with GC capillary column. The components were quantitatively determined with normalization method, and were preliminarily identi-fied by GC-MS. Results: 79 Components were identified, which took up 93. 78% of the essential oils. Conclusion: The main components of essential oils were a-terpineol( 16. 70%); α-fenchene( 14. 98%); 2,6,10-dodecatrien-1-ol, 3,7, 11-trimethyl-( 6.49%); 1, 4-cyclohexadiene, 1-methyl-4-[1-methylethyl]-( 4. 74%); kaura-5, 16-dien-18 [orl9]-ol(3. 62%); naphthalenemethanol, 1, 2, 3, 4, 4a, 5, 6, 7-octahydro-α, α, 4a, 8-tetramethyl-, [2R-cis]-(3. 04%); [ + ]-4-carene ( 2. 81%); D-limonene ( 2. 71%); β-myrcene ( 2. 59%); cedrol (2.40%); a-pinene (2. 36%); 7-isopropyl-1, 1, 4a-trimethyl-1 ,2,3,4,4a, 9,10,10a-octahydrophenanthrene(2. 32%).
ABSTRACT
Objective To investigate the effect of Fructus Psoraleae on the proliferation and differentiation of cultured osteoblast isolated from neonatal rat's calvarium.Methods Calvarium osteoblasts of new born SD rat were cultured and exposed to different concentrations of Fructus Psoraleae extract,then the content of alkaline phosphatase(ALP)in the cell was measured and the cell proliferation was detected by tetrazoline colorimetry(MTT).Results Ethyl acetate extract and alcohol extract from Fructus Psoraleae can improve the activity of ALP and the proliferation of rat's cultured osteoblasts,the optimum concentration was 2.0?10-3 mg/mL.Conclusion Ethyl acetate extract and alcohol extract from Fructus Psoraleae can stimulate the differentiation and proliferation of osteoblasts in vitro.
ABSTRACT
AIM: To determine coumarin and flavonoid in Compound Buguzhi Sustained-Release Tablet(Fructus Psoraleae,etc). METHODS: HPLC method was developed.The separation was performed on an ODS column with the mobile phase of CH_3OH-H_2O.The flow rate was 1 mL/min and the detection wavelength was 320 nm. RESULTS: The result showed that there was good linear relation between the area and the concentration of psoralen、isopsoralen、isobavachin、bavachin、corylin、corylifolinin、bvachinin、psoraidin and bavachalcone within 0.4-152.0,26.4-132.0,13.6-66.0,27.2-136.0,31.2-156.0,48.8-244.0,50.4-252.0,36.0-180.0,(8.8)-44.0 ?g/mL.The average recovery of psoralen and bavachin is 98.7% and 97.6%. CONCLUSION: This method is convenient,reliable,and can be used to control the quality of Compound Buguzhi Sustained-Release Tablet.
