[Chemical consitituents from root of Isatis indigotica].[Pubmed:23944031]

Zhongguo Zhong Yao Za Zhi. 2013 Apr;38(8):1172-82.

Thirty-three compounds were isolated from the root decoction of Isatis indigotica by using a combination of various chromatographic techniques including silica gel, macroporous adsorbent resin, Sephadex LH-20, and reversed-phase HPLC. Their structures were elucidated by spectroscopic data as (+)-dehydrovomifoliol (1), (S)-(+)-abscisic acid (2), vomifoliol (3), cyclo (L-Phe-L-Leu) (4), cyclo(L-Phe-L-Tyr) (5), cyclo(L-Tyr-L-Leu) (6), cyclo(L-Pro-L-Tyr) (7), Evofolin B (8), (+)-syringaresinol (9), (-)-(7R,7'R,8S,8'S)-4,4'-dihydroxy-3-methoxy-7,9';7',9-diepoxy-lignan (10), (-)-medioresinol (11), (+) -(7R,7'R,8S,8'S) -neo-olivil (12), (-) -5-methoxyisolariciresinol (13), 1,3-dihydro-2H-indol-2-one (14), isalexin (15), dihydroneoascorbigen (16), indican (17), (-) -(S) -cyanomethyl-3-hydroxyoxindole (18), isoformononetein (19), calycosin (20), stigamast-5-ene-3beta-ol-7-one (21), acetovanillone (22), 3, 5-dimethoxy-4-hydroxyacetophenone (23), dihydroconiferyl alcohol (24), dihyroferulic acid (25), 3-hydroxy-1-(4-hydroxyphenyl) propan-1-one (26), beta-hydroxypropiovanillone (27), 4-aminobenzoic acid (28), 3-(4-hydroxyphenyl) propan-1-ol (29), 4-(2-hydroxyethyl) phenol (30), 2-methoxy-4-vinylphenol (31), pyrocatechol (32), and 4-pentenamide (33). These compounds were isolated from the root of I. indigotica for the first time. In preliminary in vitro assays, compound 19 showed activity against the influenza virus A/Hanfang/359/95 (H3N2), the herpes simplex virus 1 (HSV-1), and Coxsackie virus B3 (Cox-B3), with IC50 values of 2.06, 6.84, and 8.70 micromol x L(-1), respectively, but other compounds were in-active at a concentration of 1.0 x 10 x (-5) mol x L(-1).

Phenolic compounds obtained from stems of Couepia ulei with the potential to induce quinone reductase.[Pubmed:15022717]

Arch Pharm Res. 2004 Feb;27(2):169-72.

Activity-guided fractionation of the EtOAc-soluble extract of the stems of Couepia ulei, using a bioassay based on the induction of quinone reductase (QR) in cultured Hepa 1c1c7 mouse hepatoma cells led to the isolation of two active compounds, a new natural product, erythro-2,3-bis(4-hydroxy-3-methoxyphenyl)-3-ethoxypropan-1-ol (1), and a known compound, evofolin-B (2), along with five inactive compounds all of known structure, viz., betulinic acid, oleanolic acid, pomolic acid, (+/-)-syringaresinol, and ursolic acid. These isolates were identified by analysis of physical and spectral data. Compounds 1 and 2 exhibited QR inducing activity, with observed CD (concentration required to double induction) values of 16.7 and 16.4 microM, respectively.

[Chemical constituents of stems and branches of Adina polycephala].[Pubmed:20707194]

Zhongguo Zhong Yao Za Zhi. 2010 May;35(10):1261-71.

OBJECTIVE: To investigate chemical constituents of the stems and branches of Adina polycephala and their pharmacological activities. METHOD: The constituents were isolated by a combination of various chromatographic techniques including column chromatography on silica gel, Sephadex LH-20, and C-18, as well as reversed-phase HPLC. Structures of the isolates were identified by spectroscopic data analysis. In vitro cytotoxic, anti-inflammatory, anti-oxidant, anti-HIV, neuroprotective and anti-diabetic activities were screened by using cell-based models. RESULT: Twenty-eight constituents were isolated. Their structures were identified as clemochinenoside B (1), kelampayoside A (2), osmanthuside H (3), 4-hydroxy-3-methoxyphenol-beta-D-[6-O-(4-hydroxy-3,5-dimethoxylbenzoate)]-glucopy ranoside (4), and syringic acid beta-D-glucopyranosyl ester (5). Ten iridoidal glycosides: geniposidic acid (6), geniposide (7), 6beta-hydroxygeniposide (8), 6beta-hydroxygeniposide (9), ixoside (10), ixoside 11-methyl ester (11), 11-methyl forsythide (12), 7beta-hydroxysplendoside (13), gardoside (14) and mussaenosidic acid (15), (+) -pinoresinol (16), (+) -medioresinol (17), (+) -syringaresinol (18), (-)-lariciresinol (19), evofolin-B (20), alpha-hydroxyacetovaillone (21), syringic acid (22), vanillin (23), 3, 4, 5-trimethoxyphenol (24), and 2,6-dimethoxy-1, 4-benzoquinone (25), beta-sitosterol (26), mannitol (27), and daucosterol (28). At a concentration of 1.0 x 10(-5) mol x L(-1), these compounds were inactive in the assays, including cytotoxicity against human tumor cell lines (HCT-8, Bel-7402, BGC-823, A549 and A2780), anti-inflammatory activity against the release of beta-glucuronidase in rat polymorphonuclear leukocytes (PMNs) induced by platelet-activating factor (PAF), antioxidant activity in Fe(2+)-cystine-induced rat liver microsomal lipid peroxidation, anti-HIV activity against HIV-1 replication, neuroprotective activity against serum deprivation or glutamate induced neurotoxicity in cultures of PC12 cells, and the inhibitory activity against protein tyrosine phosphatase 1B (PTP1B). CONCLUSION: Compounds 1-20 were obtained from the genus Adina for the first time. The 13C-NMR data of compounds 10 and 11 were reassigned. A further evaluation of pharmacological activity of these compounds is expected.
