Amino acids in sandal (Santalum album L) with special reference to cis-4-hydroxy-l-proline and sym. homospermidine.

Kuttan R, Panikkar B, Binitha PP - Springerplus (2015)

Bottom Line: Sandal also contains sym. homospermidine which is not present in any other plants till today.Moreover sandal leaves contain γ-glutamyl derivative of the lachrymatory precursor of onion, γ-glutamyl-S-propenyl cysteine superoxide.This review summarizes the studies on the amino acids in sandal.

ABSTRACT
Sandal (Santalum album L) contains several interesting amino acids and amines which are not seen in other plants. This includes cis-4-hydroxy-l-proline in free form in leaves, flowers and seeds while trans-4-hydroxy-l-proline in bound form. Traces of 3, 4 dehydroproline is also detected in sandal leaves. Biosynthesis of cis-4-hydroxy proline indicates that hydroxylation taken place at proline present in peptidyl form especially bound to glutamic acid and aspartic acid. Pyrrolizidine-2-carboxylic acid an interesting isatin positive heterocyclic compound is also present in sandal leaves. Sandal also contains sym. homospermidine which is not present in any other plants till today. Biosynthesis of sym. homospermidine goes by a unique pathway of putrescine oxidation, Schiff base formation, condensation and reduction. Moreover sandal leaves contain γ-glutamyl derivative of the lachrymatory precursor of onion, γ-glutamyl-S-propenyl cysteine superoxide. This review summarizes the studies on the amino acids in sandal.

Fig2: Demonstration of presence of 3, 4 dehydroproline in sandal leaf extract using paper chromatographic procedure

Mentions: Our initial studies indicated that 3, 4 dehydroproline may be present in sandal leaves at very low concentrations. It was found that during the column separation 3, 4 dehydroproline which reacts with Ehrlich’s reagent was eluted much later than the hydroxyl proline. Fractions containing hydroxyproline and 3, 4 dehydroproline were pooled and concentrated and unidimensional chromatography using butanol-acetic acid–water (4:1:1) separated it from hydroxyl proline as a defined peak with an Rf value very similar to that of 3, 4 dehydroproline (Fig. 2).Fig. 2
