Studies in Natural Products Chemistry
Natural products in the plant and animal kingdom offer a huge diversity of chemical structures that are the result of biosynthetic processes that have been modulated over the millennia through genetic effects. With the rapid developments in spectroscopic techniques and accompanying advances in high-throughput screening techniques, it has become possible to isolate and then determine the structures and biological activity of natural products rapidly, thus opening up exciting new opportunities in the field of new drug development to the pharmaceutical industry. The series also covers the synthesis or testing and recording of the medicinal properties of natural products. - Describes the chemistry of bioactive natural products - Contains contributions by leading authorities in the field - A valuable resource for natural products and medicinal chemistry
Phytopharmaceuticals
Medicinal plants contain a variety of bioactive compounds, (also referred to as phytochemicals). in the leaves, stems, flowers and fruits. This book covers these bioactive compounds, their available sources, how the bioactive molecules are isolated from the plants, the biochemistry, structural composition and potential biological activities. Also discussed are the pharmacological aspects of medicinal plants, phytochemistry and biological activities of different natural products, ethnobotany and medicinal properties, as well as a novel dietary approach for various disease management and therapeutic potential. The importance of phytopharmaceutical of plants and potential applications in the food and pharma industries is highlighted.
Reviews on Biomarker Studies in Aging and Anti-Aging Research
Using both epidemiological and model organism approaches, we have gained new insights into the physiological and molecular aspects of aging, which has led to significant advancements in potential anti-aging strategies. Reviews on Biomarker Studies in Aging and Anti-Aging Research presents a series of reviews in various aspects of aging and age-related disease research along with several methods which have shown progress as potential anti-aging approaches. The book is aimed at researchers in the areas of aging and chronic disease, as well as to clinical scientists, physicians and major drug companies. It provides important information on disease mechanisms, and each chapter is presented in the context of the aging process, specific chronic diseases or different therapeutic areas.
Studies in Natural Products Chemistry
Many cosmetics that are marketed nowadays often contain antioxidants as the active ingredients. It is known that oxidation reactions could produce free radicals, which can start chain reactions that will damage skin cells. Increasing the amount of free radicals could initiate the wrinkling, photoaging, elastosis, drying, and pigmentation of the skin. Topical antioxidants could terminate the chain reactions by removing the free radical intermediates and inhibit other oxidation reactions by being oxidized themselves; this could defend the skin against the environmental stress caused by free radicals. It is well known that plants can produce natural antioxidant compounds that could control the ...
Majalah Trubus Edisi Maret 2021
Virus korona yang amat kecil, berdampak amat besar di berbagai sektor kehidupan. Hingga pertengahan Februari 2021, jumlah penderita akibat korona di Indonesia mencapai 1,19 juta. Setelah setahun pandemi virus korona, belum juga ada tanda-tanda melandai. Kasus harian melonjak hingga 300-an orang. Latar belakang itulah yang mendorong redaksi mengulas pemanfaatan beragam herbal seperti rimpang jahe, daun kayuputih, dan daun sambilata untuk mengatasi virus korona. Pemilihan herbal itu berdasarkan hasil riset ilmiah berbagai lembaga. Jadi, bukan sekadar fakta empiris berdasarkan pengalaman seseorang yang kondisinya terus membaik setelah mengonsumsi herbal tertentu. Keberadaan riset sebuah keharusan untuk membuktikan khasiat tanaman obat. Selain itu, dosis dan frekuensi konsumsi, bahkan efek samping pun lebih terukur. Masyarakat relatif mudah memperoleh tanaman obat dan mengolahnya.
Strategic Affiliate Marketing
Rather than arguing the rights and wrongs in absolute terms, this book presents a strategy for engaging in affiliate marketing. The authors also examine what considerations should be taken into account before doing so, as well as investigating how to optimise resources once fully active in this area.".
The Journeys 3
Batas akan tetap menjadi batas, saat tak ada yang benar-benar berani menyeberanginya. Seperti halnya kita menamai utara sebagai utara, karena tak ada yang pernah bertanya kenapa. Jarak akan tetap menjadi jarak, saat tak ada yang memulai langkah untuk menyudahinya. Kita hanya menduga-duga, sebelah langit mana yang berwarna lebih merah. Dan, perjalanan hanya akan menjadi perjalanan, saat tak ada yang sudi menceritakan kisah yang menyertanya. Maka, temuilah, lewati batas, tuntaskan jarak. Ceritakan—setidaknya kepada diri sendiri, tentang jawaban yang kita temui. *** Inilah kisah perjalanan yang akan membuat kita kembali kepada sesuatu yang paling dekat, sejauh apa pun kita melangkah pergi. Sebuah perjalanan ‘ziarah’; mengunjungi diri sendiri. -GagasMedia-
Misconceptions in Chemistry
Over the last decades several researchers discovered that children, pupils and even young adults develop their own understanding of "how nature really works". These pre-concepts concerning combustion, gases or conservation of mass are brought into lectures and teachers have to diagnose and to reflect on them for better instruction. In addition, there are ‘school-made misconceptions’ concerning equilibrium, acid-base or redox reactions which originate from inappropriate curriculum and instruction materials. The primary goal of this monograph is to help teachers at universities, colleges and schools to diagnose and ‘cure’ the pre-concepts. In case of the school-made misconceptions it will help to prevent them from the very beginning through reflective teaching. The volume includes detailed descriptions of class-room experiments and structural models to cure and to prevent these misconceptions.
High-Performance Thin-Layer Chromatography (HPTLC)
The present edited book is the presentation of 18 in-depth national and international contributions from eminent professors, scientists and instrumental chemists from educational institutes, research organizations and industries providing their views on their experience, handling, observation and research outputs on HPTLC, a multi-dimensional instrumentation. The book describes the recent advancements made on TLC which have revolutionized and transformed it into a modern instrumental technique HPTLC. The book addresses different chapters on HPTLC fundamentals: principle, theory, understanding; instrumentation: implementation, optimization, validation, automation and qualitative and quantitative analysis; applications: phytochemical analysis, biomedical analysis, herbal drug quantification, analytical analysis, finger print analysis and potential for hyphenation: HPTLC future to combinatorial approach, HPTLC-MS, HPTLC-FTIR and HPTLC-Scanning Diode Laser. The chapters in the book have been designed in such away that the reader follows each step of the HPTLC in logical order.
