Abstract:

Objective: This study aims to investigate the volatile compounds and flavonoid composition in leaves of Dalbergia odorifera, D. cochinchinensis and D. sissoo, and their differences, so as to provide scientific evidence for the development and comprehensive utilization of non-wood forest products derived from Dalbergia species. Method: The solid-phase microextraction method was used to extract the samples, and the GC-MS was used to detect volatile compounds. The relative odor activity values (ROAVs) were calculated and the key odor substances were determined through the odor threshold and the relative content. All identified compounds were queried in Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and the key bioactive components were screened based on Oral Bioavailability ≥ 20% and Drug-Likeness ≥ 0.10. Meanwhile, relevant targets and associated diseases were further analyzed. Flavonoids were extracted by ultrasonic wave, and LC-MS/MS was applied to detect the flavonoid composition. Result: A total of 80 volatile compounds were identified from D. odorifera leaves, majorly including methyl salicylate (14.52%), benzyl alcohol (11.64%), β-bisabolene (6.08%) and phenylethyl alcohol (5.52%). A total of 31 volatile compounds were detected in D. cochinchinensis leaves, including α-ionone (17.12%), 1-(1-methyl-2-cyclopentenyl) ethenone (16.45%), 3,5-octadien-2-one (16.34%), β-ionone (14.89%), 3,4-dimethylcyclohexanol (7.18%), and dihydroactindiolide (6.35%). A total of 71 volatile compounds were identified from D. sissoo leaves, including β-ionone (10.26%), d-limonene (9.25%), 2-pentylbenzoate (6.50%), and benzyl alcohol (5.35%). A total of 16 flavor compounds were identified from D. odorifera leaves, with the key flavor compounds being α-ionone, methyl salicylate, nonanal, and geranylaceton. Six flavor compounds were identified in D. cochinchinensis leaves, with the key flavor compounds being α-ionone and geranylaceton. Twelve flavor compounds were identified in D. sissoo leaves, with the key flavor compounds being nonanal, geranylaceton, d-limonene, and naphthalene. Four medicinally active compounds were identified in D. odorifera leaves, including (+)-cyclosativene, α-copaene, β-copaene and caryophyllene oxide, while only one active component of farnesyl acetone was identified in D. cochinchinensis leaves, the medicinally active compounds identified from D. sissoo leaves contained (+)-cyclosativene, α-copaene, caryophyllene oxide and dibutyl phthalate. There were 14 types of flavonoids in D. odorifera leaves, majorly including tectorigenin (62.01%), diosmetin (13.68%) and prunetin (6.51%). There were 22 flavonoid species in leaves of D. cochinchinensis, majorly including rutin (30.01%), typhaneoside (24.19%) and kaempferol 3-neohesperidoside (9.58%). However, in D. sissoo leaves, there were 11 flavonoid species, majorly including prunetin (60.80%), rutin (18.02%), and nicotiflorin (7.80%). Conclusion: The leaves of the above three Dalbergia species are rich in volatile compounds, including a variety of flavor and medicinally active components, as well as flavonoids. The findings show their great development potential for applications in pharmaceuticals, fragrances, and personal care products.
