Studies on the acyl glycosides from Leucoseptrum japonicum (Miq.) Kitamura et Murata.

Chemical and biological investigation of someClerodendrumspecies cultivated in Egypt

“…Compounds f1-f3 ( Figure 1) were identified as verbascoside and isoverbascoside by comparing their obtained physicochemical and spectral data with published data (Cooper et al, 1980;Andary et al, 1982;Miyase et al, 1982Miyase et al, , 1991Calis et al, 1984;Grande et al, 1985;Sasaki, et al 1989;Liu et al, 1992;Hazekamp et al, 2001;Kim et al, 2001;Kanchanapoom et al, 2002). Compounds b1-b3 ( Figure 1) were identified as cornoside, decaffeoylverbascoside and icariside B 5 (Jensen et al, 1973;Aasen et al, 1974;Endo & Hikino, 1984;Miyase et al, 1988;Kuwajima et al, 1993;Hase et al, 1995;Kanchanapoom et al, 2002).…”

Phenolic glycosides from Barnettia kerrii

“…The fraction eluted with MeOH was repeatedly chromatographed on columns of silica gel, . Fifteen were identified as known compounds; verbascoside (1), isoverbascoside (2), leucosceptoside A (3) (Miyase et al, 1982), luteoside A (6), luteoside B (7) (Kernan et al, 1998), 2 00 -O-apiosylverbascoside (8) (Kanchanapoom et al, 2001), decaffeoylverbacoside (9) (Karasawa et al, 1986), seguinoside K (10) (Zhong et al, 1999) (Achenbach et al, 1992) (Binns et al, 1987), (6S,9R)-roseoside (17) (Otsuka et al, 1995) rengyoside B (18) (Seya et al, 1989) and stegioside III (19) (Nass and Rimpler, 1996) by comparison of physical data with literature values and from spectroscopic evidence.…”

Lignan glucosides from Acanthus ilicifolius

“…The fraction eluted with 60% MeOH was repeatedly subjected to column chromatography using silica gel, and octadecylsilyl silica gel, then by HPLC±ODS to a ord ten compounds (1±10). Eight were known compounds; (+)-lyoniresinol 3a-O-b-glucopyranoside (1), (-)-lyoniresinol 3a-O-b-glucopyranoside (2) (Achenbach et al, 1992), alangilignoside C (5) (Yuasa et al, 1997) (Ida et al, 1994), (+)-syringaresinol-O-b-glucopyranoside (7) (Kobayashi et al, 1985), verbascoside (8) (Miyase et al, 1982), b-hydroxyacteoside (9) (Kitakawa et al, 1984) and plucheoside B (10) (Uchiyama et al, 1989) by physical data and spectroscopic evidence.…”
