| Abstract: | The fruits of Artocarpus gomezianus Wall. ex Trecul. var. lakoocha Roxb. were collected from different altitudes of Central Western Ghats which differ in their topography, vegetation, social, cultural and food habits of the local people. The screenings of secondary metabolites revealed presence of alkaloids, phenols, flavonoids, tannins, steroids and saponins in the fruit samples of all the regions. The quantitative determination of secondary metabolites shown that the alkaloids were dominant at all the sampling stations followed by lignin, phenols, flavonoids, tannins and steroids. However, the amount of steroids and tannins were same at all the sampling stations except at higher altitudes where tannins are least. There was a shifting among the flavonoids and phenols in the middle lower and middle higher altitudes. Though alkaloids were dominant secondary metabolites and steroids were the lowest, with respect to concentrations of individual alkaloids, remarkable variations were observed. Among the six secondary metabolites, the concentration of steroids, tannins and phenols were high at the lower and higher altitudes and low in middle altitudes. In contrast to phenols, tannins and steroids, the concentration of flavonoids was more in the middle and lower in higher altitudes and lowest in higher and lower altitudes. The concentration of alkaloids and lignin did not show any relationship with variation in altitudes. The quantitative values of secondary metabolites are subjected for correction studies with reference to different altitudes, average rainfall and temperature. The +ve and –ve correction at 0.01 and 0.05 level is emphasized. The simple correlation coefficient between weather data and secondary metabolites revealed significant information. The percentage of secondary metabolites showed P ≤ 0.01 level significance with altitudes at all the stations except a few sites. The qualitative separation of secondary metabolites by thin layer chromatography method revealed that alkaloids, flavonoids and glycosides have three distinct spots with different hRf values. Steroids revealed two spots and saponins revealed one spots along with different hRf values. |
