The plumule of Nelumbo nucif era Gaertn. ,
( PNN) has a good function in elimina ting the her-
ar t-fi re, low ering the high blood pressure and toni-
fying the heart which are rela ted wi th the alkaloid
consti tuents in PNN
[1, 2 ]
. Great much investiga tion
has been put on the alkaloid consti tuents, but li t tle
has been repor ted about the vola ti le oil f rom PNN
so far. Now the analytic resul ts by means of GC-
M S a re repo rted in the followings.
The 95% EtO H ex tract o f PNN was pa rti-
tioned wi th chloro fo rm, the oil pa rt in chlo ro fo rm
w as esterified w ith 0. 4 mol /L sodium hydroxyl
methano l solution just befo re the GC-M S analysis,
the analysis w as performed on HP6890 / HP5973
GC-M S ( HP. USA. ) a t room tempera ture.
GC condition: HP-5 5% Prenyl M ennyl Silox-
ane 30 m× 0. 25 mm, 0. 25μm qua rtz capi llary col-
umn; prog rammed temperature: 60℃ ( 3 min) →
10℃ /min→ 280℃ ( 10 min) ; inlet tempera ture:
280℃ ; ca rrier gas: Helium ( 99. 999% ) w ith the
f lux o f 1. 0 mL /min; sample size: 1μL; the split
ra tio is 40∶ 1.
Results: The assuring consti tuents in PNN
a re listed in Table 1, among which several v ery im-
portant natural products show a high quanti ty. Vi-
tamin E is w ell know n a kind o f antiox idants; si to s-

the squalene plays an important role in cancer pre-
vention and it can also ameliorate the blood ci rcula-
tion, and some fat ty acid are consti tuents o f cell
membrane. Considering all the valuable con-
sti tuents, PNN is sure to play more important ro le
fo r people s health in the near future.
