Four Novel Dammarane-Type Triterpenoids from Pearl Knots of Panax ginseng Meyer cv. Silvatica

Panax ginseng Meyer cv. Silvatica (PGS), which is also known as “Lin-Xia-Shan-Shen” or “Zi-Hai” in China, is grown in forests and mountains by broadcasting the seeds of ginseng and is harvested at the cultivation age of 15–20 years. In this study, four new dammarane-type triterpenoids, ginsengenin-S...

Descripción
Sumario:Panax ginseng Meyer cv. Silvatica (PGS), which is also known as “Lin-Xia-Shan-Shen” or “Zi-Hai” in China, is grown in forests and mountains by broadcasting the seeds of ginseng and is harvested at the cultivation age of 15–20 years. In this study, four new dammarane-type triterpenoids, ginsengenin-S1 (1), ginsengenin-S2 (2), ginsenoside-S3 (3), ginsenoside-S4 (4), along with one known compound were isolated from pearl knots of PGS. Ginsengenin-S2 significantly alleviated oxidative damage when A549 cells were exposed to cigarette smoke (CS) extract. In addition, ginsengenin-S2 could inhibit the CS-induced inflammatory reaction in A549 cells. Protective effects of ginsengenin-S2 against CS-mediated oxidative stress and the inflammatory response in A549 cells may involve the Nrf2 and HDAC2 pathways.
