Lignans and phenylpropanoids from the liquid juice of .

Seven lignans and eight phenylpropanoids, including one new lignan, 7,8,8'-5,5'-dimethoxyariciresinol-4----glucopyranoside (), were isolated from the liquid juice of . Their structures were established by extensive spectroscopic analyses. The absolute configuration of the new compound was determined by comparing its experimental electronic circular dichroism (ECD) spectra with calculated ECD spectra.

[Regeneration of Phyllostachys heteroclada and its relations with rhizome carbon- and nitrogen metabolism].

In order to search for the ways to restrain the flowering process and promote the regeneration of bamboo (Phyllostachys heteroclada), five types of regeneration experiments were conducted, including 1) harvesting all the bamboos in the first year and the flowered bamboos in the next year all at the beginning stage of florescence, 2) harvesting the flowered bamboos at the beginning stage of florescence in two consecutive years, 3) harvesting the fully flowered bamboos in the first year and the bamboos at the beginning stage of florescence in the next year, 4) fertilizing the bamboo floor before growing season in consecutive two years, and 5) no any manipulation. In each of the cases, the carbon- and nitrogen metabolism and related enzyme activities in bamboo rhizome were studied. The results showed that treatment 1 had the best effect, which resulted in the greatest number (207) of new shoots produced and with the highest survival rate (69.
