(Z)-3-Hexenyl diglycosides from Spermacoce laevis Roxb.

Abstract

A new (Z)-3-hexenyl O-b-D-glucopyranosyl-(1 fi 6)-b-D-glucopyranoside was isolated from the aerial part of Spermacoce laevis, along with 17 known compounds:phenyethyl O-a-L-rhamnopyranosyl-(1 fi 6)-b-D-glucopyranoside, benzyl O-a-Larabinopyranosyl-(1 fi 6)-b-D-glucopyranoside, benzyl O-b-D-xylopyranosyl-(1 fi 6)-b-D-glucopyranoside, asperuloside, 6a-hydroxyadoxoside, asperulosidic acid, kaempferol 3-O-b-D-glucopyranoside, kaempferol 3-O-rutinoside, quercetin 3-O-b-D-galactopyranoside, quercetin 3-O-a-L-rhamnopyranosyl-(1 fi 6)-b-D-galactopyranoside, and rutin. The structure determinations were based on physical data and spectroscopic evidence.

Borreria and Spermacoce species (Rubiaceae): A review of their ethnomedicinal properties, chemical constituents, and biological activities

“…and S. assurgens Ruiz and Pavon) is a small herb found in the tropical regions of Asia. [ 28 ] Also occurs in Mexico, where decoction of the leaves is used to treat kidney pain and prevent menstruation[ 29 ] while the entire plant in admixture with Cuscuta L. and Zebrina pendula Schum is used for amenorrhea in Jamaica[ 30 ] and West India. [ 31 ] In Jamaica, the tea of the entire plant boiled with Desmodium Desv.…”

Three new olefinic acetogenin glycosides from leaves of Staphylea bumalda DC.

“…The present paper describes the isolation and structure determination of three new olefinic acetogenin glycosides (3, 6 and 7) and four known C 6 aliphatic glycosides; n-hexyl b-D-gentiobioside (1) [2], (E)-2-and (Z)-3-hexenyl b-Dglucosides (2 and 4) [3] and (Z)-3-hexenyl O-b-D-glucopyranosyl-(1 00 ? 6 0 )-b-D-glucopyranoside (5) [4], from the leaves of the title plant.…”

Chemical constituents from Oldenlandia corymbosa L. of Thai origin

“…However, there are a few reports on the presence of other types of compounds, particularly anthraquinones [6] and triterpenoids [7,8]. As part of our further continuing studies on Rubiaceous plants [9][10][11][12][13], we investigated the chemical constituents of this plant collected from Thailand. This paper describes the isolation and identification of ten polar constituents, including eight iridoid glucosides (1)(2)(3)(4)(5)(6)(7)(8) The dried whole plants of O. corymbosa (1.7 kg) were macerated with MeOH.…”
