Description Seven hopane-type saponins were isolated from the methanol extract of Glinus lotoides. Six of them were identified as novel compounds and designated as lotoideside A [3-O-b-D-xylopyranosyl (1! 2)-a-L-rhamnopyranosyl-6a-O-b-D-xylopyranosyl-22-b-O-b-Dglucopyranosyl- 16b-hydroxy hopane (1)], lotoideside B [3-O-b-D-xylopyranosyl (1 !2)-a-L-rhamnopyranosyl-22-b-O-b-D-glucopyranosyl- 6a,16b-dihydroxyhopane (2)], lotoideside C [3-OD-xylopyranosyl-6a-O-b-D-xylopyranosyl-16b-O-b-D-xylopyranosyl-22bhydroxyhopane (3)], lotoideside D [3-O-b-D-xylopyranosyl-16b-O-a-L-arabinopyranosyl-6a,22-b-dihydroxyhopane (4)], lotoideside E [3-O-b-D-xylopyranosyl-6a-O-b-D-xylopyranosyl-16 b,22-b-dihydroxyhopane (5)], and lotoideside F [3-O-b-D-xylopyranosyl-22- b-O-b-D-glucopyranosyl-16b-hydroxyhopan-6-one (6)]. The known compound succulentoside B (7) was also encountered. Their structures were elucidated on the basis of one-and two-dimensional NMR spectroscopic techniques, ESIMS and chemical evidences. � 2005 Elsevier Ltd. All rights reserved.
