2026-07-23 Alkaloids and phenolic constituents from Buteae Monospermae semen-raw data doi:10.57760/sciencedb.nprd.00329 en In order to study the chemical composition of purple rivet, the ethyl acetate part of purple rivet was separated and purified by silica gel, ODS, MC Ⅰ, Sephadex LH_20 gel and semi preparative HPLC, and its structure was identified by modern spectral techniques such as 1 H NMR, 13 NMR and MS. Finally, 20 compounds were obtained, including 3R_ [(3, s_format_ β _ lactam), ethyl acetate] _ hydroxyindole (1), oleurol (2), 2 (3,4,5-dihydroxyphenyl) _1,3-dioxaldehyde-5-aldehyde (3), lanceolatin B (4), dihydroquercetin (5), and o Ⅴ alifolin(6) 、2_(2_methoxyphenyl)furo[2 ,3_h]chromen_ 4_one(7) 、pongapin(8) 、desmethoxy kanugin (9) 、2_(1 ,3_benzodioxol_5_yl)_3 ,6_dimethoxy_4H_1_benzopyran_4_one (10) 、 (2s)_3 ,4 , _methylenedioxy_6 Nie, 6 Nie, dimethylchromeno_ [2 Nie, 3 Nie: 7,8] _fla V anone (11), 6, 6, d_dimethylpyrano [2, 3,: 7,8] fla_ V one(12) 、3_hydroxyisolanchoearpin(13) 、_(4_hydroxyphenyl)_3_methoxy_4H_chromen_4_one (14) 、 Dye lignin (15), dye lignin 7_0_ β - d_furanosyl_ (1 → 6) _0_ β - d_glucopyranoside (16), _ (4_ hydroxy_3 methoxyphenyl) _ 5_ ethoxydecan_3 _one (17), anti hydroxycinnamic acid (18), ethyl paraben (19), uridine (20). Among them, compounds 1 and 20 are alkaloids, compounds 2-15, 17-19 are phenolic acids, and compound 16 is a phenolic glycoside. Compounds 1~3 and 13~20 were isolated from purple rivet for the first time. The MTS method was used to evaluate the cell proliferation activity of compound 1 at concentrations greater than 25 0 μ mol/L can promote the proliferation of RAW 264.7 macrophages.  alkaloids; phenolic constituents; Butea monospermae Hongfang Li PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
