Nitrogen-to-protein conversion factors for some cereal products in Japan.
To evaluate a practical method of determining more accurately conversion factors for calculating the protein contents of foods from the total nitrogen content, 19 cereal products found in Japan wereExpand
Nitrogen-to-Protein Conversion Factors for Common Vegetables in Japan
Twenty (JAPANESE) vegetables in Japan were analyzed for total nitrogen, amino acid nitrogen, amide nitrogen, and nonprotein nitrogen and then calculated nitrogen-to-protein conversion factors wereExpand
Nitrogen‐to‐Protein Conversion Factors for Some Common Edible Mushrooms
Mushrooms (13) common to Japan were analyzed for total nitrogen (TN), amino acid nitrogen (AAN), amide-N and nonprotein nitrogen. The distribution of protein nitrogen averaged 67% to TN. AveragedExpand
Total purine and purine base content of common foodstuffs for facilitating nutritional therapy for gout and hyperuricemia.
Clinicians and patients could utilize that reference in nutritional therapy for gout and hyperuricemia through an HPLC method for purine analysis and determined purines in a total of 270 foodstuffs. Expand

A compound that inhibited angiotensin-I converting enzyme (ACE) activity was isolated from buckwheat powder and its chemical structure is 2''-hydroxynicotianamine, which is thought to be the hydroxy derivative of nicotianamines. Expand
Effects of angiotensin I-converting enzyme inhibitor from Ashitaba (Angelica keiskei) on blood pressure of spontaneously hypertensive rats.
The ACE inhibitor from Ashitaba contained in the anti-hypertensive fraction was speculated to be very similar to authentic nicotianamine based on a comparative study of inhibitory activity, mass spectrum analysis and thin-layer chromatographies. Expand

Distribution of a novel angiotensin I-converting enzyme inhibitory substance (2″-hydroxynicotianamine) in the flour, plant parts, and processed products of buckwheat
Abstract 2″-Hydroxynicotianamine (HNA) is a recently discovered angiotensin I-converting enzyme inhibitory compound present in buckwheat which displays hypotensive activity. Here, HNA levels inExpand
Changes in Free Amino Acids of Tempe during Preparation with Velvet Beans(Mucuna pruriens).
ベルベットビーンを原料とするテンペを製造し,各製造工程における遊離アミノ酸の変化,およびベルベットビーン中の主要な非タンパク性遊離アミノ酸であるDOPA量の変化にっいて検討し,以下のような結果を得た.1) アミノ酸分析計で遊離アミノ酸の分析を行った際,含硫アミノ酸であるメチオニンと同じ溶出時間に多量に検出されたアミノ酸はDOPAであることを確認した.2)Expand
