**11. Chemical composition**

Devkota [17] isolated 6 (six) compounds from *Paris polyphylla* collected from Parbat district Nepal.

The compounds are


A new saponin-polyphyllin A-H has been isolated from the rhizome of *Paris polyphylla* of which first six are spirostanol steroidal saponins and remaining two are furastanol steroidal saponins [18].

A novel steroidal saponin along with the 12 known compounds were separated from *Paris polyphylla* var. chinensis [19]. The novel compound was obtained as an amorphous solid and spectral data including two dimensional NMR showed the structure as 3b,21-dihydroxypregnane-5-en-20S-(22,16)-lactone-1-O-a-L-rhamnopyrnosyl(1®2)- [b-D-xylopyranosyl(1®3)]-b-D-glucopyranoside.The 12 known compounds are known steroids and their structures were identified by 13C NMR spectrum as
