.Four new dammarane-type triterpenes were isolated for the first
time from nature, and this report is the first to identify this group of compounds from the Vitaceae
family. Seven compounds, viz., glycerolipids and squalene, stimulated ALP activity at a dose of 10 μg/ mL.
Moreover, the synergistic effect of these compounds on bone formation was demonstrated.
Conclusion: This report describes,for the first time,the isolation of active compounds from CQ hexane
extract; these active compound swill be useful for the quality control of extracts from this plant used to
treat osteoporosis.
