| description | The study was aimed to investigate the chemical components of stem and fruit volatile oils of Piper. maingayi Hk. with their antioxidant and antityrosinase activities. GC and GC-MS analysis of the essential oils obtained from the fresh stem and fruit of P. maingayi Hk. resulted in the identification of 34 and 18 components accounting for 83.6% and 78.7% of the total amount, respectively. Sesquiterpene hydrocarbons and oxygenated sesquiterpenes were the most highly represented classes as the former ranging from 64.7% to 70.7%, and the latter varying from 7.4% to 8.6%. The main constituents of the stem oil were: β-caryophyllene (26.2%), -cedrene (8.4%), caryophyllene oxide (6.7%) and cis-calamenene (6.2%), while the fruit oil was dominated by δ-cadinene (22.6%), β-caryophyllene (18.8%), -copaene (11.2%) and -cadinol (7.1%). The stem and fruit of P. maingayi oils showed significant value for antioxidant and antityrosinase activities.
Kajian ini bertujuan untuk mengkaji komponen kimia daripada minyak pati batang dan
buah Piper. maingayi Hk. serta aktiviti antioksidan dan antitirosinase. Analisis GC dan GCMS
minyak pati yang diperoleh daripada batang dan buah segar P. maingayi Hk.
menghasilkan pengecaman 34 dan 18 komponen menyumbang kepada masing-masing
83.6% dan 78.7% daripada jumlah keseluruhan. Hidrokarbon seskuiterpena dan
seskuiterpena teroksigen mewakili kelas tertinggi dengan yang pertama menyumbang
diantara 64.7% hingga 70.7%, dan keduanya daripada 7.4% hingga 8.6%. Kandungan
utama minyak pati dahan ialah: β-kariofilena (26.2%), -sedrena (8.4%), kariofilena oksida
(6.7%) dan cis-kalamenena (6.2%), manakala minyak buah didominasi oleh δ-kadinena
(22.6%), β- kariofilena (18.8%), -kopaena (11.2%) dan -kadinol (7.1%). Minyak pati batang
dan buah P. maingayi menunjukkan nilai yang signifikan untuk aktiviti antioksidan dan
antitirosinase. |
