Volatile constituents of essential oils isolated from the inflorescence and leaf of anisomeles indica [L.] O. Ktze.

The composition of the inflorescence and leaf essential oil of Anisomeles indica [L] O. Ktze. from Bangladesh was examined by GC-MS. Seventy-six components were identified in Inflorescence oil and 52 components were identified in leaf oil, accounting for 98.6% and 98.96% of the total yields, respectively. The main component in inflorescence oil was citronellyl propionate [16.12%]; citronellyl epoxide [13.71%]; [+] agathadiop [9.59%] and pinol D [7.58%]. On the other hand, leaf oil contained caryophyllene [62.52%], cadina, 1, 4-diene [5.50%] and triethanol amine [5.14%]. The composition of both oils varied qualitatively and quantitatively

Essential oil analysis of callstemon lanceolatus DC. leaves from Bangladesh

Two samples of the essential oil obtained by hydrodistillation from leaves of Callistemon lanceolatus DC was analyzed by GC-MS. The oil yield was 0.70%. Fifty compounds were identified in the leaf oil. 1,8-cineole [51.22%], [E]-ocimene [22.89%], terpinyl acetate [7.46%] and beta-pinene [2.09%] were the major components representing 97.5% of the oil. The compositions of both oil samples varied qualitatively and quantitatively

Investigation on three types of aloe species from Bangladesh
