Background Around 80% of human population in the world relies on herbal or phytomedicines for their primary health care needs. The treatment of many diseases and disorders with phytomedicines is considered and observed as very safe with no or minimal side effects. Many medicinal plants and their preparations are practised at home as remedies for treating and preventing various diseases and disorders. For example, medicinal plants and their crude parts such as tulsi, neem, turmeric and ginger are used to cure or treat several common ailments, out of which Curcuma zedoaria Rosc commonly known as white turmeric is one of the important crude drugs belonging to Zingiberaceae family and genus Curcuma. Traditionally, it has been reported to possess many biological activities been used for many therapeutic actions due to the presence of wide range of phytoconstituents in it. The main objectives of the present work are to carry out extensive review on its chemical, pharmacological and biological activities of plant. Main body In the present review article, extensive data on its chemical, pharmacological and biological activities have been collected from various online sources including indexing sites such as Web of Science, Scopus, PubMed and Research Gate and presented. Various articles published in indexed journals and other databases have been collected and reviewed systematically. Conclusion The present review investigation is very much helpful for researchers and readers to collectively have valuable information on chemistry, pharmacology and biological effects of Curcuma zedoaria Rosc. The present investigation concludes that the white turmeric is found to possess complex range of phytoconstituents such as curcumin, ethyl p-methoxycinnamate, β-turmerone, β-eudesmol, zingiberene, dihydrocurcumin, furanodiene, α-phellandrene, 1–8 cineole, β-elemense and germacrone. Due to the presence of wide range of phytoconstituents, plants have been reported for its diverse biological activities.

Background Herbal medicines and their preparations have been mostly used since from thousands of years in all developing and developed countries in the primary health care of society and community. Flavonoids are the class of polyphenolic compounds, which are mainly distributed throughout the plant kingdom. Quercetin is a flavonoid which shows major pharmacological activities and effectively used for the management and treatment of various diseases and disorders. Many herbal medicines and their formulations containing Quercetin are available in market and hence quality control of Quercetin in is very important and essential in manufacturing industries Main body of the abstract We have reviewed various scientific research published on quality control analysis and standardization of Quercetin in its isolated form, extract or any other herbal or polyherbal preparation. We have mainly focused on the spectroscopic and chromatographic methods for qualitative and quantitative analysis of Quercetin and they were comprehensively presented in the present review work. Short conclusion The present review concludes that the spectroscopic and chromatographic methods play great role in the quality control and standardization of Quercetin in its isolated form, extract and in its herbal and polyherbal preparation.

Many free radicals are generates in the human body due to metabolic processes and in order to counteract the harmful effects of these antioxidants, human body has a complex system of natural enzymatic and non-enzymatic antioxidant defenses or mechanisms. These free radicals are mainly responsible for generation of different types of diseases and disorders. Hence protection of body against free radical is important and which can also be done by taking diet with maximum antioxidants. Naturally occurring antioxidant are very important in preventing body from various free radicals. Many medicinal plants and their extracts have been reported for potential anti-oxidant activity. Curcuma amada Roxb (Mango Ginger) is the most important genera come under the Zingiberaceae family. Chemically it has reported for the presence of wide range of phytoconstituents which include the flavonoids, terpenoids, tannins steroids, alkaloids, glycosides and essential oils. Due to presence of wide variety of phytoconstituents plant has very well traditional value reported for pharmacological significance for a variety of ailments. It effectively treats skin allergies, stomach problems, and high blood cholesterol and has been reported for antioxidant properties. In the present review work various research articles published on antioxidant activity of Mango Ginger Have been collected from various journal site and databases and explored systematically

Herbal medicines are mostly used from thousands of years in primary health care of society and community of both developed and developing countries. It mainly includes whole plant, herbs, extracts, isolated compounds, polyherbal preparations, phytoformulations etc. Identification of bioactive compounds from phytomedicines plays a very important role in drug development and drug design process. The characterization of phytomedicines is very much essential in the identification of compounds. For the purpose of identification two methods, Spectroscopy and Chromatography play important role. Fourier Transform Infrared Spectroscopy (FTIR) is the widely used technique which is mainly used to identify functional groups in herbal medicines. Various scientific research articles published on extraction, isolation, characterization and identification of phytoconstituents from medicinal plants and other forms of herbal medicines is being reviewed in this article. We have mainly focused on the FTIR characterization and identification of phytochemicals from herbal medicines and are briefly presented in this review work. Our present review article concludes that the FTIR spectroscopy plays very much essential role in the identification and characterization of bioactive compounds from herbal medicines.
