Two new triterpene saponins were isolated from Lonicera bourneei Hemsl (Lonicera bourneei Hemsl), named as Southwest Lonicera Saponin A and Southwest Lonicera Saponin B. Their structures are 3 O β D Glucopyranosyl 2 3 Lipo Lupine 20 (29) Alkylene 2 8 Acids 2 8 O β D Glucopyranose, 3 O β D Glucopyranosyl 2 3 Hydroxyl lupeolane 2 0 (2 9) Alkylene 2 8 Acids 2 8 O [β D pyran Glucose-based (1→6) β D glucopyranose esters
