Aloin was selectively determined
59 in different matrices by HPTLC densitometry in fluorescence
60 mode (Coran et al., 2011). Earlier, barbaloin was estimated in
61 A. vera and in its commercial products (Pandey et al., 2012). An
62 efficient micropropagation protocol was adopted in A. vera in
63 Murashige and Skoog (MS) medium supplemented with growth
64 regulators (Aggarwal and Barna, 2004).
