| Phytochemistry. 2014 Dec;108:177-88. | | Terpenoids, flavonoids and caffeic acid derivatives from Salvia viridis L. cvar. Blue Jeans.[Pubmed: 25256822] | Three diterpenoids, 1-oxomicrostegiol (1), viroxocin (2), viridoquinone (3), were isolated from the roots of Salvia viridis L. cvar. Blue Jeans.
METHODS AND RESULTS:
Five known diterpenoids, microstegiol (4), 7α-acetoxy-14-hydroxy-8,13-abietadiene-11,12-dione (5; 7-O-acetylhorminone tautomer), 7α,14-dihydroxy-8,13-abietadiene-11,12-dione (6; horminone tautomer), ferruginol and salvinolonyl 12-methyl ether (7) were also found in the roots together with 1-docosyl ferulate (8), and a mixture of 2-(4'-alkoxyphenyl) ethyl alkanoates (9).
CONCLUSIONS:
Two lupane triterpenoids, 2α-acetoxy-lup-20(29)-en-3β-ol (10), and 3β-acetoxy-lup-20(29)-en-2α-ol (11) were found in the aerial parts together with known compounds, Lup-20(29)-ene-2alpha,3beta-diol (12), ursolic acid, oleanolic acid, β-sitosterol and β-sitosterol glucoside. | | Zhongguo Zhong Yao Za Zhi. 2013 Jan;38(2):204-7. | | Chemical constitunents of seeds of Oroxylum indicum.[Pubmed: 23672042] | | Twenty compounds were isolated and purified by silica gel, and Sephadex LH-20 column chromatography, and their structures were determined by spectroscopic analysis including NMR and MS.
RESULT:
Twenty compounds were isolated and identified as oroxin A (1), oroxin B (2), chrysin (3), baicalein (4), quercetin (5), apigenin (6), kaempferol (7), quercetin-3-O-ara-binopyranoside (8), lupeol C9), Lup-20(29)-ene-2alpha,3beta-diol (10), pinosylvin (11), dihydropinosylvin (12), cholest-5-ene-3, 7-diol (13), rengyol (14), isorengyol (15), zarzissine (16), (E) -pinosylvin-3-O-beta-D-glucopyranoside (17), adenosine (18), sitosterol (19) and daucosterol (20).
CONCLUSION:
Compounds 11-13 and 15-18 were obtained from the genus Oroxylum for the first time, and except compound 18, the remaining 6 compounds were obtained from the family Bignoniaceae for the first time. |
