Abstract:

In order to study the chemical compounds of the calli induced from Maytenus hookeri, the dried and fresh cells of the calli were extracted by heat refluxing and cold soaking method, respectively. The chemical constituents were purified through various column chromatography including silica gel, RP-18 and Sephadex LH-20 from the ethyl acetate extract. According to the NMR and MS analysis, sixteen compounds were identified as wilforlide A (1), wilforlide B (2), 3β,22α-dihydroxyolean-12-en-29-oic acid (3), 22α-hydroxy-3-oxoolean-12-en-29-oic acid (4), 3-epikatonic acid (5), oleana-9(11),12-dien-3-β-ol (6), 22α-hydroxy-3-oxo-12-ursen-30-oic acid (7), triptotriterpenic acid C (8), 2α,3β-dihydroxy-29-friedelanoic acid (9), maytenonic acid (10), 3β-hydroxystigmast-5-en-7-one (11), 7β-hydroxysitosterol (12), stigmast-4-ene-3-one (13), β-sitosterol (14), 1-β-D-glucpotyransyl-2,6-dimetoxi-4-propenyl-benzene (15) and adenosine (16). All compounds were reported in the calli of M. hookeri and the plant for the first time except 10 and 14.
