A new pyranoxanthone from Garcinia nervosa.
    Natural product research, 2017, Volume: 31, Issue:21

    Phytochemical studies on the stem bark of Garcinia nervosa has resulted in the discovery of one new pyranoxanthone derivative, garner xanthone (1) and five other compounds, 1,5-dihydroxyxanthone (2), 6-deoxyisojacareubin (3), 12b-hydroxy-des-D-garcigerrin A (4) stigmasterol (5), and β-sitosterol (6). The structures of these compounds were elucidated with the aid of spectroscopic techniques, such as NMR and MS. The crude extracts of the plant were assessed for their antimicrobial activity.

[Chemical constituents of Cudrania cochinchinensis].
    Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2013, Volume: 36, Issue:9

    To study the chemical constituents of Cudrania cochinchinensis.. Compounds were isolated and purified by silica gel column, sephadex LH-20 chromatography and recrystallization. Their structures were elucidated by physicochemical properties and spectral data.. Thirteen compounds were isolated from the 70% ethanol extract of the root of Cudrania cochinchinensis and identified as beta-sitosterol (1), butyrospermol (2), butyrospermol acetate (3), (+) syringarenol (4), 1, 3, 6-trihydroxy-7-methoxy xanthone (5), 1, 3, 6, 7-tetrahydroxy-8-prenylxanthone (6), kaempferol (7), dihydrokaempferol (8), umbelliferone (9),4-hydroxybenzyl ethyl ether (10), 2,4-dihydroxybenzaldehyde (11), 4-hydrox-ybenzaldehyde (12) and vanillin (13).. Compounds 2 - 6, 10 - 13 are isolated from Cudrania cochinchinensis for the first time.

[Chemical constituents from barks of Garcinia tetralata].
    Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2008, Volume: 33, Issue:20

    To study the chemical constituents of the barks of Garcinia tetralata.. Compounds were isolated and purified repeatedly by silica gel and ODS column chromatography and their chemical structures were elucidated by their physicochemical properties and spectral data analysis.. Ten compounds were obtained and identified as 1, 7-dihydroxyxanthone (1), buchanaxanthone (2), garciniaxanthone H (3), 1, 2, 5-trihydroxyxanthone (4), subelliptenone H (5), 6-desoxyjacareubin (6), 6-deoxyisojacreubin (7), subelliptenone G (8), methyl orsellinate (9) and beta-sitosterol (10).. Compounds 1-10 were isolated from this plant and compound 9 was obtained from the genus Garcinia for the first time.
