The quality and quantity of medicinal plants are serious issues for the pharmaceutical and dietary supplement industries. Traditionally, this material has been harvested from the wild, and while cultivation procedures have been developed for supplements such as St. John’s Wort, this is still the general method employed for the majority of medicinal plants. Increasing public demand for these pro...

Approximately 15 ml. of venous blood were withdrawn and expressed into a chilled tube containing 0.30 ml. (300 U.S.P. units) of sodium heparin solution. After thorough but gentle stirring, 10.0 ml. were transferred by Folin pipette to 10 ml. of ice cold 10 per cent trichloroacetic acid. The mixture was thoroughly homogenized with a heavy stirring rod and centrifuged in the cold. The supernatant...

Purpose: Podophyllum hexandrum Royle, a source of highly valued podophyllotoxin has been subjected to heavy collection from the wild. The ever-increasing demand of podophyllum is mainly due to two semi synthetic derivatives of podophyllotoxin that is etoposide and teniposide, which are used in the treatment of various types of cancer. The anti cancer lignan derivative podophyllotoxin in Podophy...

Recent molecular phylogenetics have indicated that American mayapple (mainly self-incompatible, SI) and Himalayan mayapple, which was considered to be self-compatible (SC), are sister species with disjunct distribution between eastern Asia and eastern North America. We test a hypothesis that the persistence of this earlyspring flowering herb in the Himalayan region is attributable to the transi...

Cervical dysplasia, a premalignant lesion that can progress to cervical cancer, is caused primarily by a sexually transmitted infection with an oncogenic strain of the human papillomavirus (HPV). The HPV infections are treated through destroying the clinical lesions: laser, cryotherapy, podophyllin... The hope is that by causing local tissue inflammation that the body will be stimulated to moun...

T he wine grape, Vitis vinifera, is a member of the Vitaceae, a family of vigorous, climbing, woody plants that live in the Northern Hemisphere. The plants are illadapted to tropical climates, and thus never crossed the equator (except those transported by humans, which are cultivated in Argentina, Chile, Australia, South Africa, and other regions in the Southern Hemisphere). The genus Vitis co...

6~ Secretion and Composit ion of H u m a n Bi le bile. Later he mixed with the food on one occasion 1 gramme of calomel. H. Nasse concludes from his results that calomel increases the total quantity of bile secreted, but that it diminishes its solids. Koelliker and Mueller* experimented on a dog with a permanent biliary fistula. They studied the effect of calomel, and to some extent also of alo...

Podophyllum emodii, Taxus brevifolia, Ochrosia elliptica and Campototheca acuminata, have provided active principles, used to control advanced stages of several malignancies in clinical settings. Most of these chemotherapeutic agents have been reported to exhibit severe normal tissue toxicity, accompanied by undesirable side effects. Further many of the potent antineoplastic drugs are highly ex...
