Solanum trilobatum Linn (Solanaceae) is a thorny shrub widely distributed in Bengal, Uttar Pradesh, Southern India and Srilanka in moist places. This plant is well known in Ayurveda and Siddha system as ‘Alarka and Tuduvelai’, respectively. Leaves, roots, berries and flowers are used for cough. The constituents such as solasodine and β-solamarine have been isolated from whole plant. Plant growth regulators are substance that influences physiological processes of plants at very low concentration. Abscisic acid (ABA) is a many important plant growth development processed. Paclobutrazol (PBZ) is a triazolic group of fungicide which has plant growth regulating properties. Salicylic acid (SA) is phenolic phytohormones and is formed in plants with role of plant growth and development. The given treatments were started at 70th day followed by 80th 90 and 100th days. The groups were treated with respective growth hormones by spraying method to ABA 10µg/L, PBZ 10mg/L and SA 500µg/L. After 10th day, the plants were harvested and analysed on over all analytical values assessment plant treated with PBZ followed by ABA, SA, Control plants. Qualitative on secondary metabolites on alkaloids, terpenoids, flavonoids, saponin, tannins and phenol content in present, but gum & mucilage, fixed oils & fats, phytosterol absences. Quantitative of secondary metabolites on over all metabolites values assessment plant treated with ABA followed by PBZ, SA and Control plants
