UNLABELLED • PREMISE OF THE STUDY The development of microsatellite primers in the endangered species Dracaena cambodiana will be the foundation for genetic and conservation studies of D. cambodiana and several Dracaena species. • METHODS AND RESULTS A total of 26 microsatellite markers were developed in Chinese populations of D. cambodiana, using the Fast Isolation by AFLP of Sequences Con...

Dracophane, a novel structural derivative of metacyclophane, was isolated from the resin of Dracaena cinnabari Balf. The structure of this compound was determined by spectroscopic methods to be 3,12,21-trihydroxy-1,10,19-tris(4-hydroxyphenyl)-5,14,23-trimethoxy[3.3.3]metacyclophane.

BACKGROUND Infertility is a common complication in diabetic men and experimental animals, mainly due to loss of germ cells by apoptotic cell death. The aim of this study was to evaluate the effects of aqueous and ethanol extracts of Dracaena arborea in streptozotocin-induced ultra-structural spermatogenic alterations in Wistar rats. METHODS Diabetic animals were orally treated with Millipore ...

A morphologically distinct element of the group of Dracaena species from Thailand and Burma with undifferentiated leaf sheaths, no leaf blade central costa, free tepals and free thickened filaments known as Chan nuu or Chan pha krai in Thai is shown to be a distinct species, Dracaena kaweesakii Wilkin & Suksathan based on habit, leaf base and margin, inflorescence axis indumentum and floral cha...

Most lizards feed on a variety of food items that may differ dramatically in their physical and behavioral characteristics. Several lizard families are known to feed upon hard-shelled prey (durophagy). Yet, specializations toward true molluscivory have been documented for only a few species. As snails are hard and brittle food items, it has been suggested that a specialized cranial morphology, ...

Dragon's blood is a deep red resin which has been used for centuries by many cultures and much prized for it's rarity, depth of colour and alchemical associations. The original source of dragon's blood resin is believed to be Dracaena cinnabari from Socotra in Africa, but since mediaeval times there have been several alternatives from different geographical locations from the Canary Islands to ...

Dragon's blood is a red resin mainly extracted from Dracaena plants, and has been widely used as a traditional medicine in East and Southeast Asia. The major components of dragon's blood are flavonoids. Owing to a lack of Dracaena plants genomic information, the flavonoids biosynthesis and regulation in Dracaena plants remain unknown. In this study, three cDNA libraries were constructed from th...

The MeOH extract of Dracaena viridiflora was found to display significant cytotoxicity against some cancer cell lines. Systematic phytochemical investigation of this extract led to the isolation and structure elucidation of ten secondary metabolites including five spirostane (1-5) and one furostane (6) steroidal saponins. Furthermore, some acetylated spirostane analogues and three previously un...

Few of the about 190 species currently described in plant genus Dracaena [...]

Permintaan dracaena dari luar negeri terus meingkat dan belum terpenuhi. Indonesia memiliki kesesuaian iklim lahan untuk ditanami tanaman hias dracaena. Produksi dalam masih rendah menunjukan trend fluktuatif, salah satu penyebabnya adalah penanganan resiko yang optimal. Tujuan penelitian ini mengidentifikasi risiko menangani sesuai pada usaha Dracaena di PT. STU. Desain digunakan desain kualit...
