Rauvolfia species, commonly known as Sarpagandha, has been traditionally used in Ayurveda for curing high blood pressure, hypertension, snake bites, fever, and mental illnesses. Due to its wide variety and differences in chemical composition, it is necessary to develop an efficient and reliable method for rapid screening and determination of phytochemicals in the extracts of the Rauvolfia species. This book will provide qualitative and quantitative comparative phytochemical investigations of selected medicinal plants from the Rauvolfia genus using liquid chromatography-mass spectrometry (LC-MS) techniques. The results will help in assuring the efficacy and safety of Rauvolfia herbal products.Features: Collection of Ayurvedic features and scientific evidence of important medicinal plants. Discusses chemical signatures for the identification of Rauvolfia (Sarpagandha) and its products. Easy-to-use analytical procedure for quality control of Rauvolfia and its products.

Piper betle (betel vine) a pan-Asiatic, tropical plant, which can also grow under mild subtropical areas, is essentially grown for leaves which are chewed with array of additives besides slaked lime. The plant is cultivated widely in India and its surrounding areas. Phytochemistry of Piper betel landraces presents a brief on the distribution, historical and cultural aspects, and properties ascribed to this plant in the ancient texts. Phytochemical and pharmacological information has also been included to underscore the importance of this plant in the present time. A detailed account on metabolic profiling employing modern methods is included, such as real-time, direct analysis of the flight mass spectrometric method and chemometric analysis for characterization of the available biodiversity and signatures specific to gender and geographical location. It was also possible to identify the gender of unknown landraces, with the help of principal component analysis.Features: Elaborates on the chemical diversity within Piper betle. Piper betle leaves have mouth freshening antimicrobial compounds. Use of chemical signatures for the identification of different Piper betle landraces, their gender and geographical locations.

Withania is a genus of the nightshade family of flowering plants distributed in the subtropical regions from the Mediterranean to South East Asia. Only two species, W. somnifera and W. coagulans, are found in India. The most common species is W. somnifera (WS), which occurs naturally in the subtropical regions from the Mediterranean through Africa to the Middle East, the Indian Continent, Sri Lanka, South East Asia, subtropical America and Australia. It is a perennial shrub that grows to 75 cm (.75 m) tall with tomentose branches, oval yellowish green leaves, orange red berries and a papery calyx, and it survives harsher climatic conditions. In Ayurveda it is believed the plants which survive harsh conditions have strong healing and tonification properties. The main bioactive phytoconstituents of WS are withanolides (steroidal lactones), alkaloids, flavonoids, sterols, phenolics and others. Among the various withanolides, withanolide A, withaferin A, withanone and withanolide D are the most abundant, having various activities. WS is a wonder herb with a broad spectrum of pharmacological properties, such as antioxidant, antidepressant, aphrodisiac, antiulcerogenic, antivenom, anti-inflammatory, antiarthritic, anticancer, antiparasitic, antimicrobial, anticancerous, antidiabetic, antitumor, hemopoetic neuroregenerative, immunomodulatory, cardioprotective, radio-sensitizing, rejuvenating, antistress, sedative, hypoglycemic, thyroprotective, adaptogenic, antispasmodic, immunomodulatory, immunostimulant and antiaging properties.The simultaneous quantitative analysis of six major bioactive withanolides in five varieties of WS and in different plant parts (root, stem and leaf) of WS was accomplished. This method is also applicable to control the quality of commercially formulated products which contain WS bioactive compounds. Results indicated the WS variety NMITLI-135 showed the maximum abundance of withanolides at pH 8.5, EC-0.5 dS m−1, ESP-13 in sodic soil. Our results showed this readily available, rapid and reliable method is suitable for the routine analysis and effective quality control of raw materials and finished products.FEATURES Presents a collection of Ayurvedic features and scientific analytical and pharmacological evidence of important medicinal plants of Withania somnifera Useful for natural product researchers, faculty, students and herbal product manufacturers Uses advanced hyphenated techniques for assessing phytoconstituents
