A new water-soluble saponin (esculentoside H) has been isolated from the roots of Phytolacca esculenta and identified as 3-O-[beta-D-glucopyranosyl-(1----4)-beta-D-xylopyranosyl]-28-O-beta-D- glucopyranosyl phytolaccagenin.
Two triterpenoidal saponins having phytolaccagenin as the aglycone were isolated from the roots of Phytolacca esculenta (Phytolaccaceae). The structures of two new saponins, esculentoside I and esculentoside N, were established to be 3-O-[beta-D-glucopyranosyl-(1----4)-beta-D-
Background: Esculentosides and related phytolaccosides form a group of oleanene-type saponins isolated from plants of the Phytolaccaceae family, essentially Phytolacca esculenta, P. americana and P. acinosa. This chemical family offers a
Follicular atresia is one of the main processes for the loss of granulosa cells and oocytes from the mammalian ovary and any impairment to premature ovarian failure. Large numbers of studies have demonstrated that granulosa cell apoptosis causes follicular atresia, yet the rescue of these cells
