Prunus salicina Lindl. - syn.Prunus triflora Roxb. - Rosaceae
李 li (chin.), Japanese plum, Chinese plum, Japanische Pflaume, Chinesische Pflaume

„Prunus salicina should not be confused with the Prunus mume, a related species of plum also grown in China, Japan, and Korea. Another tree, the Korean cherry - (Prunus japonica), is also a separate species despite having a Latin name similar to Prunus salicina's common name.“

„The most important compounds of P.salicina [aroma, with higher odor units] are β-ionone (despite its low concentration, this compound has a very low odor threshold) and nonanal, as well as hexyl acetate in ‘Blackamber’.“ Fruits of the ‘Blackamber’ clonal accessions showed higher concentrations of the volatile compounds than ‘Friar’, also for hexanol, hexanal, phenylacetaldehyde, hexyl acetate and y-dodecalactone.

„The aroma volatile compounds of three commercial Japanese plum cultivars (Pioneer, Laetitia and Angeleno) were determined for a seven week period to include samples from three different maturity stages (immature, harvest and tree-ripe) over two fruiting seasons. HS-SPME was used for extraction coupled with GC-TOFMS for separation and identification. A total of 35 different compounds was identified with 10 of the compounds found to be generic amongst the three cultivars, viz. hexanal, 2-hexenal, hotrienol, linalool, trans-linalool oxide, cis-linalool oxide, p-menth-1-en-9-al, β-damascenone, 2-bornene and α-terpineol. Each cultivar had five unique compounds resulting in different aroma profiles for each of the maturity stages and distinct separation patterns using discriminant analysis. The compounds contributing most to the distinctness of the maturity stages within a cultivar were identified and found to be different from the compounds identified as important for separating the cultivars.“
