In addition to known cucurbitacins, a glucosphingosine type cerebroside and amino acids were isolated from the roots of Trichosanthes kirilowii. The structure of cerebroside was determined as soya-cerebroside I by means of spectroscopic methods. Fifteen amino acids were identified as aspartic acid, glutamic acid, serine, glycine, histidine, citrulline, threonine, alanine, proline, tyrosine, valine, isoleucine, leucine, phenylalanine and tryptophan, among which the major components such as citrulline, phenylalanine, leucine/isoleucine and valine were isolated.

From the EtOAc fraction of the MeOH extract of Albizzia julibrissin (Leguminosae）, a rare 5-deoxyflavone (geraldone, 1）, isookanin (2）, luteolin (3）, an isoflavone (daidzein, 4）, five prenylated flavonoids ［soph6f1avescenol (5）, kurarinone (6）, kurarinol (7）, kuraridin (8） and kuraridinol (9）］, a cerebroside (soya-cerebroside I, 10）, and $(-)-syringaresinol-4-O-{\beta}-D-glucopyranoside$ (11） were isolated and characterized on the basis of spectral data. Compounds 2, 3, and 11, showed 1, 1-diphenyl-2-picrylhydrazyl radical scavenging activity.
