Grape (Vitis vinifera) member of family vitaceae, is an excellent source of phenolics, particulary in the skin and seeds. Phenolic compounds have attracted much interest recently, because they are potent antioxidant and exhibit various other physiological activities including anticarcinogenic, antimicrobial, anti-inflammatory and antihypertensive activities associated with reduced risk of chronic diseases like cardiovascular diseases. The method of processing and extraction play a vital role in the quality of nutraceuticals extracted. The traditional extraction techniques are time-consuming and require relatively large quantities of solvents. In view of increased awareness for health related compounds from plant materials, there is an increasing demand for better extraction techniques which are nontoxic, environmentally safe and inexpensive. This review paper discusses briefly on grape phenolics, important nutraceuticals extracted from grape seeds and its positive health effects. The possibility of application of novel extraction methods like sonication assisted extraction, microwave assisted extraction techniques and supercritical fluid extractions for efficient extraction of plant are discussed.

Chillies, the dried red fruit of genus capsicum represent the essential fraction of agricultural produce. Chilli, imparts colour and characteristic pungent flavour apart from being used as a seasoning factor. Analyzing the physicochemical characteristics of chilli is important to understand their quality. Considering this moisture, ash, water insoluble ash, acid insoluble ash, capsaicin content, colour value, total carbohydrate, protein, fat, fiber, total phenols were analyzed using the standard procedures for the chilli samples viz., Sattur S4, Sangli Sannam, Tomato Chilli and Byadagi. Colour value test (Hunter Lab Colour Meter) confirms that all the samples had bright red with relative yellow colour recommended by BIS (IS 2322:1998). Basic knowledge about existing varieties and its quality factor is ultimately necessary to exploit their hidden positive bioactive markers at appropriate places.
