(1994) reported the HPLC analysis of various lichen
secondary metabolite with photodiode array detector.
* Scientists have identified 2 plants--Euterpe oleracea and Centella asiatica--that produce
secondary metabolites to help them survive some of the harshest environmental conditions.
Conclusion:
Secondary metabolites of both fungi contained some biologically active compounds.
Plants synthesize a diversity of low molecular weight, structurally complex chemical compounds, commonly known as
secondary metabolites (Moore, Andrew, Kulheim, & Foley, 2014) These are present mainly under stress conditions, but their absence does not cause harmful effects to the plants (Edreva, 2005; Edreva et al., 2008; Khan, Aliabbas, Kumar, & Rajkumar, 2009).
Many factors including stresses like drought, nutrient deficiency and diseases ultimately down regulate the accumulation of
secondary metabolites in plants.
No antioxidant activity was found in the hydroalcoholic extracts (HE) measured by FRAP, HRSA, and LPIA under equal concentrations with polarity fractions (Figure 1), while
secondary metabolite contents, including TPC, TAC, and TSC, significantly varied between the five fractions.

secondary metabolites.
Inoculum age plays a vital role in induction and production of
secondary metabolites as the
secondary metabolites are induced in the late stationary phase of the bacterial growth.
Among
secondary metabolites determined, the common
secondary metabolites present in leaf and internode tissue were Toluene, a-sphinosterol, Tetradecane, Pentadecane, Hexadecane, Octadecane, Hentriactone, and 9,12-Octadecadienoicacid[7,7].
