Two new labdane diterpene glycosides from flowers of Baccharis medullosa DC.
From the flowers of Baccharis medullosa DC (Asteraceae) two new ent-labdane-type diterpene glycosides were isolated. Structures were established by application of various spectroscopic techniques. The sugar residues were identified after acid hydrolysis of the isolated products.

متن کاملLabdane-type diterpenoids from the fruits of Vitex trifolia.
Seven new labdane-type diterpenoids, vitextrifolins A-G (1-7), along with eight previously reported analogues, were isolated from the fruits of Vitex trifolia. The structures of 1-7 were elucidated by spectroscopic data interpretation. The isolates were evaluated for their cytotoxicity against four human cancer cell lines (A549, HCT116, HL-60, and ZR-75-30), but all were inactive (IC(50) < 5 μg...
متن کاملClerodane and labdane diterpene glycosides from a Malagasy endemic plant, Cussonia racemosa.
Four clerodane glycosides, cussosides A-D, and one labdane glycoside, cussoside E were isolated from the dried leaves of Cussonia racemosa, along with two known flavonol glycosides identified as rutin and kaempferol rutinoside. The structures of the compounds were deduced on the basis of their physical and spectral data.
متن کاملIridoid and Furanolabdane -Type Diterpene Glycosides from Rhizomes of Eremostachys azerbaijanica Rech. f.
Background and objectives: The rhizomes of Eremostachys azerbaijanica Rech. f.,as an indigenous plant in East Azerbaijan province of Iran, were studied for isolation and identification of possible phytoconstituents. Methods: The air- dried and ground rhizomes were extracted with n-hexane, dichloromethane (DCM) and methanol (MeOH) using a Soxhlet appara...
