4.7. Activity against C. albicans
Compounds 1, 2, 3 and 4 were tested for antifungal
activity according to a modified NCCLS micro dilution
assay procedure. All tests were carried out using sterile
96-well plates and Saburaud dextrose broth-SDB
(Sigma). The log phase inoculum was obtained by incu-

bating C. albicans (ATCC 10231) for 48 h at 30 C on
Saburaud dextrose agar plates. The compounds were
dissolved in either H2O or MeOH–H2O combination.
Solutions of each test compound were further diluted
with SDB yielding their final concentration. Each sapo-
nin was evaluated in triplicate in a dose–response format
where the final concentrations were 1, 25, 50, 100 and 500
mg/ml and where the final fungal concentration was 2 ꢁ
103 cfu. To each well containing double the final sapo-
nin dilution, an equal volume of the inoculum suspen-
sion containing double the final fungal concentration
was added. The minimum inhibitory concentration
(MIC), the lowest concentration of the test compound
resulting in the complete inhibition of growth, was
determined visually. Amphotericin B (Sigma) at 1 mg/ml
final concentration was used as a positive control.

0.01, 0.005 and 0.001 mg/ml) in PBS at 37 C for 30
min. This mixture was centrifuged (2500 g, 30 min) and
the hemoglobin content in the supernatant was mea-
sured at 490 nm using a multiwell spectrophotometer
(Virion autoReader A) by transferring 200 ml to 96-well
microtiter plates. Parallel measurements of saponin dilu-
tions without erythrocytes, erythrocytes without saponin
dilutions and buffer without both erythrocytes and
saponin dilutions were made. The results were then
compared to a positive control sample containing ery-
throcytes in distilled water. The 50% hemolysing con-
centrations (HC50) of each saponin were then inferred
from the hemoglobin absorbance vs saponin concentra-
tion curve.
