Chemical Constituents and Cytotoxic Activities of Stem Bark of Dialium cochinchinense

Two New Prostaglandin‐Like Compounds from Callicarpa arborea Roxb and Their NLRP3 Inflammasome Activation Inhibitory Activity

“…Additionally, the structures of the known compounds were confirmed as 29‐Nor‐20‐oxolupeol ( 3 ), [24] pachypodol ( 4) , [25] chrysosplenetin B ( 5) , [26,27] genkwanin ( 6) , [28,29] velutin ( 7) , [30] and luteolin 7, 4 ′ –dimethyl ether ( 8 ), [31] by matching their spectral results with those available in the literature. All the compounds were isolated for the first time Callicarpa arborea Roxb.…”

“…The absolute configuration (9S13R) of compound 2 was confirmed by comparing its theoretical and experimental curves (Figure 5). Therefore, the structure of 2 was established and trivially named as Callicarboric acid B. Additionally, the structures of the known compounds were confirmed as 29-Nor-20-oxolupeol (3), [24] pachypodol (4), [25] chrysosplenetin B (5), [26,27] genkwanin (6), [28,29] velutin (7), [30] and luteolin 7, 4'-dimethyl ether (8), [31] by matching their spectral results with those available in the literature. All the compounds were isolated for the first time Callicarpa arborea Roxb.…”

Isolation of Various Flavonoids with TRAIL Resistance-Overcoming Activity from Blumea lacera

“…The EtOAc layer was also fractionated to obtain compounds 12-14 (Figure 1). Detailed NMR and mass spectrometry analysis identified the isolated compounds as pectolinargenin (1) [10], bonanzin (2) [11], velutin (3) [12], chrysosplenol B (4) [13], chrysosplenol C (5) [13], 4',5-dihydroxy-3',7-dimethoxyflavone (6) [14], cirsilineol (7) [15], eupatilin (8) [16], 3-demethoxycentaureidin (9) [17], jaceidin (10) [18], centaureidin (11) [19], patuletin 3-O-β-D-glucopyranoside (12) [20], patulitrin (13) [21], 6-methoxykaempferol 3-O-β-D-glucopyranoside ( 14) [22], 3-oxostigmasta-4,22E-diene (15) [23], 9-oxo-10E,12Zoctadecadienoic acid (16) [24], 3-hydroxy-octadeca-4E,6Z-dienoic acid (17) [25], and aurantiamide acetate (18) [26].…”
