Abstract
Endophytes of Panax have the potential to produce their host plant secondary metabolites, ginsenosides. Panax sokpayensis, an endemic traditional medicinal plant of the Sikkim Himalayas was explored for the isolation of endophytic fungi. In the present study, we have isolated 35 endophytic fungal cultures from the rhizome of P. sokpayensis and screened for ginsenosides production by HPLC by comparing the peak retention time with that of standard ginsenosides. The HPLC analysis revealed that out of 35 isolates, the mycelial extracts of four fungal endophytes (PSRF52, PSRF53, PSRF49 and PSRF58) exhibited peaks with a similar retention time of the standard ginsenoside, Compound K (CK). LC-ESI-MS/MS analysis led to the confirmation of ginsenoside CK production by the four fungal endophytes which showed a compound with m/z 639.6278, similar to that of standard ginsenoside CK with yield in potato dextrose broth flask fermentation ranging from 0.0019 to 0.0386 mg/g of mycelial mass in dry weight basis. The four prospective fungal endophyte isolates were identified as Thermothielavioides terrestris PSRF52, Aspergillus sp. PSRF49, Rutstroemiaceae sp. strain PSRF53, and Phaeosphaeriaceae sp. strain PSRF58 based on ITS sequencing. The present finding highlights the need for further study on growth optimization and other culture parameters to exploit the endophytes as an alternative source for ginsenoside CK production.

Abstract
Four new isolates including one new butanediamide glycoside (1), one new flavonoid glycoside (2) and two new flavonone glycosides (3, 4) were identified from the leaves and stems of Panax quinquefolius, among which 1 possessed the firstly reported N,N'-(5-hydroxy-1,3-phenylene) butanediamide skeleton with an unique 6/9 ranged dual-ring structure. The structures were elucidated by the NMR data, ECD analysis and chemical acid hydrolysis. All the compounds (1-4) were tested for their cytotoxicity against two human cancer cell lines of HepG2, A549 and HCT116 by the MTT method. Outstandingly, compound 1 exhibited targeted inhibitory proliferation of HCT116 cell with IC50 value of 12.1 μM, whereas compounds 3 and 4 exhibited targeted inhibitory proliferation of HepG2 cell with IC50 values of 15.3 and 17.3 μM, as well as no obvious cytotoxicity of compounds 1-4 against A549.
