Objective To establish a thin layer Chromatograph-Fluores cent method for the determination of karanjin in Radix of Fofdia caulifora. Methods Anhydrous-EtOH is solution, thin-sheet is silica gel, expanding solution is Benzene-EtoAc (8.5∶1.5), with excitation wavelength at 355 nm and emission wavelength at 428 nm. Results The average recovery of karanjin was 99.14% and RSD was 1.94% (n =5). There is a good linear relationship within the range of 0.138~0.69 ?g of karanjin. Conclusion The method is convenient, sensitive, accurate and reproducible, and can be used the quality control of the Radix of Fofdia caulifora.

Objective To extract and determine the total flavonoids in Fordia cauliflora. Methods Total flavonoids in Fordia cauliflora were extracted by microwave technology and determined by colorimetry. Results Total flavonoids in Fordia cauliflora was 1.12%, and recovery rate was 99.5%, RSD was 2.36%. Conclusion The method is convenient, accurate and can be used for the extraction of total flavonoids in Fofdia caulifora.

Object To study the chemical constituents of the dried root of Fordia cauliflora Hemsl which is indigenous to Guangxi and commonly used in traditional medicine of Zhuang and Yao nationalities Methods The constituents were isolated with column chromatography and their structures were elucidated on the basis of physicochemical data and spectral analysis Results The three constituents were isolated and identified as 2 [3 methoxyphenyl] 4H furo[2,3 h] 1 benzoyran 4 one (Ⅲ), 3 methoxy 2 [3 hydroxyphenyl] 4H furo [2, 3 h] 1 benzopyran 4 one (Ⅳ) and pinnatin (Ⅴ) Conclusion The all of them are isolated from this plant for the first time Compound Ⅲ,Ⅳ are new and tentatively named as cauliflorin A and cauliflorin B

Objective To explore the association between lipid profiles and left ventricular hypertrophy in a Chinese general population. Methods We conducted a retrospective observational study to investigate the relationship between lipid markers [including triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL-cholesterol, apolipoprotein A-I, apolipoprotein B, lipoprotein[a], and composite lipid profiles] and left ventricular hypertrophy. A total of 309,400 participants of two populations (one from Beijing and another from nationwide) who underwent physical examinations at different health management centers between 2009 and 2018 in China were included in the cross-sectional study. 7,475 participants who had multiple physical examinations and initially did not have left ventricular hypertrophy constituted a longitudinal cohort to analyze the association between lipid markers and the new-onset of left ventricular hypertrophy. Left ventricular hypertrophy was measured by echocardiography and defined as an end-diastolic thickness of the interventricular septum or left ventricle posterior wall > 11 mm. The Logistic regression model was used in the cross-sectional study. Cox model and Cox model with restricted cubic splines were used in the longitudinal cohort. Results In the cross-sectional study, for participants in the highest tertile of each lipid marker compared to the respective lowest, triglycerides [odds ratio (OR): 1.250, 95%CI: 1.060 to 1.474], HDL-cholesterol (OR: 0.780, 95%CI: 0.662 to 0.918), and lipoprotein(a) (OR: 1.311, 95%CI: 1.115 to 1.541) had an association with left ventricular hypertrophy. In the longitudinal cohort, for participants in the highest tertile of each lipid marker at the baseline compared to the respective lowest, triglycerides [hazard ratio (HR): 3.277, 95%CI: 1.720 to 6.244], HDL-cholesterol (HR: 0.516, 95%CI: 0.283 to 0.940), non-HDL-cholesterol (HR: 2.309, 95%CI: 1.296 to 4.112), apolipoprotein B (HR: 2.244, 95%CI: 1.251 to 4.032) showed an association with new-onset left ventricular hypertrophy. In the Cox model with forward stepwise selection, triglycerides were the only lipid markers entered into the final model. Conclusion Lipids levels, especially triglycerides, are associated with left ventricular hypertrophy. Controlling triglycerides level potentiate to be a strategy in harnessing cardiac remodeling but deserve to be further investigated.
