The genus Dipsacus is characterized by a remarkable bidirectional flowering sequence and a rare phyllotactic pattern. Considering that flower initiation and flowering sequence may be interconnected, we document the development of the head meristem in Dipsacus fullonum. Our results indicate a gradual change in the geometry of the head meristem beginning with a dome shaped stage, continuing with a remarkable widening in the middle part of the head meristem and ending in a spindle-like form. Quantitative data confirm that meristem expansion is higher in the middle part than at the base of the meristem. Likewise, the size of the flower primordia in the middle part of the young head is significa…

Glucose, fructose and saccharose metabolism in Dipsacus silvestris infected by Cucumber mosaic virus.

2007

Dipsacus silvestris Miller (or Fuller’s Teasel) (Dipsacaceae) showing stunting, chlorotic leaf mosaic and narrowing of the lamina, has been found for the first time in Italy naturally infected by Cucumber mosaic virus (CMV). This virus was detected in PAS-ELISA tests and molecularly characterized by applying RT-PCR, using specific primers for the movement protein gene of RNA3 (forward 5’ CTA GGC TTT CCA AGC TAC CAG 3’; reverse 5’ CTA AAG ACC GTT AAC CAC CTG C 3’). The content of glucose, fructose and saccharose, determined by HPLC analysis, was calculated in both healthy (h) and CMV-infected (i) D. silvestris plants during the chronic infection period. An higher content of these carbohydrat…

Newest Results on the Chemistry and Pharmacology of TCM Drugs Containing Triterpene and Steroid Saponins

2012

The aim of this review is to provide newest results in the chemistry, pharmacology, and clinical studies of saponins-containing TCM drugs, some of them being listed in the Chinese Pharmacopoeia. It appears that literature on triterpene saponins is more abundant than that of steroid saponins, and ginseng occupies a prominent position in the list. However, other TCM drugs are well documented in recent years belonging to the genera Astragalus, Gynostemma, Bupleurum, Clematis, Dipsacus, Platycodon, Gypsophila, Anemarrhena, Lonicera, Paris, Dioscerea, Tribulus, and Ophiopogon. From a Pharmacological point of view, the most relevant results have been obtained with the cancer-related activity and …
