Identification of two new sugars in wastages of Crocus sativus L. using GC-MS

During the past few decades in the world, using plants with various applications such as pharmaceutical and industrial are growing. Herbal medicines are used to treat a variety of diseases in which the saffron (Crocus sativus L.) is one of the most important herbal medicines.Saffron is one of the native and valuable plants of Iran that has a significant role in the economic and social conditions of southern and central Khorasan province.Stigmas are the only part of saffron that are used and other parts are discarded as wastage. In this study, we investigated the phytochemical study of wastage of saffron. The wastage of saffron was collected from a farm near Birjand (32°24'06.7"N 59°16'53.5"E) in November and then were transferred to the freezer set at -15 ° C. In this study, the extract of petal and stamen was obtained from saffron waste using methods of maceration and ultrasonic with water, ethanol and methanol as solvent, and at the end ofthis study, the presence of carbohydrates were proved with several methods and the type of carbohydrates in saffron's wastage was determined using GC- MS methods. The presence of D- Allose and Levoglucosan were provided with GC-MS analyses for the first time.
