Flavonoids ofGoebelia pachycarpa
The following substances were isolated and were identified on the basis of chemical and spectral characteristics: kaempferol, quercetin, and genistein. A fourth compound C26H2sO14 (I), mp 125-128°C, [a]~ 2 --34.4 ± 2 ° (c 1.05 MeOH) was an isoflavone derivative according to its UV spectrum (%maxethanol, nm: 263, 328 sh; log g 4.56, 3.73) [i]. Its IR spectrum contained absorption bands at (cm -I) 3527-3295 (OH groups), 1660 (C=O of a a-pyrone), 1622, 1589 (aromatic ~ bonds), and 1098-1040 (C O vibrations of glycosides).
Stoffwechselprodukte von Mikroorganismen 6‐Chlorgenistein und 6,3′‐Dichlorgenistein. 164. Mitteilung
Metabolites from Microorganisms, 6-Chlorogenistein and 6,3′-Dichlorogenistein



A strain of Streptomyces griseus produced chlorinated metabolites in media containing soybean meal. Two of these metabolites were isolated together with a chlorine free compound which could be identified as the isoflavone genistein (I) by its spectral properties and by comparison with an authentic sample. By NMR. and mass spectroscopy the chlorinated compounds were shown to be 6-chlorogenistein (II) and 6,3′-dichlorogenistein (III).



The 7-glucoside of genistein is a constituent of soybean meal; it is hydrolysed and chlorinated by Streptomyces griseus.
La participacion de los stakeholders en las iniciativas de branding del hospital en las redes sociales: una propuesta de modelo para construir marcas colectivas
Introduction : All health organizations face many managerial and economic challenges such as the consolidation of private and international hospitals, the increasingly interest of society for health education issues or the development of telemedicine. In this framework, many organizations prioritize social media as the main corporate communication tool for building a reputed brand in a collective way along with stakeholders. Objectives : This paper aims to identify a communication model allowing hospitals to efficiently apply branding initiatives on social media in order to build a brand in a collective way with stakeholders. Methodology : We carried out a literature review about corporate communication, health communication, branding and social media; and, then, we proposed the PET Model for Branding Hospitals on Social Media. Results and Conclusion : We conclude that hospitals should create a multidisciplinar corporate communication department, implement management initiatives for allowing health professionals have more time for using social media and integrate health education and patient’s empowerment in every communication initiative.
