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.

    STUDIES ON SEASONAL VARIATION OF BIOACTIVE COMPOUNDS IN Salvia spp.
    (UHF Nauni, 2023-11-28) ABHISHEK KUMRA; Dr. Reena Sharma
    The present investigation entitled “Studies on seasonal variation of bioactive compounds in Salvia spp.” was carried out in the field and laboratory of the Department of Forest Products, College of Forestry, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2022-23. The study was conducted under two objectives namely (i) To standardize the method of extraction for rosmarinic acid (ii) To study the seasonal variation in rosmarinic acid and other bioactive compounds with growth and development of Salvia rosmarinus Spenn. and Salvia sclarea L. For standardization of extraction methods in Salvia rosmarinus and Salvia sclarea three different extraction methods viz. soxhlet extraction, reflux extraction and sonication assisted extraction were used with four different solvents. In S. rosmarinus maximum rosmarinic acid (2.23%) content was obtained in soxhlet extraction for six hours duration with methanol-water (70:30) and highest total extract (%) (40.66%) was recorded in soxhlet extraction for eight hours duration with methanol-water (70:30). In S. sclarea maximum rosmarinic acid content (1.55%) was obtained in soxhlet extraction for six hours duration with methanol-water (70:30) and highest total extract (%) (36.04%) was recorded in soxhlet extraction for ten hours duration with methanol-water (70:30). Monthly variation in rosmarinic acid was studied in four germplasms of rosemary viz. SS1, SS2, SS3 and SS4. On the basis of seasonal variation, maximum rosmarinic acid content (SS1-1.33%, SS2-2.42%, SS3-2.51% and SS4-2.23) in S. rosmarinus was recorded in the month of November and minimum rosmarinic acid content (SS1-0.21%, SS2-1.34%, SS3-1.37% and SS4-0.41%) was recorded in the month of July in all four germplasms. In S. sclarea maximum rosmarinic acid content (1.55%) was observed in the month of April (vegetative stage) and minimum (0.004%) was recorded in the month of July (seed setting stage). Total phenolic, flavonoid content and anti-oxidant activity in S. rosmarinus was highest in November and lowest in July in all four germplasms. In S. sclarea, total phenolic, flavonoid content and anti-oxidant activity was maximum in April and minimum in month of July. Simple and easy HPLC method was developed for quantification of rosmarinic acid in S. rosmarinus and S. sclarea.
