The quantity of L-Dopa extracted from in vitro plants regenerated from leaf and nodal explants of H. enneaspermus after 5 weeks of culture

Types	Leaf	Stem	Root
In vivo parent plants	6.78 ± 0.24c	4.33 ± 0.21c	2.11 ± 0.24b
In vitro plants regenerated from leaf explant	8.31 ± 0.27a	6.22 ± 0.27a	3.22 ± 0.22a
In vitro plants regenerated from node explant	7.43 ± 0.28b	5.02 ± 0.26b	2.86 ± 0.20b

Values represent the mean ± standard error of three experiments. Mean values followed by the same letters within a column are not significantly different according to Duncan’s multiple range test at 5 % level
