Introduction. There is steady upward trend in demand for herbal formulation necessitates the expansion of their range. Recent studies have shown that one of the promising research direction is the development of herbal collection based water-soluble dry extracts. Pectoral species № 4 is one of the most popular among multi-component herbal preparations on the Russian pharmaceutical market. Experimental samples of a dry extract were obtained on the collection basis. According to literature, phenolic compounds predominate both in individual components and pectoral species № 4. Therefore, the end-to-end standardization of the collection and its dry extract by the content of the substances seems to be relevant.Aim. The present study was performed to examine the dry extract phenolic compounds composition, as well as, to search for marker compounds for the end-to-end standardization of pectoral species № 4 and dosage forms based on it.Materials and methods. The composition and content of phenolic complex were studied by HPLC with UV detection in pectoral species № 4 and its dry extract. Detection was performed at wavelengths of 350, 300, 270, 210 nm. The quantitative content (%) of the identified compounds was determined by an external standard method.Results and discussion. HPLC-analysis revealed 58 compounds in pectoral species № 4 and 34 in the extract. Rutin, arbutin, liquraside, liquiritin, quercetin, chlorogenic, caffeic and gallic acid have been identified in all study objects; their quantitative content varied within a range of 0,001−0,910%.Conclusion. Arbutin, rutin and chlorogenic acid have been proposed as marker compounds.

Freedom of the Press is the right to express, disseminate ideas, organize, and so forth. Freedom of the Press is based on the provisions made by the Press Council called the Journalistic Code of Ethics. The Journalistic Code of Ethics is the professional ethics of journalists. As the party that disseminates information to the public, journalists need to practice the provisions of the Journalistic Code of Ethics which consists of 11 articles, because various news reports that journalists report should have an impact on society. Then, one of the news that received more attention from the public, namely regarding the relocation of the Indonesian capital. At that time, the news received various responses from various parties. Therefore, various media are aggressively producing news related to this, such as Liputan6.com. In this study, the Journalistic Code of Ethics analyzed with the news included article 1, 2, and 3. The purpose of this study was to determine the application of the Journalistic Code of Ethics in reporting the removal of the Indonesian Capital City on Liputan6.com. Theories used include news reporting and the Journalistic Code of Ethics. Then, for the research method used, namely quantitative content analysis using coding sheets to process, and analyze the data. The results of this study indicate Liputan6.com has implemented a Journalistic Code of Ethics, although of the 55 news samples there are still 19 news that do not meet the element of balance.Kebebasan pers merupakan hak untuk berekspresi, menyebarluaskan gagasan, dan berorganisasi. Kebebasan pers dilandasi oleh ketentuan yang dibuat Dewan Pers yang disebut Kode Etik Jurnalistik. Kode Etik Jurnalistik adalah etika profesi wartawan. Sebagai pihak yang menyebarkan informasi kepada khalayak, jurnalis perlu mempraktikan ketentuan Kode Etik Jurnalistik yang terdiri dari 11 pasal. Hal ini karena berbagai berita yang jurnalis laporkan akan memberi dampak pada masyarakat. Salah satu pemberitaan yang mendapatkan perhatian lebih dari masyarakat, yaitu mengenai pemindahan ibu kota Indonesia. Pada saat itu, kabar tersebut mendapatkan berbagai respon dari berbagai pihak. Oleh karena itu, berbagai media gencar dalam memproduksi berita terkait hal tersebut, salahsatunya Liputan6.com. Pada penelitian ini, Kode Etik Jurnalistik yang dianalisis dengan pemberitaan tersebut, antara lain pasal 1, 2, dan 3. Tujuan dari penelitian ini ialah untuk mengetahui penerapan Kode Etik Jurnalistik pada pemberitaan pemindahan Ibu Kota Indonesia di Liputan6.com. Teori yang digunakan diantaranya pemberitaan, dan Kode Etik Jurnalistik. Metode penelitian yang dipakai yakni analisis isi kuantitatif dengan memakai lembar codinguntuk mengolah, dan menganalisis datanya. Hasil dari penelitian ini menunjukan Liputan6.com sudah menerapkan Kode Etik Jurnalistik, meskipun dari 55 sampel berita masih terdapat 19 berita yang tidak memenuhi unsur keberimbangan.

The present study examines the relevance and framing of Corporate Social Responsibility in the mass media. Challenged by the ethically (over)loaded issue of responsibility, communication studies are searching for a new understanding of framing to investigate phenomena of new economic values like Corporate Social Responsibility in public discourses. For the quantitative content analysis put forward herein, frames are described as footprints of diverse positions, which determine a given public discourse. The longitudinal analysis of 26 German-speaking newspapers in Germany, Austria, and Switzerland between 1999 and 2008, a phase where CSR was aligned in business practices and CSR communication established in public discourses, aims at identifying CSR-frames as well as inquiring into the existence of a public discourse about CSR. The results show that there is no discourse on CSR itself. Instead of the assumed multiple issue-specific frames, CSR itself is (ab)used as a masterframe or “buzz word” in economic discourses.

Pineapple peel still contains an important amount of phenolic compounds and vitamins with valuable antioxidant activity. In this way, the aim of this study was the recovery of the bioactive compounds from pineapple peel using environmentally friendly and low-cost techniques, envisaging their application in food products. From the solid-liquid extraction conditions tested, the one delivering an extract with higher total phenolic content and antioxidant capacity was a single extraction step with a solvent-pineapple peel ratio of 1:1 (w/w) for 25 min at ambient temperature, using ethanol-water (80–20%) as a solvent. The resulting extract revealed a total phenolic content value of 11.10 ± 0.01 mg gallic acid equivalent (GAE)/g dry extract, antioxidant activity of 91.79 ± 1.98 µmol Trolox/g dry extract by the DPPH method, and 174.50 ± 9.98 µmol Trolox/g dry extract by the FRAP method. The antioxidant rich extract was subjected to stabilization by the spray drying process at 150 °C of inlet air temperature using maltodextrin (5% w/w) as an encapsulating agent. The results showed that the antioxidant capacity of the encapsulated compounds was maintained after encapsulation. The loaded microparticles obtained, which consist of a bioactive powder, present a great potential to be incorporated in food products or to produce bioactive packaging systems.
