2.Volatile constituents in the flowers of Elsholtzia argyi and their variation: a possible utilization of plant resources after phytoremediation.
Journal of Zhejiang University. Science. B 2005;6(2):91-95
Phytoremediation effectiveness and remediation costs are driving factors of this project. Full utilization of plant resources after their being used for phytoremediation is an unsolved problem. GC/MS technique was used to investigate the volatiles of the flowers from Elsholtzia argyi (PFE1: Purple Flower Elsholtzia) and their variation (WFE: White Flower Elsholtzia), naturally growing in Pb/Zn mined area, and Elsholtzia argyi (PFE2: Purple Flower Elsholtzia), naturally growing in Jiuxi uncontaminated agriculture soil. Seventeen compounds constituting 86.88% of total essential oils were identified in PFE1, with 2,6-octadienoic acid,3,7-dimethyl-methyl ester being the main constituent (63.30%). Sixteen compounds accounting for 95.32% of total essential oils were identified in WFE, with caryophyllene being the main component (55.02%). Compared to PFE1, PFE2 contains lower level of 2,6-octadienoic acid,3,7-dimethyl-methyl ester (31.76%), which is the main constituent in the total essential oils of PFE2. Caryophyllene is the main ingredient of flavor. Elsholtzia ketone was identified in all the three Elsholtzia plants. It can be concluded that the selected Elsholtzia argyi plants can be exploited on their versatile uses as fragrances and antiseptics due to the perfume ingredient and antibacterial components existing in their essential oils.

OBJECTIVETo observe the therapeutic effects of Berberine Capsule (BC) on patients with mild hyperlipidemia.
METHODSTotally 102 mild hyperlipemia patients were recruited. All patients were suggested to have proper diet and physical activity as basic therapy for 1 month of run-in period. Totally 97 patients completed it. Then they were randomly assigned to the berberine group (the treatment group, 49 cases) and the placebo group (the control group, 48 cases). Patients in the treatment group took BC 300 mg, while those in the control group took placebo 300 mg, thrice per day for 3 successive months. Then placebos and BC were interrupted for 2 months (as washout period). All subjects received only diet control and physical activity during washout period. After washout period, placebos and BC were re-administered to all patients in the same way for 3 months. Body mass index (BMI), fasting plasma glucose (FPG), TG, TC, LDL-C, and HDL-C were assessed after run-in period, washout period, at month 1, 2, 3 after the first therapy, at month 1, 2, 3 after second treatment, respectively.
RESULTSCompared with the end of run-in period, TG, TC, and LDL-C decreased, and HDL-C increased in the treatment group (P < 0.05) after first 3 months of treatment. Compared with 3 months after the first therapy, TG, TC, and LDL-C increased and HDL-C decreased in the treatment group after washout period (P < 0.05). Compared with the end of wash- out period, TC and LDL-C decreased in the treatment group at month 2 after second treatment (P < 0.05); TG, TC, and LDL-C decreased (P < 0.01, P < 0.05), and HDL-C increased (P < 0.05) at month 3 after second treatment. Compared with the control group at month 3 after second treatment, TG, TC, and LDL-C all decreased, and HDL-C increased in the treatment group (all P < 0.05).
CONCLUSIONBC was effective in improving blood lipid level in mild hyperlipidemia patients.

A solution with different Cu supply levels was cultured to investigate gama-aminobutyric acid (GABA) accumulation in Elsholtzia splendens, a native Chinese Cu-tolerant and accumulating plant species. Increasing Cu from 0.25 to 500 micromol/L significantly enhanced levels of GABA and histidine (His), but considerably decreased levels of aspartate (Asp) and glutamate (Glu) in the leaves. The leaf Asp level negatively correlated with leaf Cu level, while leaf GABA level positively correlated with leaf Cu level. The leaf Glu level negatively correlated with leaf GABA level in Elsholtzia splendens. The depletion of leaf Glu may be related to the enhanced synthesis of leaf GABA under Cu stress.

The active components from Centipeda minima were extracted by water or ethanol, and identified by FTIR spectroscopy and UV-visible spectrophotometer. The molluscicidal effect of aqueous extract and ethanol extract from Centipeda minima against Oncomelania hupensis was determined as referring to the WHO guidelines for laboratory molluscicidal test. Treated with over 2.0 g/L aqueous extract and ethanol extract for five days, the mortality of O. hupensis was up to 100%, and their LC50 for snails was 0.50 g/L and 0.62 g/L, respectively. The molluscicidal activity of aqueous extract was higher than that of ethanol extract. The main components of aqueous extract and ethanol extract were sesquiterpens lactones and sterols.

?Proliferative diabetic retinopathy ( PDR ) is a group of disease characterized by neovascular disease complication of diabetes mellitus. Neovascular diseases of eye are one of the major causes of blindness of the world. Recent studies showed that vascular endothelial growth factor ( VEGF) and pigment epithelium-derived factor ( PEDF ) are now accepted as the key cytokine in the development of diabetic retinopathy. Recent progress in the investigation of VEGF and PEDF of PDR are summarized in this review.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.

This study aims to investigate the relationship between odor and contents of the chemical compounds in Lonicera japonica, including chlorogenic acid, galuteolin and polyphenols. High performance liquid chromatography (HPLC) was applied to determine the contents of chlorogenic acid and galuteolin in L. japonica. The ponptent of polyphenols was determined by UV-Vis Spectrophotometry. Electronic nose was used to extract and measure the odor of L. japonica. Then SPSS 17.0 software was employed for data processing. There is a significant positive correlation between the comprehensive index value of aroma and the contents of chlorogenic acid and polyphenols. The regression equations have been established. However, the relationship between the comprehensive index value and the content of galuteolin is not obvious. This is proof that the odor of L. japonica has close connection with the chemical compounds. Therefore, this research offered a new method for initially determine or predict the content of the chemical composition in L. japonica,
