Podophyllum hexandrum Royle (=Sinopodophyllum hexandrum) is a high-altitude medicinal plant exploited for its etoposides which are potential anticancer compounds. An effective, conventional propagation method is by seed. However, seed germination is erratic, and seedling survival is low.

Fifty plants of Podophyllum hexandrum were collected from the interior ranges of western Himalaya of India from 8000 to 10000 ft above mean sea level for the analysis of podophyllotoxin content using HPLC. Two methods were used for the extraction of podophyllotoxin from powdered roots to standardize an extraction procedure for getting high yield of ...

Abstract The objective of this study was to establish a simple and efficient method for high frequency of somatic embryogenesis and plant regeneration of Podophyllum hexandrum and podophyllotoxin (PTOX) production. Embryogenic callus (100 mg FW) cultured on 0.75 strength MS medium with 4% sucrose and 3 g/l PVP produced maximum number of somatic ...

In order to improve the production of the cytotoxic lignan podophyllotoxin, seven precursors from the phenylpropanoid-routing and one related compound were fed to cell suspension cultures derived from the rhizomes of Podophyllum hexandrum Royle. These cell cultures were able to convert only coniferin into podophyllotoxin, maximally a 12.8 fold increase

An efficient Agrobacterium-mediated genetic transformation method has been developed for the medicinal plant Podophyllum hexandrum Royle, an important source of the anticancer agent podophyllotoxin. Highly proliferating embryogenic cells were infected with Agrobacterium tumefaciens harbouring pCAMBIA 2301, which contains npt II and gusA as selection ...

ABSTRACT Carbon dioxide and water vapor exchange at different levels of photosynthetically active radiation and temperature were measured in alpine and temperate populations of Podophyllum hexandrum Royle. The photosynthesis rate and stomatal conductance were high in alpine population irrespective of the temperature and the level of photosynthetically ...

Podophyllum hexandrum Royle, an important alpine herb, and a source of the highly valued aryltetralin-type lignan, podophyllotoxin, has been subjected to heavy collection from the wild due to ever increasing demand. The present study deals with an attempt to bring this plant under cultivation at a relatively lower altitude and to evaluate (1) various ...
