Chemical Examination of Podophyllum emodi Wall. var. hexandrum (Royle)

Journal of the American Pharmaceutical Association (Scientific ed.), 1954
Resin of Podophyllum emodi Wall. was isolated. It contains an essential oil responsible for its odor. The resin contains podophyllotoxin (32 per cent), picropodophytlin (0.33 per cent), and six per cent of the yellow coloring matter quercetin. The resin also contains traces of a phenolic compound other than quercetin.

Chromosome complement and nucleolar organization in Podophyllum hexandrum Royle

Genetica, 1990
The karyomorphology of Podophyllum hexandrum Royle (2n=2x=12) is described for the first time. The haploid set comprises one metacentric, three sub-metacentric and two acrocentric chromosomes. Metacentrics are the longest and acrocentrics the smallest in the complement.

Molecular characterization and marker based chemotaxonomic studies of Podophyllum hexandrum Royle

Fitoterapia, 2010
Detailed chemical studies and RAPD analysis were done in different populations of Podophyllum hexandrum collected from high altitude regions of North Western Himalayas. Random amplified polymorphic DNA (RAPD) analysis revealed a high degree of genetic diversity among the 12 collected accessions, attributed to their geographical and climatic conditions.

Detection and identification ofPodophyllotoxin produced by cell cultures derived from podophyllum hexandrum royle

Plant Cell Reports, 1989
The phenylpropanoid derived lignan podophyllotoxin, occurring inPodophyllum species, is used as a starting compound for the chemical synthesis of the antitumour agents etoposide (VP-16-213) and teniposide (VM-26). At present, the availability of this lignan becomes increasingly limited.

Factors influencing podophyllotoxin production in adventitious root culture of Podophyllum hexandrum Royle

Acta Physiologiae Plantarum, 2014
To determine the possibility of generating the Podophyllotoxin accumulation using Podophyllum hexandrum adventitious roots derived from root segments, several nutrient constituents (carbon sources, media strength, initial medium pH, ammonium and nitrate proportion and phosphate ratio) were evaluated in culture.

GA3 induced flowering in Podophyllum hexandrum Royle: A rare alpine medicinal herb

Acta Physiologiae Plantarum, 2001
Podophyllum hexandrum Royle, an important alpine herb, is the source of highly valued podophyllotoxin. The effect of some plant growth substances (GA3, BAP & ABA), uniconazole (an inhibitor of GA biosynthesis), and a combination of GA3 and uniconazole were examined in respect to influence on sprouting in rhizomes of P.

An efficient in vitro system for somatic embryogenesis and podophyllotoxin production in Podophyllum hexandrum Royle

Protoplasma, 2014
Podophyllum hexandrum Royle known as Indian mayapple is an important medicinal plant found only in higher altitudes (2,700 to 4,200 m) of the Himalayas. The highly valued anticancer drug Podophyllotoxin is obtained from the roots of this plant. Due to over exploitation, this endemic plant species is on the verge of extinction.
