1.Qualitative and Quantitative Analysis of Flower Pigments in Chocolate Cosmos, Cosmos atrosanguineus, and its Hybrids.
Amamiya K, Iwashina T. Nat Prod Commun. 2016 Jan;11(1):77-8.
Two major anthocyanins, cyanidin 3-O-glucoside and 3-O-rutinoside, were isolated from the black flowers of Cosmos atrosanguineus cultivar 'Choco Mocha', together with three minor anthocyanins, cyanidin 3-O-malonylglucoside, pelargonidin 3-O-glucoside and 3-O-rutinoside. A chalcone, butein 4'-O-glucoside and three minor flavanones were isolated from the red flowers of C. atrosanguineis x C. sulphureus cultivar 'Rouge Rouge'. The anthocyanins and chalcone accumulation of cultivar 'Choco Mocha' and its hybrid cultivars 'Brown Rouge', 'Forte Rouge', 'Rouge Rouge' and 'Noel Rouge' was surveyed by quantitative HPLC. Total anthocyanins of black flower cultivars 'Choco Mocha' and 'Brown Rouge' were 3-4-folds higher than that of the red flower cultivar 'Noel Rouge'. On the other hand, total chalcone of 'Noel Rouge' was 10-77-folds higher compared with those of other cultivars, 'Brown Rouge', 'Forte Rouge' and 'Rouge Rouge'. It was shown that the flower color variations from red to black of Chocolate Cosmos and its hybrids are due to the difference in the relative amounts of anthocyanins and chalcone.
2.Fluorescence study on the interaction of human serum albumin with Butein in liposomes.
Toprak M1. Spectrochim Acta A Mol Biomol Spectrosc. 2016 Feb 5;154:108-13. doi: 10.1016/j.saa.2015.10.023. Epub 2015 Oct 24.
The interaction of Butein with human serum albumin in L-egg lecithin phosphatidycholine (PC) liposome has been investigated by fluorescence and absorption spectroscopy. The results of the fluorescence measurement indicated that Butein effectively quenched the intrinsic fluorescence of HSA via static quenching. The Stern–Volmer plots in all the liposome solutions showed a positive deviation from the linearity. According to the thermodynamic parameters, the hydrophobic interactions appeared be the major interaction forces between Butein and HSA. The effect of Butein on the conformation of HSA was also investigated by the synchronous fluorescence under the same experimental conditions. In addition, the partition coefficient of the Butein in the PC liposomes was also determined by using the fluorescence quenching process. The obtained results can be of biological significance in pharmacology and clinical medicine.
3.Butein inhibits cell proliferation and induces cell cycle arrest in acute lymphoblastic leukemia via FOXO3a/p27kip1 pathway.

Acute lymphoblastic leukemia (ALL) is a common hematological malignancy characterized by the uncontrolled proliferation of leukemia cells in children. Discovering and developing effective chemotherapeutic drugs are needed for ALL. In this study, we investigated the anti-leukemic activity of butein and its action mechanisms in ALL. Butein was found to significantly suppress the cellular proliferation of ALL cell lines and primary ALL blasts in a dose-dependent manner. It also induced cell cycle arrest by decreasing the expression of cyclin E and CDK2. We also found that butein promoted nuclear Forkhead Class box O3a (FOXO3a) localization, enhanced the binding of FOXO3a on the p27kip1 gene promoter and then increased the expression of p27kip1. Moreover, we showed that FOXO3a knockdown significantly decreased the proliferation inhibition by butein, whereas overexpression of FOXO3a enhanced the butein-mediated proliferation inhibition. However, overexpression of FOXO3a mutation (C-terminally truncated FOXO3a DNA-binding domain) decreased the proliferation inhibition by butein through decreasing the expression of p27kip1.
4.[A new bisabolane-type sesquiterpenoid from Coreopsis tinctoria].
Liu JJ, Yang YJ, Zhu YD, Li GZ, Huang WH, Guo BL. Zhongguo Zhong Yao Za Zhi. 2015 Jun;40(11):2132-7.
To study the chemical constituents of the inflorescences of Coreopsis tinctoria from Xinjiang, isolation and purification of constituents were carried out by column chromatography on macroporous resin (D101) , MCI gel, MDS gel, silica gel, Sephadex LH-20 and semi-preparative HPLC. The structures of the compounds were identified by physicchemical properties and spectral data analysis. Fourteen compounds were isolated and identified as coretinterpenoid A (1), coretinphenol (2), quercetin (3), quercetin-3-O-β-glucopyranoside (4), luteolin (5), taxifolin (6), 7, 3', 5'-trihydroxyflavanone (7), isookanin (8), isookanin-7-O-β-D-glucopyranoside (9), 5, 7, 3', 5'-tetrahydroxyflavanone-7-O-β-D-glucopyranoside (10), butein (11), okanin (12), sulfuretin (13), and linocinnamarin (14). Compound 1 was a new isabolane-type sesquiterpenoid and compounds 4, 10 and 13 were isolated from this plant for the first time.
