Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    MORPHO-CHEMICAL STUDIES OF MARKET SAMPLES OF DRUG KUTKI (Picrorhiza kurroaRoyle exBenth.)
    (UHF,NAUNI, 2015) THANI, PARBAT RAJ; SHARMA, YASH PAL
    ABSTRACT The present investigation entitled “Morpho-chemical studies of market samples of drug Kutki (Picrorhiza kurroaRoyle exBenth.)” was carried out in the department of forest products, Dr. Y. S. Parmar university of Horticulture and Forestry, Nauni, Solan (India) during 2012-2014. Market samples of drug “Kutki” were procured from different markets of India. The samples were evaluated for organoleptic and histological characteristic, chemical profile through TLC and HPLC analysis. Out of 35 samples, 34 samples were genuine having all the characteristics resembling to drug “Kutki” (Picrorhiza kurroa) and one sample was spurious. TLC profile of genuine samples showed characteristic spots of picroside-I and picroside-II at Rf 0.56 and R f 0.44 respectively. The picriside-I and picroside-II content in genuine samples ranged from 0.399 per cent to 7.383 per cent and 0.517 per cent to 7.666 per cent respectively. Picroside-I and picroside-II were absent in spurious sample. Four different extraction methods viz. soxhlet, extraction by refluxing, microwave assisted extraction and sonication assisted extraction were tested for extraction of picroside-I and picroside-II from the rhizome of Picrorhiza kurroa. Sonication assisted extraction for 36 minutes with methanol as solvent yielded 44.269 per cent extract with 6.825 per centpicroside-I and 5.291 per cent picroside-II content, which was better in comparison to other methods in terms of time consumption and yield. Impact of storage condition and duration on picroside-I and picroside-II content in “Kutki” was also studied. The study showed that the content of picroside-I and picroside-II decreased with the increase in storage duration irrespective of storage condition. However the loss in picroside-I and picroside-II with storage was maximum when “Kutki” samples were stored under humid condition (85 % humidity, 25 o C) and minimum loss was observed when samples were stored at low temperature (4 o C-6 o C).
