| Nat Prod Res. 2017 Jun;31(11):1333-1338. | | Biological activities of triterpenoids from Poraqueiba sericea stems.[Pubmed: 27736194] | Eleven compounds were isolated from Poraqueiba sericea stems and identified as niga-ichigoside-F1 (1), trachelosperoside B1 (2), 4-epi-niga-ichigoside (7), 19α-hydroxyasiatic acid (3), myrianthic acid (4), hyptatic acid (5), trachelosperogenin B (6), arjunolic acid (8), and trachelosperogenin E (9), secologanoside (10) and secoxyloganin (11).
METHODS AND RESULTS:
Compounds 1-11 were tested for their antileishmanial activities against Leishmania infantum promastigotes, 1-6 and 8-11 were tested for their cytotoxic activities on fibroblasts, 1-3, 5-6, 8-11 were evaluated for their anti-elastase and anti-acetylcholinesterase assays activities by a spectrophotometric method and 1-2, 5 and 7-10 were tested using bioautography for their β-glucosidase.
CONCLUSIONS:
No antileishmanial activity was detected; compounds 1, 2 and 11 showed a moderate cytotoxic activity with IC50 17.7, 20.5 and 10.9 μg/mL, respectively; compounds 2, 8, 9 and 10 gave a percentage of inhibition ranging from 13 to 16% (at 50 μg/mL) and compounds 1 and 2 showed an inhibition zone on β-glucosidase and anti-acetylcholinesterase assays. | | Zhongguo Zhong Yao Za Zhi. 2006 Nov;31(22):1875-9. | | Triterpenes from herb of Potentilla chinesis.[Pubmed: 17285988] |
METHODS AND RESULTS:
Five pentacyclic triterpenoids, oleanolic acid (1), hederagenin (2), ursolic acid (3), tormentic acid (4) and myrianthic acid (5), were isolated from the methanol extract of the leaves of Campsis grandiflora, and structures of the compounds were established by the spectroscopic methods. Compounds 2, 3, 4, and 5 were isolated for the first time from the genus Campsis.
CONCLUSIONS:
All of the compounds (IC50: 45.3, 32.8, 82.6, 42.9 and 46.2 microM respectively) were as equivalently inhibitive as acetylsalicylic acid (IC50: 57.0 microM) on epinephrine induced platelet aggregation. | | Arch Pharm Res. 2004 Apr;27(4):376-80. | | Anti-platelet pentacyclic triterpenoids from leaves of Campsis grandiflora.[Pubmed: 15180300] |
