“…These terpenoids have been reported in studies about A. zerumbet oil composition, from different regions. 14 In addition, caryophyllene increase under in vitro conditions was up to 72% in relation to donor plants. Affonso et al,6 in studies about tissue cultures of Lantana camara, have also verified an increase in caryophyllene by addition of TDZ.…”

Volatiles produced by plantlets of Alpinia zerumbet were obtained by means of simultaneous distillation-extraction (SDE). The effects of indole-3-acetic acid, kinetin, thidiazuron and 6-benzylaminopurine on leaf and root volatile composition obtained by tissue cultures were investigated. A higher content of β-pinene and a lower content of sabinene were observed in leaf volatile of plantlets cultured in control, IAA and IAA+ TDZ media, as compared with those of donor plants. In vitro conditions were favorable to increase caryophyllene content. Volatile compounds from the root were characterized mainly by camphene, fenchyl-acetate and bornyl acetate; which constitute about 60% of total volatile.

“…O perfil químico de OEAZ obtido nesse estudo difere do previamente descrito para as folhas de A. zerumbet (Zoghbi et al, 1999;Ali et al, 2002). Entretanto, está em concordância com a descrição do monoterpeno terpinen-4-ol como o componente majoritário (Zoghbi et al, 1999;Ali et al, 2002). Zoghbi et al (1999) detectaram 1,8-cineol apenas nas flores da espécie, enquanto o limoneno, descrito como segundo componente majoritário por esses autores, não foi detectado no presente trabalho.…”

is traditionally employed to treat several diseases such as hypertension. The aim of this study was to evaluate the chemical composition, the anti-hypertensive activity and the capacity to reduce cardiac hypertrophy of the essential oil of A. zerumbet leaves (EOAZ) in rats. EOAZ was obtained through hydrodistillation in Clevenger apparatus and its chemical composition was analyzed by gas chromatography-mass spectrometry (GC-MS). Several constituents (14) were identified, terpen-4-ol (37.45%) being the major component, followed by caryophyllene oxide (7.56%), trans-sabinene hydrate (6.61%) and 1,8-cineol (4.02%). The cardiovascular effect was investigated after chronic treatment with spontaneously hypertensive rats (SHR) and their respective controls, Wistar-Kyoto rats (WKY). The treated group showed a lower mean arterial pressure (MAP) (SHRP: 160 ± 7 mm Hg; p<0.01) than the untreated group (SHR: 180 ± 5 mm Hg). The ratio of left ventricle-to-body weight (LV/BW) for SHRP was lower (2.504 ± 0.03 mg g -1 ; p<0.01) than that for SHR (2.162 ± 0.01 mg g -1 ), confirming the cardiac hypertrophy (CH) reduction. There were significant differences in MAP and CH between SHRP animals and control rats (WKY: 116 ± 2 mm Hg and WKYP: 119 ± 4 mm Hg; p<0.05.

“…Anti-inflammatory, bacteriostatic, and fungistatic properties were also reported. 37) It is proposed that DK could be metabolized by CYP450 to hispirin (Fig. 6), which differs from the methyl group of DK by the replacement of a hydroxyl group in the lactone ring, and two other additional hydroxyl groups at carbons 3 and 4 of the other benzene ring.…”

Total utilization of tropical plants Leucaena leucocephala and Alpinia zerumbet

In Okinawa, leucaena (Leucaena leucocephala de Wit) has great potential as animal feed for its high protein content, but its use has been limited owing to the presence of mimosine (b-[N-(3-hydroxy-4-pyridone)]-a-aminopropionic acid) which, when ingested, causes diseases in animals. A detoxifying enzyme, mimosinase, was purified from leucaena leaves and cDNA was cloned based on the amino acid sequence. During essential oil production and fiber isolation from alpinia (Alpinia zerumbet ), large volumes of solid and squeezed wastes are produced and subsequently discarded. An extraction protocol to obtain essential oils, dihydro-5,6-dehydrokawain (DDK) and enriched antioxidant phenolic extracts from fresh leaves or rhizomes of alpinia and its waste was developed.
