Essential Oil Analysis of Illicium anistum L. Extracts

Abstract

Fresh japanese anise (Illicium anisatum L.) tree leaves were collected and ground after drying. The essential oils of the leaves were analyzed by gas chromatography-mass spectrometry (GC-MS) using headspace (HS) and solid phase-microextra (SPME) methods.Volatile components of the leaves were identified 21 and 65 components in HS and SPME, respectively. The main components of the essential oils obtained by HS method were eucalyptol (36.7%), (+)-sabinene (15.61%), δ -3-carene (6.87%), α -pinene (6.07%), γ -terpinen (5.72%), α -limonene (5.26%), β -myrcene (4.13%), α -terpinene (4.04%) and β -pinene (3.73%). The other components were less than 3.5%. SPME method also showed that eucalyptol (17.88%) was main. The other were 5-allyl-1-methoxy-2 (13.29%), caryophyllene (6.09%), (+)-sabinene (5.60%), α -ocimene (4.89%) and β -myrcene (3.73%), and the rest were less amounts than 3.5%. This work indicated that many more volatile components were isolated, comparing to the previous literature data and that SPME method was much more effective than HS method in the analysis of the volatile components.

Chemical composition, seasonal variation and antiaging activities of essential oil from Callistemon subulatus leaves growing in Egypt

“…The C. subulatus leaf oil of winter showed an inhibition to elastase activity with IC 50 value of 1.05 ± 0.05 µg/mL, compared to the standard N-methoxysuccinyl-Ala-Ala-Pro-Val-chloromethyl ketone (IC 50 = 0.55 ± 0.03 µg/mL). The essential oil of Illicium anisatum containing eucalyptol as a major component (36.7%) was able to inhibit elastase (IC 50 = 1.79 mg/mL) 35 . Eucalyptol was one of the most abundant terpenes (11.82%) in Mentha viridis essential oil that showed elastase inhibition by IC 50 = 114.24 ± 1.22 µg/mL 36 .…”

Antibacterial Activity of Defensive Secretions from the Lace Bug Stephanitis svensoni (Drake) (Hemiptera: Tingidae)

“…When hexane extracts of the leaves from the host plant, I. anisatum, were analyzed by GC-MS, no compounds identical to those of the nymph extracts were detected, except for hydrocarbons. Furthermore, no previous papers on the components of I. anisatum leaves have described compounds detected in nymph extracts [25][26][27][28]. Thus, compounds 1-10 were suggested to be exocrine secretions from nymphs.…”

Crataegus pinnatifida Bunge root extract induces apoptosis of murine lung carcinoma cells in vitro

“…Other parts of the C. pinnatifida plant also have therapeutic potential. For example, the leaves, wood, bark, and fruit have all been shown to have an antioxidant activity [24][25][26]. The leaves of C. pinnatifida have anti-allergic effect [23], and the wood and bark have anti-inflammatory effects [25].…”

“…For example, the leaves, wood, bark, and fruit have all been shown to have an antioxidant activity [24][25][26]. The leaves of C. pinnatifida have anti-allergic effect [23], and the wood and bark have anti-inflammatory effects [25]. Furthermore, it has been reported that C. pinnatifida fruit has antitumor effects in gastrointestinal cancer [27].…”
