homogenate extraction of Gardenia yellow pigment from Gardenia jasminoides ellis fruit using response surface methodology
Journal of Food Science and Technology-mysore, 2014Co-Authors: Yili Mang, Fengqiong Shen, Weike SuAbstract:Homogenate extraction technology was developed for extraction of Gardenia yellow pigment from Gardenia jasminoides Ellis fruit. The operating parameters affecting the color value of Gardenia yellow pigment were studied on the basis of a Box-Behnken design and response surface methodology. Results showed that the optimum extraction conditions were as follows: extraction time 41 s, ethanol concentration 50 %, ratio of liquid to material 15:1 (mL:g) and particle size 1.7 mm. Under the optimum condition, the experimental color value was 52.37 g−1, which was in keeping with the predicted one. Compared with the heat extraction method, the color value of Gardenia yellow pigment of homogenate extraction was higher and the extraction time was shorter. Homogenate extraction method is an ideal means for extraction of Gardenia yellow pigment from Gardenia jasminoides Ellis fruit.

Ultrasound-assisted extraction of geniposide from Gardenia jasminoides.
Ultrasonics Sonochemistry, 2012Co-Authors: Xin-sheng Wang, Shi-lin Dai, Rong Chen, Ying ShaoAbstract:Abstract Fructus Gardeniae (Zhizi), one of commonly-used traditional Chinese medicines, is derived from the ripe fruit of the evergreen shrub, Gardenia jasminoides Ellis, and is an ingredient of many traditional Chinese preparations, and has numerous pharmacological actions. Geniposide is the important bioactive element derived from F. Gardeniae. This study established optimum conditions and method of ultrasound-assisted extraction for geniposide from F. Gardeniae by exploring the different experimental parameters, such as type of solvent, ratio of solid/liquid, extraction temperature and extraction time. The data gained from this study is important to further extract and apply the geniposide and is also a significant reference to extract the bioactive compounds from plant materials by the ultrasound-assisted method.

Optimization of ultrasound-assisted extraction of Gardenia fruit oil with bioactive components and their identification and quantification by HPLC-DAD/ESI-MS2
Food & Function, 2015Co-Authors: Xiaoshuang Cai, Zhenzhou Zhu, Rui Zhang, Zhiwei Liu, Gang Liu, Ying Guo, Jun YangAbstract:Compounds in Fructus Gardeniae have been shown to possess a wide array of biological activities. However, Gardenia oil extracted from its fruit is less reported and its composition remains uncertain. To completely characterize lipophilic compounds in Gardenia oil, three conventional extraction (CE) and ultrasound-assisted extraction (UAE) methods were investigated. The oil extraction yield obtained by UAE was 51.8% higher than that acquired by cold-pressed extraction (CPE). The fatty acid profile in UAE oil with different solvents was characterized by GC-MS. Petroleum ether was observed to be an ideal solvent with 8.59% extraction yield and 78.88% recovery rate and with a ratio of 3.11 of unsaturated fatty acids to saturated fatty acids. Response surface methodology (RSM) with Box–Behnken Design (BBD) was applied to optimize conditions in UEA of oil to maximize extraction yield. Furthermore, the bioactive components in oil extracted by UAE were qualitatively identified and quantified by HPLC-DAD/ESI-MS2 and HPLC-DAD analysis. The eight compounds in Gardenia oil, including geniposide, trans/cis-crocin-1, crocin-2, crocin-3, crocin-4, and trans/cis-crocetin, were structurally revealed. The corresponding transfer rates of the bioactive components showed that the lipophilic trans/cis-crocetin could be completely transferred from fruit to oil, with the highest concentration of 11.38 μg g−1 oil among all compounds quantified. These findings could deliver potential application to a large-scale production of functional Gardenia oil whose bioactive components possess health benefits.
