Bioactive compounds like carotenoids, phytosterols, flavonoids and phenolic acids have been identified in number of fruits and vegetables. But due to their less bioavailability owing to insolubility, their application in food industry is still unsuccessful. In this review, bioactive compounds present in bananas and peanuts and their potential health benefits are discussed. Peanuts possess many important compounds like resveratrol, phenolic acids, flavonoids and phytosterols which inhibit the absorption of cholesterol from diet. Moreover, it is also good source of Co-enzyme Q10 and contains all the 20 amino acids with highest content of arginine. Banana also contains various essential bioactive compounds such as phenolics, carotenoids, biogenic amines and phytosterols. Most of the compounds have been reported as potent antioxidants and are compelling in securing the body against different oxidative stress related conditions.

The research trail was conducted in the field of Horticulture PMAS Arid Agriculture University Rawalpindi during2015-16 using 3 replicated RCBD. Two varities of Lettuce grand rapid and icebergwere tested. Physical Attribute data i.e. Number of leaves, Plant height, Total leaf Area per Plant, Fresh plant Weight, Leaf dry weight and organoleptic properties were observed. The average number of leaves mean between the two varieties was observed to be highly significant. Iceberg lettuce produced maximum number of leaves with average mean 8.98. Grand rapid lettuce produced highest leaf length with average mean 14.82 cm compared with iceberg lettuce which produced leaf length with average mean 12.34 cm. In case of iceberg lettuce, maximum area was depicted in plants grown in T1 that was 93.07 cm 2. Iceberg lettuce produced heavier leaf with 501.3 g compared with grand rapid lettuce (308.6g). Leaf dry weight of iceberg lettuce (16.4 g) showed significant difference with grand rapid lettuce with 9.8 g. In grand rapid lettuce highest dry matter is recorded in T1 with dry weight of 14 g. The highest significant values for aroma were 4.5 and 3.5, found in lettuce grown in T1 and T2, respectively. But least values were 2.6 and 2.1 in T2 (V2) and T3 (V1) respectively .All the physical attributes were highly significant among treatments and varities. From this study it was observed that hybrid varity iceberg is better than grand rapid morphologically. Where as in treatments, T1 (chicken manure) was good with regards to physical attribute.

Phytochemical properties of two varieties of Lettuce grand rapid and ice-berg were studied in this experiment. The Complete Randomized Design was followed in the laboratory of Horticulture Department, PMAS Arid Agriculture University Rawalpindi. Highest activity of the superoxide dismutase (SOD) enzyme (159.64 U g-1 protein) was observed in V2. Minimum activity of SOD enzyme (141.14 U g-1 protein) was calculated in V1, lettuce grown in T0 (Control) treatment. Highest activity of the Poly Phenol Oxidase enzyme (32.59 U g-1 protein) was observed in V2 grown in T0 Treatment (Control), Minimum activity of PPO enzyme (28.14 U g-1 protein) was calculated in V1 lettuce grown in T3 (Peat moss+ chicken+ compost) treatment. Highest activity of the Peroxidase enzyme (28.43 U g-1 protein) was observed in V2 grown in T3 Treatment (Peat moss+ chicken+ compost). Minimum activity of POD enzyme (27.08 U g-1 protein) was calculated in V1 lettuce grown in T0 (Control) treatment. Highest activity of the CAT enzyme (24.17 U g-1 protein) was observed in V2 grown in T3 Treatment (Peat moss+ chicken+ compost. Minimum activity of CAT enzyme (20.13 U g-1 protein) was calculated in V1 lettuce grown in T0 (Control) treatment. All analytical attributes were highly significant among treatments as well as between two varities of lettuce. From this study it was concluded that hybrid variety ice-berg is better than grand rapid phytochemically. In case of treatments, T3 (Peat moss+ chicken+ compost) give best results.
