Gastrodia elata Blume, an achlorophyllous orchidplant, has been used in traditional medicine and harvests inspring and fall. Here we investigated the quantitative changesof amino acids in G. elata by harvest times and seed tubers.
In the results, we found that there was not big difference incontents of total amino acids but the distribution of aminoacids differed depending on harvest times. 19% of total aminoacids were asparagin and valine, an essential amino acid,occupied 10% within total amino acids in the tubers harvestedin October. Among amino acids in the tubers harvested inApril, serine occupied 23% and arginine, an essential aminoacid, occupied 10% within total amino acids in tuber. Interestingly,the use of sexually propagated seed tubers produced highconcentration of total amino acids compared to vegetativelypropagated seed tubers. As for sexually propagated seedtubers, essential amino acids contents similar to the tubesharvested in October and nonessential amino acids contentssimilar to the tubers harvested in April. In this study, wefound that amino acids contents in G. elata tubers altereddepending on various cultivation practices. Therefore if theseresults can be applied to food industry, the value of G. elataas a natural food resource will be enhanced to a great extent.
