Abstract

A research work was conducted to find out the chemical composition of Asparagus densiflorus sprengeri under the influence of different agro-climatic conditions of Punjab province, Pakistan. Experiment conducted with Complete Randomized Design (CRD). Triplicate samples of shoots and roots collected from various localities were analyzed for each treatment. Fresh plants of A. densiflorus sprengeri were collected from seven different sites of Punjab. Time of sampling is from March to April. After air drying, samples were analyzed for their Malondialdehyde (MDA), Ascorbic Acid (AsA) and Total Phenolic (TPhe). MDA, AsA and TPhe concentrations differed significantly (p<0.05) from locality to locality. As the contents of MDA concerned the maximum concentrations were recorded from the shoot (4.54 ± 0.027 mg g-1) and root (3.03 ± 0.307 mg g-1) of plants selected from University of Agriculture, Faisalabad (UAF) and TT Singh respectively while the lowest from shoot (1.13 ± 0.165 mg g-1) and root (0.94 ± 0.120 mg g-1) collected from Multan and UAF respectively. The highest AsA concentrations of shoot (0.436 ± 0.0023 mg g-1) and root (0.424 ± 0.0035 mg g-1) were recorded from UAF and Govt. College University, Faisalabad (GCUF) respectively whereas minimum of AsA of shoot (0.206 ± 0.0008 mg g-1) and root (0.224 ± 0.0093 mg g-1) from TT Singh. The highest TPhe were present in the shoot (0.451 ± 0.019 mg g-1) and root (0.529 ± 0.019 mg g-1) of plants collected from UAF and Nursery (Faisalabad) respectively while minimum of shoot (0.165 ± 0.0065 mg g-1) and root (0.265 ± 0.012 mg g-1) from Multan and TT Singh respectively. On the basis of results obtained it can be concluded that environmental conditions significantly (p<0.05) influenced the chemical composition of A. densiflorus.
