Received: 21-06-2018; Revised: 29-06-2018; Accepted: 19-07-2018 Abstract: The postharvest experiment was conducted to maximize the shelf life of Jasminum grandiflorum without losing its fragrance using with different chemical solution in department of Crop Physiology, Tamilnadu Agricultural University during 2017 - 2018. The demand for this species for oil extraction is more compared to other species. Among the Jasmine flower production major quantity of Jasmine flowers are utilized for isolating and manufacturing Jasmine oils. The experimental design followed for this study is FCRD. The chemical solutions viz., silver nano particle (20 ppm), Boric acid (4%), sucrose (4%), NAA (100 ppm), BA (500 ppm), α-AIB (20µM) are used as anti-senescence. After chemical treatment the flower buds packed in polypropylene bags (200 gauges) and stored in ambient and cold storage condition. The observation was made periodically up to flower senescence. Among the different chemical treatment silver nano-particle (20 ppm) having the significant effect on fragrance and shelf life over control. Keywords: Jasminum grandiflorum, Fragrance. Shelf life, Storage, Post-harvest treatment Introduction Jasmine is an important fragrant flowers used from very ancient period. Buds and opened flowers are used for making garlands and bouquets for various purpose. In Tamilnadu and UP these flowers are used for production of perfumed hair oils. Large quantity utilized for isolating and manufacturing jasmine oils in Europe and Mediterranean Countries. Its unique odor can’t be imitated by a mixture of any known synthetic aromatic chemicals and natural isolates. The discovery of the invention structure of jasmine ketone as now brought the estimation of the common smell by blend a stage close up. On the off chance that the present high flavor consistent, aromas will be contended to way out an ever increasing number of manufactured substitutes and in result, a dropping off in the importance for the normal item may happen.

It is essential that Government of India ought to consider the fare arranged Jasmine Industry as a thrust region for development and support. Jasmine constitutes a gathering of fragrant blossoms which are monetarily developed all through the nation over a region of around 8000 hectares. Jasmines contribute significantly to the national economy, and every year about Rs. 20 crores worth of blooms is deliver in India. Tamil Nadu is the leading state in the India for production and export of Jasmine flower bud. Fresh flower buds are delivered for inside exchange and furthermore for fare to the neighboring nations like Srilanka, Singapore, Malaysia and to the Gulf nations. The family Jasminum is accounted for to include around 200 species. A basic investigation of this species uncovered the quantity of genuine species to be just 89 of which 40 occupy in the Indian sub- landmass. In South India, huge amounts of Jasmine blossoms are utilized by ladies society for adorn their hair. The blossoms are additionally utilized for the manufacture of scents and attars. The world renowned Jasmine Oil is extricated from the blooms of Spanish Jasmine (Jasminum grandiflorum). The Jasmine oil is viewed as one of a kind as it mixes well with botanical concentrates and it is exceedingly esteemed all through the world for creating high review scents. The oil finds the place in cleanser and restorative businesses too. In countries like Japan, the U.K., USA, USSR, Scandinavia, East Europe etc., there is a growing demand for spirituous perfumes and colognes during recent past years. In India it still produces attars and non-spirituous perfumes by traditional method so it lost its leading position as a perfume producer because of it. It is thus apparent that there is a good scope for large scale development of spirituous perfume based on Jasmine for export purpose. Based on the above constraints the present
