The book provides a comprehensive examination of Grewia asiatica and Ricinus communis, detailing their collection, extraction, and pharmacognostical evaluation. It includes a thorough literature survey and outlines the scope of research. Key sections cover qualitative phytochemical analysis, TLC, and HPTLC methods, alongside biological investigations assessing in vitro and in vivo antioxidant activities using various estimation techniques. This structured approach highlights the medicinal potential and biochemical properties of these plants.

The research focuses on developing Aqueous Polymeric Dispersions (APD) using four Eudragit polymers through emulsification solvent evaporation. The process involves creating the dispersions, optimizing polymeric films, and characterizing the freeze-dried dispersions. A key goal is to replace organic solvents with aqueous alternatives, offering advantages such as cost reduction, non-toxicity, ecological benefits, enhanced manufacturing safety, and improved availability for pharmaceutical applications.

Exploring the role of free radicals in human diseases, this book delves into the various types of free radicals and their impact on health. It highlights the importance of antioxidants in combating oxidative stress, featuring a comprehensive list of plants known for their antioxidant properties, such as Amla, Garlic, and Turmeric. Additionally, the text covers in-vitro methods for assessing antioxidant activity, providing a scientific approach to understanding these compounds. References are included for further research on the topic.

The study focuses on evaluating the memory-enhancing potential of Plumbago zeylanica and Acorus calamus. Plumbago zeylanica, known for its use in Ayurvedic medicine as a rejuvenator, contains the alkaloid Plumbagin, which may serve as a nervine tonic. The research employed UV spectroscopic methods to analyze the phenolic, flavonoid, tannin, and alkaloid contents of both plants. Notably, Acorus calamus exhibited a higher flavonoid content at 88%, compared to 50% in Plumbago zeylanica, with specific measurements expressed in Quercetin equivalents.
