P.pseudo-ginseng Wall, subsp. himalaicus Kara and its varieties var. angustifolius (Burk.) Li and var. bipinnatifidus (Seem.) Li (79) [Himalayan Panax, wild in the Eastern Himalayas). 

A Chinese-Japanese cooperative chemical study 104) of the rhizomes of this plant from Zhaotong, Yunnan at 2100m led to isolation of the oleanolic acid saponins, G-IV, C-IVa, and C-V in yields of 3.4, 2.8, and 3.1%. In this respect, then Zhujie-shen is very similar to Japanese Chikusetsu-ninjin. However, the composition of the dammarane saponin fraction of Zhujie-shen which consisted of Rd (0.04% yield). Re (0.12%), Rgi(0.15%), Rg (0.05%), NG-R2(0.02%, see Chapter VIII-2, Table II) and pseudo-ginsenoside-Fii (PG-Fn, 0.04%, an ocotillol-type saponin from leaves of Himalayan Panax and also from leaves of American Ginseng, see Chapter IX-2), was significantly different from that of the Japanese plant.
