Pinoresinol-lariciresinol reductase (PLR) is a key enzyme in podophyllotoxin (PTOX) biosynthesis pathway, which catalyzes the conversion of pinoresinol into secoisolariciresinol, central precursor for PTOX biosynthesis. Podophyllum peltatum an important anticancer species, and content obviously different from various plant organs. Therefore, investigation PLR gene expression facilitates underst...

Rhizome of red andong (Cordyline fruticosa (L.) A. Chev) is a medicinal plant that contains saponins known to be anti-inflammatory. The research aimed assess the anti-inflammatory activity rhizome ethanol extract andong. Phytochemical analysis was done qualitatively by using phytochemical reagents. Anti-inflammatory evaluated 25 Sprague Dawley male rats which had been divided into five groups: ...

Curcuma purpurascens Bl., belonging to the Zingiberaceae family, is known as temu tis in Yogyakarta, Indonesia. In this study, the hydrodistilled dried ground rhizome oil was investigated for its chemical content and antiproliferative activity against selected human carcinoma cell lines (MCF7, Ca Ski, A549, HT29, and HCT116) and a normal human lung fibroblast cell line (MRC5). Results from GC-M...

Bamboo species-the only herbaceous trees-have unique structural and physiological characteristics that differ from those of other tree taxa. However, the role of night-time water use in bamboo is poorly understood and has rarely been investigated. We studied the day- and night-time sap flow response to culm age and rhizome structure in three age levels (juvenile, mature, and senescent) of Phyll...

Ginger (Zingiber officinale Rosc.) rhizomes are popular as a spice and an herbal dietary supplement. The anti-inflammatory and anti-nausea qualities of ginger have applications in the pharmaceutical industry. Conventionally grown as a tropical field crop, ginger is plagued by soil-borne disease and nematode problems. Aeroponic cultivation of ginger can provide high-quality rhizomes that are fre...

The effects of acidic polysaccharides purified from Gastrodia rhizome on blood pressure and serum lipid levels in spontaneously hypertensive rats (SHR) fed a high-fat diet were investigated. Acidic polysaccharides were purified from crude polysaccharides by DEAE-Sepharose CL-6B. Thirty-six male SHR were randomly divided into three groups: Gastrodia rhizome crude polysaccharide (A), acidic polys...

Most cultured bamboos are perennial woody evergreens that reproduce from rhizomes. It is unclear why some rhizome buds develop into aerial bamboo shoots instead of new rhizomes. REVOLUTA (REV)-like Class III homeodomain leucine-zipper (HD-Zip) proteins and TEOSINTE BRANCHED1 (TB1)-like transcription factors have been shown to play regulatory roles in meristem initiation and outgrowth. We cloned...

Cerebral ischemia is known to produce brain damage and related behavioral deficits including memory. Recently, accumulating lines of evidence showed that dietary enrichment with nutritional antioxidants could reduce brain damage and improve cognitive function. In this study, possible protective effect of Zingiber officinale, a medicinal plant reputed for neuroprotective effect against oxidative...
