Abstract
Oenanthe linearis
Wall. ex DC., locally known as Jatira in Meghalaya, is a traditional wild leafy
vegetable valued for its health benefits and unique flavor. This study presents
a comprehensive evaluation of its amino acid profile using both ninhydrin-based
colorimetric and HPLC techniques. The total amino acid content was 91.16 µg/mg,
with 10.92 µg/mg present as free amino acids and 80.24 µg/mg as bound forms.
Notably, threonine (1033.76 µg/100 mg), aspartic acid (122.92 µg/100 mg), and
asparagine (119.88 µg/100 mg) were predominant, underscoring its high
nutritional potential. Essential amino acids including histidine, lysine,
valine, and threonine, alongside bioactive non-essential amino acids such as
glutamic acid and serine, contribute to the plant’s therapeutic promise. The
amino acid profile supports its roles in protein synthesis, immune modulation,
neurotransmission, and metabolic regulation. The predominance of bound amino
acids further suggests enhanced bioavailability upon digestion. These findings
highlight O. linearis as a valuable component in traditional diets and a
promising candidate for functional food development and nutritional security in
resource-limited regions.
