The aim of this study was to compare crocins in the fruit of Gardenia jasminoides and Gardenia jasminoides var. radicans. Acchrom XCharge C_(18) column(4.6 mm×250 mm, 5 μm) was used for separation, with mobile phase of acetonitrile and 0.1% formic acid for gradient elution. The detection wavelength was set at 440 nm with a flow rate of 1.0 mL·min~(-1), and the column temperature was 30 ℃. The high performance liquid chromatography(HPLC) fingerprint of crocin in Gardenia species was established by testing 20 batches of G. jasminoides and 8 batches of G. jasminoides var. radicans samples from different sources, and UHPLC-ESI-Orbitrap-MS/MS technology and reference substances were used to predict and identify the common peaks. The results showed that 20 common chromatographic peaks from the samples were selected and the structures of 16 common peaks were predicted by mass spectrum. Four common peaks(crocin Ⅰ, Ⅱ, Ⅲ, and Ⅳ) were identified by the comparison with reference substances. The content of crocin Ⅰ, Ⅱ, Ⅲ, and Ⅳ was determined simultaneously under the same chromatographic condition, and both the system suitability and the methodological investigation results met the requirements of content determination. The relative similarity of HPLC fingerprint of 28 samples to the reference fingerprint was above 0.98. The results of cluster analysis(CA) showed that G. jasminoides and G. jasminoides var. radicans were separately grouped into one group. In the 20 batches of G. jasminoides, the content of crocin Ⅰ, Ⅱ, Ⅳ, and Ⅲ was between 3.58-9.58, 0.230-1.452, 0.014 5-0.135, and 0.301-1.12 mg·g~(-1), respectively, and the total content was between 4.12-12.25 mg·g~(-1). In the 8 batches of G. jasminoides var. radicans, the content of crocin Ⅰ, Ⅱ, Ⅳ, and Ⅲ was between 5.84-11.48, 0.308-0.898, 0.010 6-0.025 5, and 0.675-1.34 mg·g~(-1), respectively, and the total content was between 6.97-13.72 mg·g~(-1). The existing results showed that there is a certain similarity between G. jasminoides and G. jasminoides var. radicans in the composition of crocin, which needs further proved by more batches of samples. The method established in this paper provides references for the quality control of G. jasminoides, G. jasminoides var. radicans, and related products.

The flower color of Dendrobium catenatum(D. officinale) tends to fade during storage. In order to clarify the influence of storage conditions on the pigment components in flowers, two conditions were applied:temperature and illumination. The contents of pigments in the D. catenatum flower were determined by UV-Vis spectrophotometry and HPLC, and the changes of them during storage were analyzed. The results showed that illumination and temperature had an effect on the pigments of D. catenatum flower during sto-rage. Illumination significantly promoted the degradation of pigments. The contents of total chlorophyll, carotenoids and anthocyanins in the light samples were significantly lower than those in the dark. The total chlorophyll, carotenoids and anthocyanins in the light samples were decreased by 46.5%, 63.4%, and 69.2% respectively. Illumination had a greater effect on fat-soluble pigments than water-soluble pigments. Among the three temperature treatments, the contents of chlorophyll, carotenoid and anthocyanin were as follows:-20 ℃>4 ℃>room temperature, it is indicated that-20 ℃ was the best temperature to maintain the stability of pigment composition. The contents of chlorophyll a, chlorophyll b, β-carotene, lutein and zeaxanthin in the light samples decreased by 34.8%, 69.0%, 72.5%, 61.6%, 36.1%, respectively. After storage for 5 months, the contents of chlorophyll, carotenoid and anthocyanin constituent at-20 ℃ was significantly higher than those at 4 ℃ and room temperature. The results show that light avoiding and low-temperature can effectively slow down the degradation of pigment components. Therefore, it is suggested that D. catenatum flower should be stored in light avoiding and low-temperature conditions in actual production and processing, which can prolong the usable time.

OBJECTIVES: This study was conducted to investigate the associations of non alcoholic fatty liver with metabolic syndrome and the serum carotenoids. METHODS: This study was conducted in a general hospital in South Korea from November, 2004 to August, 2005. The study subjects were 350 sampled persons who were aged from 40 years and older (males: 180, females: 170). They were grouped into the normal, mild and severe groups according to fat accumulation in their livers, as determined by ultrasonography. We analyzed the association between non alcoholic fatty liver and metabolic syndrome by multiple logistic regression analysis and we analyzed the association between non alcoholic fatty liver and the serum carotenoids by a general linear model(ANCOVA). RESULTS: After adjustment for the effect of potential covariates, the prevalence of metabolic syndrome was associated with fat accumulation in the liver (p trend <0.001). If the odds ratio of normal group is 1.00, then that of the mild group is 2.80 (95% C.I=1.17-6.71) and that of the severe group is 7.29 (95% C.I=2.76-19.30). The prevalence of metabolic alterations fitting the criteria of metabolic syndrome, according to the class of fat accumulation in the liver, was significantly increased, except for criteria of high blood pressure, a large waist circumference and low HDL (high density lipoprotein) cholesterol level (p trend <0.001). The level of serum beta-carotene was decreased according to the class of fat accumulation in the liver (p trend=0.036), but the levels of serum alpha-carotene, lycopene, bata-cryptoxanthin and lutein were not decreased. CONCLSIONS: This study shows that non alcoholic fatty liver was associated with metabolic syndrome and with the serum beta-carotene level.

To explore the influence of low light on the synthesis of carotenoids, chlorophyll and the adaptability of transgenic plants with tomato Solanum lycopersicon L. GGPS2 gene, we constructed a vector containing a GGPS2 gene with green fluorescent protein (GFP) as report gene under the control of a cauliflower mosaic virus 35S promoter and introduced it into tobacco Nicotiana tabacum L. cv. Wisconsin 38 by Agrobacterium tumefaciens-mediated transformation. PCR analysis of the DNA from kanamycin resistant tobacco indicated that the transgenic tobacco containing the nptII gene, SlaGGPS2 gene and without contamination of Agrobacterium. We also detected the root tip of kanamycin resistant tobacco showing characteristic fluorescence. The contents of carotenoid, chlorophyll and photosynthesis of transgenic tobacco increased in comparison with wild tobacco after low light treatment. In addition, leaf mass per unit area, total dry weight, ratio of root to shoot in transgenic tobacco were all higher than that of the wild tobacco, which proved that the transgenic tobacco could increase the accumulation of biomass and promote it transport to root. The transgenic tobacco with SlaGGPS2 gene can increase the contents of carotenoid, chlorophyll, enhance the photosynthetic rate, promote the biomass accumulation and its distribution to root. Hence, the transgenic tobacco with SlaGGPS2 gene had increased low light tolerance and the SlaGGPS2 gene maybe can be used in other crops.

To optimize the technology of Gardeniae Fructus processed with ginger juice,establish fingerprints and simultaneously determine seven compounds( geniposidic acid,chlorogenic acid,genipin-1-β-D-gentiobioside,geniposide,rutin,crocin Ⅰ,and crocin Ⅱ) by using ultra high performance liquid chromatography( UPLC). Waters ACQUITY UPLC BEH C18( 2. 1 mm×50 mm,1. 7μm) column was used with acetonitrile and 0. 1% formic acid solution as mobile phase for gradient elution at the flow rate of 0. 4 m L·min-1. The data was comprehensively processed and analyzed with similarity evaluation,principal component analysis( PCA) and partial least squares discriminant analysis( PLS-DA) methods. Twenty common peaks were identified in this study,and the similarity of samples was over 0. 97. The results of PCA and PLS-DA showed that there were differences in chemical compositions and contents between the raw Gardeniae Fructus and those processed with ginger juice,with 9 potential differentiated chromatographic peaks. After being processed with ginger juice,the contents of chlorogenic acid,crocin Ⅰ and crocin Ⅱ were less than before and the contents of other four compositions were higher than before. The optimized preparation for Gardeniae Fructus processed with ginger juice was stable and feasible. The methods of UPLC fingerprints and simultaneous determination of seven components can be effectively carried out to distinguish Gardeniae Fructus and Gardeniae Fructus processed with ginger juice.
