“…Liquid chromatography–mass spectrometry (LC–MS) results showed that the main components of Shensu IV were l-Carnitine, P-lysoPC (LPC) 16:0, Coumaroyl tyramine, Tetramethylpyrazine, LPC 18:1, Choline, (S,S)-Butane-2,3-diol, and Scopoletin. We further found that nephrotic rats displayed pathological alterations in kidney tissues and ultrastructural changes in glomerular podocytes; however, these effects were reversed with Shensu IV treatment. …”

“…Focusing on the aromatic black rice, the samples appeared to contain high level of both compound groups of aldehydes (3-methylbutanal, 2-methylbutanal, 2-methylpropanal, pentanal, hexanal) and alcohols (butane-2,3-diol, pentan-1-ol, hexan-1-ol). Biosynthetically, these distinctive black-rice volatile compounds were proposed to be formed from the metabolic degradation of branched-chain amino acids (L-leucine, L-isoleucine and L-valine) and polyunsaturated fatty acids (linoleic acid and α-linolenic acid), involving the branched-chain aminotransferases and keto-acid decarboxylases and the 9-lipoxygonases and 13-lipoxygeases, respectively. …”
