Four acyclic diterpene glycosides were extracted from Habanero, the fruits of Capsicum chinense JACQ., which is known as one of the hottest peppers in existence. Two of these glycosides were identified as capsianoside XIII and capsianoside XV. The other two were new ones and were characterized as 3-O-beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl 17,19-dihydroxy-6E,10E,14Z-(3S)-geranyllinalool 17-O-beta-D-glucopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-[alpha-L-rhamnopyranosyl-(1-->6)]-beta-D-glucopyranoside and 3-O-beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl 6E,10E,14Z-(3S)-17-hydroxy-geranyllinalool 17-O-[3-O-beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl 6'E,10'E,14'Z-(3'S)-13'R,19'-dihydroxy-geranyllinalool-16'-oyl (16'-->2)-[alpha-L-rhamnopyranosyl-(1-->3)]-alpha-L-rhamnopyranosyl-(1-->4)-[alpha-L-rhamnopyranosyl-(1-->6)]-beta-D-glucopyranoside.
